create(userId, body=None, media_body=None, media_mime_type=None, x__xgafv=None)
Creates a new draft with the `DRAFT` label.

Replaces a draft's content.

Args:
  userId: string, The user's email address. The special value `me` can be used to indicate the authenticated user. (required)
  id: string, The ID of the draft to update. (required)
  body: object, The request body.
    The object takes the form of:

{ # A draft email in the user's mailbox.
  "id": "A String", # The immutable ID of the draft.
  "message": { # An email message. # The message content of the draft.
    "historyId": "A String", # The ID of the last history record that modified this message.
    "id": "A String", # The immutable ID of the message.
    "internalDate": "A String", # The internal message creation timestamp (epoch ms), which determines ordering in the inbox. For normal SMTP-received email, this represents the time the message was originally accepted by Google, which is more reliable than the `Date` header. However, for API-migrated mail, it can be configured by client to be based on the `Date` header.
    "labelIds": [ # List of IDs of labels applied to this message.
      "A String",
    ],
    "payload": { # A single MIME message part. # The parsed email structure in the message parts.
      "body": { # The body of a single MIME message part. # The message part body for this part, which may be empty for container MIME message parts.
        "attachmentId": "A String", # When present, contains the ID of an external attachment that can be retrieved in a separate `messages.attachments.get` request. When not present, the entire content of the message part body is contained in the data field.
        "data": "A String", # The body data of a MIME message part as a base64url encoded string. May be empty for MIME container types that have no message body or when the body data is sent as a separate attachment. An attachment ID is present if the body data is contained in a separate attachment.
        "size": 42, # Number of bytes for the message part data (encoding notwithstanding).
      },
      "filename": "A String", # The filename of the attachment. Only present if this message part represents an attachment.
      "headers": [ # List of headers on this message part. For the top-level message part, representing the entire message payload, it will contain the standard RFC 2822 email headers such as `To`, `From`, and `Subject`.
        {
          "name": "A String", # The name of the header before the `:` separator. For example, `To`.
          "value": "A String", # The value of the header after the `:` separator. For example, `someuser@example.com`.
        },
      ],
      "mimeType": "A String", # The MIME type of the message part.
      "partId": "A String", # The immutable ID of the message part.
      "parts": [ # The child MIME message parts of this part. This only applies to container MIME message parts, for example `multipart/*`. For non- container MIME message part types, such as `text/plain`, this field is empty. For more information, see RFC 1521.
        # Object with schema name: MessagePart
      ],
    },
    "raw": "A String", # The entire email message in an RFC 2822 formatted and base64url encoded string. Returned in `messages.get` and `drafts.get` responses when the `format=RAW` parameter is supplied.
    "sizeEstimate": 42, # Estimated size in bytes of the message.
    "snippet": "A String", # A short part of the message text.
    "threadId": "A String", # The ID of the thread the message belongs to. To add a message or draft to a thread, the following criteria must be met: 1. The requested `threadId` must be specified on the `Message` or `Draft.Message` you supply with your request. 2. The `References` and `In-Reply-To` headers must be set in compliance with the [RFC 2822](https://tools.ietf.org/html/rfc2822) standard. 3. The `Subject` headers must match.
  },
}

  media_body: string, The filename of the media request body, or an instance of a MediaUpload object.
  media_mime_type: string, The MIME type of the media request body, or an instance of a MediaUpload object.
