One of the responsibilities of backend web API developers is to provide proper documentation for frontend application developers so that they can consume APIs without any problems. In order to consume any API, the following are the two minimum topics that one needs to understand:
- The input parameters and their data types
- The output parameters and their data types
So, it's the responsibility of the backend developers to provide proper documentation for APIs; as it's not easy to provide proper documentation, there are many tools and standards/specifications that are available for providing proper documentation for REST APIs. One such standard is known as the open API specification (it's popularly known as Swagger).
