API keys are associated with the Google Cloud project in which they have been created. If your API requires an API key, you either have to give your API users a key from the project that you created the Cloud Endpoints service in, or you can let users enable your API in their own Google Cloud project and create an API key. This page shows you how to grant the permission that users need to enable your API.
Endpoints uses the Identity and Access Management (IAM) Service Consumer role to allow someone who isn't a member of your Google Cloud project to enable your API in their own Google Cloud project. This section shows you how to grant access using the Google Cloud console or the Google Cloud CLI.
You revoke access to your API by removing the Service Consumer role from a user or group that previously had the role. After you revoke someone's access, they won't be able to enable your API.
