Endpoint URL and Invoke URL

Each API of Amazon API Gateway has

• a default endpoint (aka hostname of the API) in the format of
  • {api-id}.execute-api.{region}.amazonaws.com, or
  • {hostname}

Each stage is available for client applications to call via

• a base URL in the format of
  • {protocol}://{hostname}/{stage}, or
  • https://{api-id}.execute-api.{region}.amazonaws.com/{stage} (for REST API Gateway in our case).

To call a deployed API, the client submits a request against

• an Invoke URL in the format of
  • {protocol}://{hostname}/{stage}{resourcePath}, or
  • https://{api-id}.execute-api.{region}.amazonaws.com/{stage}{resourcePath} (for REST API Gateway in our case).

For example:

• The stage dev of a REST API is available at the Invoke URL: https://{api-id}.execute-api.{region}.amazonaws.com/dev

• The root resource / of stage dev of the same REST API is available at the Invoke URL: https://{api-id}.execute-api.{region}.amazonaws.com/dev/

• The resource users of stage dev of the same REST API is available at the Invoke URL: https://{api-id}.execute-api.{region}.amazonaws.com/dev/users
