Instance Methods

tasks()

Returns the tasks Resource.

close()

Close httplib2 connections.

create(parent, body=None, x__xgafv=None)

Creates a queue. Queues created with this method allow tasks to live for a maximum of 31 days. After a task is 31 days old, the task will be deleted regardless of whether it was dispatched or not. WARNING: Using this method may have unintended side effects if you are using an App Engine `queue.yaml` or `queue.xml` file to manage your queues. Read [Overview of Queue Management and queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using this method.

delete(name, x__xgafv=None)

Deletes a queue. This command will delete the queue even if it has tasks in it. Note: If you delete a queue, you may be prevented from creating a new queue with the same name as the deleted queue for a tombstone window of up to 3 days. During this window, the CreateQueue operation may appear to recreate the queue, but this can be misleading. If you attempt to create a queue with the same name as one that is in the tombstone window, run GetQueue to confirm that the queue creation was successful. If GetQueue returns 200 response code, your queue was successfully created with the name of the previously deleted queue. Otherwise, your queue did not successfully recreate. WARNING: Using this method may have unintended side effects if you are using an App Engine `queue.yaml` or `queue.xml` file to manage your queues. Read [Overview of Queue Management and queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using this method.

get(name, readMask=None, x__xgafv=None)

Gets a queue.

getIamPolicy(resource, body=None, x__xgafv=None)

Gets the access control policy for a Queue. Returns an empty policy if the resource exists and does not have a policy set. Authorization requires the following [Google IAM](https://cloud.google.com/iam) permission on the specified resource parent: * `cloudtasks.queues.getIamPolicy`

list(parent, filter=None, pageSize=None, pageToken=None, readMask=None, x__xgafv=None)

Lists queues. Queues are returned in lexicographical order.

list_next()

Retrieves the next page of results.

patch(name, body=None, updateMask=None, x__xgafv=None)

Updates a queue. This method creates the queue if it does not exist and updates the queue if it does exist. Queues created with this method allow tasks to live for a maximum of 31 days. After a task is 31 days old, the task will be deleted regardless of whether it was dispatched or not. WARNING: Using this method may have unintended side effects if you are using an App Engine `queue.yaml` or `queue.xml` file to manage your queues. Read [Overview of Queue Management and queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using this method.

pause(name, body=None, x__xgafv=None)

Pauses the queue. If a queue is paused then the system will stop dispatching tasks until the queue is resumed via ResumeQueue. Tasks can still be added when the queue is paused. A queue is paused if its state is PAUSED.

purge(name, body=None, x__xgafv=None)

Purges a queue by deleting all of its tasks. All tasks created before this method is called are permanently deleted. Purge operations can take up to one minute to take effect. Tasks might be dispatched before the purge takes effect. A purge is irreversible.

resume(name, body=None, x__xgafv=None)

Resume a queue. This method resumes a queue after it has been PAUSED or DISABLED. The state of a queue is stored in the queue's state; after calling this method it will be set to RUNNING. WARNING: Resuming many high-QPS queues at the same time can lead to target overloading. If you are resuming high-QPS queues, follow the 500/50/5 pattern described in [Managing Cloud Tasks Scaling Risks](https://cloud.google.com/tasks/docs/manage-cloud-task-scaling).

setIamPolicy(resource, body=None, x__xgafv=None)

Sets the access control policy for a Queue. Replaces any existing policy. Note: The Cloud Console does not check queue-level IAM permissions yet. Project-level permissions are required to use the Cloud Console. Authorization requires the following [Google IAM](https://cloud.google.com/iam) permission on the specified resource parent: * `cloudtasks.queues.setIamPolicy`

testIamPermissions(resource, body=None, x__xgafv=None)

Returns permissions that a caller has on a Queue. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error. Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Note: The debugging command, RunTask, will run a task even if the queue has reached its RateLimits. # Rate limits for task dispatches. rate_limits and retry_config are related because they both control task attempts however they control how tasks are attempted in different ways: * rate_limits controls the total rate of dispatches from a queue (i.e. all traffic dispatched from the queue, regardless of whether the dispatch is from a first attempt or a retry). * retry_config controls what happens to particular a task after its first attempt fails. That is, retry_config controls task retries (the second attempt, third attempt, etc).
    "maxBurstSize": 42, # The max burst size. Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The [token bucket](https://wikipedia.org/wiki/Token_Bucket) algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by `max_burst_size`. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. The default value of `max_burst_size` is picked by Cloud Tasks based on the value of max_dispatches_per_second. The maximum value of `max_burst_size` is 500. For App Engine queues that were created or updated using `queue.yaml/xml`, `max_burst_size` is equal to [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size). If UpdateQueue is called on a queue without explicitly setting a value for `max_burst_size`, `max_burst_size` value will get updated if UpdateQueue is updating max_dispatches_per_second.

After this threshold has been reached, Cloud Tasks stops dispatching tasks until the number of concurrent requests decreases. If unspecified when the queue is created, Cloud Tasks will pick the default. The maximum allowed value is 5,000. This field is output only for pull queues and always -1, which indicates no limit. No other queue types can have `max_concurrent_tasks` set to -1. This field has the same meaning as [max_concurrent_requests in queue.yaml/xml](https://cloud.google.com/appengine/docs/standard/python/config/queueref#max_concurrent_requests).
    "maxTasksDispatchedPerSecond": 3.14, # The maximum rate at which tasks are dispatched from this queue. If unspecified when the queue is created, Cloud Tasks will pick the default. * For App Engine queues, the maximum allowed value is 500. * This field is output only for pull queues. In addition to the `max_tasks_dispatched_per_second` limit, a maximum of 10 QPS of LeaseTasks requests are allowed per pull queue. This field has the same meaning as [rate in queue.yaml/xml](https://cloud.google.com/appengine/docs/standard/python/config/queueref#rate).
  },
  "retryConfig": { # Retry config. These settings determine how a failed task attempt is retried. # Settings that determine the retry behavior. * For tasks created using Cloud Tasks: the queue-level retry settings apply to all tasks in the queue that were created using Cloud Tasks. Retry settings cannot be set on individual tasks. * For tasks created using the App Engine SDK: the queue-level retry settings apply to all tasks in the queue which do not have retry settings explicitly set on the task and were created by the App Engine SDK.

If unspecified when the queue is created, Cloud Tasks will pick the default. This field is output only for pull queues. `max_backoff` will be truncated to the nearest second. This field has the same meaning as [max_backoff_seconds in queue.yaml/xml](https://cloud.google.com/appengine/docs/standard/python/config/queueref#retry_parameters).
    "maxDoublings": 42, # The time between retries will double `max_doublings` times. A task's retry interval starts at min_backoff, then doubles `max_doublings` times, then increases linearly, and finally retries at intervals of max_backoff up to max_attempts times. For example, if min_backoff is 10s, max_backoff is 300s, and `max_doublings` is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of max_backoff until the task has been attempted max_attempts times. Thus, the requests will retry at 10s, 20s, 40s, 80s, 160s, 240s, 300s, 300s, .... If unspecified when the queue is created, Cloud Tasks will pick the default.

    "maxRetryDuration": "A String", # If positive, `max_retry_duration` specifies the time limit for retrying a failed task, measured from when the task was first attempted. Once `max_retry_duration` time has passed *and* the task has been attempted max_attempts times, no further attempts will be made and the task will be deleted. If zero, then the task age is unlimited. If unspecified when the queue is created, Cloud Tasks will pick the default. This field is output only for pull queues. `max_retry_duration` will be truncated to the nearest second. This field has the same meaning as [task_age_limit in queue.yaml/xml](https://cloud.google.com/appengine/docs/standard/python/config/queueref#retry_parameters).
    "minBackoff": "A String", # A task will be scheduled for retry between min_backoff and max_backoff duration after it fails, if the queue's RetryConfig specifies that the task should be retried.

    "tasksCount": "A String", # Output only. An estimation of the number of tasks in the queue, that is, the tasks in the queue that haven't been executed, the tasks in the queue which the queue has dispatched but has not yet received a reply for, and the failed tasks that the queue is retrying.
  },
  "taskTtl": "A String", # The maximum amount of time that a task will be retained in this queue. Queues created by Cloud Tasks have a default `task_ttl` of 31 days. After a task has lived for `task_ttl`, the task will be deleted regardless of whether it was dispatched or not. The `task_ttl` for queues created via queue.yaml/xml is equal to the maximum duration because there is a [storage quota](https://cloud.google.com/appengine/quotas#Task_Queue) for these queues. To view the maximum valid duration, see the documentation for Duration.
  "tombstoneTtl": "A String", # The task tombstone time to live (TTL). After a task is deleted or completed, the task's tombstone is retained for the length of time specified by `tombstone_ttl`. The tombstone is used by task de-duplication; another task with the same name can't be created until the tombstone has expired. For more information about task de-duplication, see the documentation for CreateTaskRequest. Queues created by Cloud Tasks have a default `tombstone_ttl` of 1 hour.

That is, retry_config controls task retries (the second attempt, third attempt, etc).
    "maxBurstSize": 42, # The max burst size. Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The [token bucket](https://wikipedia.org/wiki/Token_Bucket) algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by `max_burst_size`. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. The default value of `max_burst_size` is picked by Cloud Tasks based on the value of max_dispatches_per_second. The maximum value of `max_burst_size` is 500. For App Engine queues that were created or updated using `queue.yaml/xml`, `max_burst_size` is equal to [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size).

    "maxDoublings": 42, # The time between retries will double `max_doublings` times. A task's retry interval starts at min_backoff, then doubles `max_doublings` times, then increases linearly, and finally retries at intervals of max_backoff up to max_attempts times. For example, if min_backoff is 10s, max_backoff is 300s, and `max_doublings` is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of max_backoff until the task has been attempted max_attempts times.

delete(name, x__xgafv=None)
Deletes a queue. This command will delete the queue even if it has tasks in it. Note: If you delete a queue, you may be prevented from creating a new queue with the same name as the deleted queue for a tombstone window of up to 3 days. During this window, the CreateQueue operation may appear to recreate the queue, but this can be misleading. If you attempt to create a queue with the same name as one that is in the tombstone window, run GetQueue to confirm that the queue creation was successful. If GetQueue returns 200 response code, your queue was successfully created with the name of the previously deleted queue. Otherwise, your queue did not successfully recreate. WARNING: Using this method may have unintended side effects if you are using an App Engine `queue.yaml` or `queue.xml` file to manage your queues. Read [Overview of Queue Management and queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using this method.

Note: The debugging command, RunTask, will run a task even if the queue has reached its RateLimits. # Rate limits for task dispatches. rate_limits and retry_config are related because they both control task attempts however they control how tasks are attempted in different ways: * rate_limits controls the total rate of dispatches from a queue (i.e. all traffic dispatched from the queue, regardless of whether the dispatch is from a first attempt or a retry). * retry_config controls what happens to particular a task after its first attempt fails. That is, retry_config controls task retries (the second attempt, third attempt, etc).
    "maxBurstSize": 42, # The max burst size. Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The [token bucket](https://wikipedia.org/wiki/Token_Bucket) algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by `max_burst_size`. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. The default value of `max_burst_size` is picked by Cloud Tasks based on the value of max_dispatches_per_second. The maximum value of `max_burst_size` is 500. For App Engine queues that were created or updated using `queue.yaml/xml`, `max_burst_size` is equal to [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size). If UpdateQueue is called on a queue without explicitly setting a value for `max_burst_size`, `max_burst_size` value will get updated if UpdateQueue is updating max_dispatches_per_second.

This field has the same meaning as [max_backoff_seconds in queue.yaml/xml](https://cloud.google.com/appengine/docs/standard/python/config/queueref#retry_parameters).
    "maxDoublings": 42, # The time between retries will double `max_doublings` times. A task's retry interval starts at min_backoff, then doubles `max_doublings` times, then increases linearly, and finally retries at intervals of max_backoff up to max_attempts times. For example, if min_backoff is 10s, max_backoff is 300s, and `max_doublings` is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of max_backoff until the task has been attempted max_attempts times. Thus, the requests will retry at 10s, 20s, 40s, 80s, 160s, 240s, 300s, 300s, .... If unspecified when the queue is created, Cloud Tasks will pick the default.

    { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).

Each occurrence of a principal counts towards these limits. For example, if the `bindings` grant 50 different roles to `user:alice@example.com`, and not to any other principal, then you can add another 1,450 principals to the `bindings` in the `Policy`.

Note: The debugging command, RunTask, will run a task even if the queue has reached its RateLimits. # Rate limits for task dispatches. rate_limits and retry_config are related because they both control task attempts however they control how tasks are attempted in different ways: * rate_limits controls the total rate of dispatches from a queue (i.e. all traffic dispatched from the queue, regardless of whether the dispatch is from a first attempt or a retry). * retry_config controls what happens to particular a task after its first attempt fails. That is, retry_config controls task retries (the second attempt, third attempt, etc).
        "maxBurstSize": 42, # The max burst size. Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The [token bucket](https://wikipedia.org/wiki/Token_Bucket) algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by `max_burst_size`. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. The default value of `max_burst_size` is picked by Cloud Tasks based on the value of max_dispatches_per_second. The maximum value of `max_burst_size` is 500. For App Engine queues that were created or updated using `queue.yaml/xml`, `max_burst_size` is equal to [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size). If UpdateQueue is called on a queue without explicitly setting a value for `max_burst_size`, `max_burst_size` value will get updated if UpdateQueue is updating max_dispatches_per_second.

No other queue types can have `max_concurrent_tasks` set to -1.

If unspecified when the queue is created, Cloud Tasks will pick the default. This field is output only for pull queues. `max_backoff` will be truncated to the nearest second. This field has the same meaning as [max_backoff_seconds in queue.yaml/xml](https://cloud.google.com/appengine/docs/standard/python/config/queueref#retry_parameters).
        "maxDoublings": 42, # The time between retries will double `max_doublings` times. A task's retry interval starts at min_backoff, then doubles `max_doublings` times, then increases linearly, and finally retries at intervals of max_backoff up to max_attempts times. For example, if min_backoff is 10s, max_backoff is 300s, and `max_doublings` is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of max_backoff until the task has been attempted max_attempts times. Thus, the requests will retry at 10s, 20s, 40s, 80s, 160s, 240s, 300s, 300s, .... If unspecified when the queue is created, Cloud Tasks will pick the default.

If unspecified when the queue is created, Cloud Tasks will pick the default. This field is output only for pull queues. `max_retry_duration` will be truncated to the nearest second.

    "maxBurstSize": 42, # The max burst size. Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The [token bucket](https://wikipedia.org/wiki/Token_Bucket) algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by `max_burst_size`. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. The default value of `max_burst_size` is picked by Cloud Tasks based on the value of max_dispatches_per_second. The maximum value of `max_burst_size` is 500. For App Engine queues that were created or updated using `queue.yaml/xml`, `max_burst_size` is equal to [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size).

A task's retry interval starts at min_backoff, then doubles `max_doublings` times, then increases linearly, and finally retries at intervals of max_backoff up to max_attempts times. For example, if min_backoff is 10s, max_backoff is 300s, and `max_doublings` is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of max_backoff until the task has been attempted max_attempts times.

    "maxBurstSize": 42, # The max burst size. Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The [token bucket](https://wikipedia.org/wiki/Token_Bucket) algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by `max_burst_size`. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. The default value of `max_burst_size` is picked by Cloud Tasks based on the value of max_dispatches_per_second. The maximum value of `max_burst_size` is 500. For App Engine queues that were created or updated using `queue.yaml/xml`, `max_burst_size` is equal to [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size). If UpdateQueue is called on a queue without explicitly setting a value for `max_burst_size`, `max_burst_size` value will get updated if UpdateQueue is updating max_dispatches_per_second.

This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The [token bucket](https://wikipedia.org/wiki/Token_Bucket) algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by `max_burst_size`. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. The default value of `max_burst_size` is picked by Cloud Tasks based on the value of max_dispatches_per_second. The maximum value of `max_burst_size` is 500. For App Engine queues that were created or updated using `queue.yaml/xml`, `max_burst_size` is equal to [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size).

That is, retry_config controls task retries (the second attempt, third attempt, etc).
    "maxBurstSize": 42, # The max burst size. Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time. The [token bucket](https://wikipedia.org/wiki/Token_Bucket) algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by `max_burst_size`. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue's bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on max_dispatches_per_second. The default value of `max_burst_size` is picked by Cloud Tasks based on the value of max_dispatches_per_second. The maximum value of `max_burst_size` is 500. For App Engine queues that were created or updated using `queue.yaml/xml`, `max_burst_size` is equal to [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size).

A task's retry interval starts at min_backoff, then doubles `max_doublings` times, then increases linearly, and finally retries at intervals of max_backoff up to max_attempts times. For example, if min_backoff is 10s, max_backoff is 300s, and `max_doublings` is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of max_backoff until the task has been attempted max_attempts times.

  "policy": { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/). # REQUIRED: The complete policy to be applied to the `resource`.

Each of the `bindings` must contain at least one principal. The `bindings` in a `Policy` can refer to up to 1,500 principals; up to 250 of these principals can be Google groups. Each occurrence of a principal counts towards these limits. For example, if the `bindings` grant 50 different roles to `user:alice@example.com`, and not to any other principal, then you can add another 1,450 principals to the `bindings` in the `Policy`.

For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).
  "bindings": [ # Associates a list of `members`, or principals, with a `role`. Optionally, may specify a `condition` that determines how and when the `bindings` are applied. Each of the `bindings` must contain at least one principal. The `bindings` in a `Policy` can refer to up to 1,500 principals; up to 250 of these principals can be Google groups. Each occurrence of a principal counts towards these limits. For example, if the `bindings` grant 50 different roles to `user:alice@example.com`, and not to any other principal, then you can add another 1,450 principals to the `bindings` in the `Policy`.
    { # Associates `members`, or principals, with a `role`.
      "condition": { # Represents a textual expression in the Common Expression Language (CEL) syntax. CEL is a C-like expression language.

  "etag": "A String", # `etag` is used for optimistic concurrency control as a way to help prevent simultaneous updates of a policy from overwriting each other. It is strongly suggested that systems make use of the `etag` in the read-modify-write cycle to perform policy updates in order to avoid race conditions: An `etag` is returned in the response to `getIamPolicy`, and systems are expected to put that etag in the request to `setIamPolicy` to ensure that their change will be applied to the same version of the policy. **Important:** If you use IAM Conditions, you must include the `etag` field whenever you call `setIamPolicy`. If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost.
  "version": 42, # Specifies the format of the policy. Valid values are `0`, `1`, and `3`. Requests that specify an invalid value are rejected. Any operation that affects conditional role bindings must specify version `3`.

If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset.

testIamPermissions(resource, body=None, x__xgafv=None)
Returns permissions that a caller has on a Queue. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error. Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Args:
  resource: string, REQUIRED: The resource for which the policy detail is being requested. See [Resource names](https://cloud.google.com/apis/design/resource_names) for the appropriate value for this field. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for `TestIamPermissions` method.
  "permissions": [ # The set of permissions to check for the `resource`. Permissions with wildcards (such as `*` or `storage.*`) are not allowed. For more information see [IAM Overview](https://cloud.google.com/iam/docs/overview#permissions).

  ],
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Response message for `TestIamPermissions` method.
  "permissions": [ # A subset of `TestPermissionsRequest.permissions` that the caller is allowed.
    "A String",
  ],
