Generated API Clients (GAPICs) are produced from declarative descriptions of APIs. These API descriptions are written in the Protocol Buffer language and build on nearly 20 years of experience describing APIs within Google.
Our GAPIC generators are open source and are published in github.com/googleapis. The original gapic-generator produced API clients in seven languages and continues to be the preferred generator for Java and PHP.
In 2018, we began developing a new set of generators, each written in the language that it generates. Some of our language-specific GAPIC generators are listed below:
To verify GAPIC generator implementations, we test them with a common gapic-showcase API that “showcases” important GAPIC features.
For questions on a specific GAPIC generator, please file an issue on the corresponding repository.
