Creating an API server

You must define an API server that uses the API or APIs you have created. To define an API server:

  1. Create a Python module, for example, and create an endpoints.api_server object at the top-level:

    Note that you provide a list of remote.Service objects to the API server. If you have an API that is is implemented in several classes, then your Service object is a collection of classes as described in Creating an API Implemented with Multiple Classes.

    Notice that we describe using a separate module for the API server: this is not a requirement! If you are defining multiple APIs (remote.Service subclasses) that are defined in multiple files, it might be preferable to have a separate module for your API Server in order to import all these class files. However, alternatively, you could just add the required endpoints.api_server code shown above to the module where you define your API. If you are defining only a single API, it may be preferable to define the API server in the same file where you define your API because it doesn't need to import any other classes.

  2. In your app.yaml file, map the API server you just created to the endpoints location as follows:

    where main is the Python module you used for your API server module. Notice that the endpoints path must be /_ah/spi relative to the application. Although applications send their requests to /_ah/api, the Endpoints backend actually handles these requests at the path /_ah/spi.

  3. Add Endpoints to the Libraries section of app.yaml, since the Endpoints library is not included by default:

    Note that you should specify the desired Endpoints library version. Currently, the only version available is the GA version, 1.0.
