Gateway endpoint is the URL that is used to access an API through API Gateway. By default, API Gateway provides a default gateway endpoint for all active APIs. The default gateway endpoint is in the protocol://host:port/{defaultPrefix}/{apiName}/{apiVersion}/{resourcePath} format.

When there is a need to access the API using a different endpoint, you can define a custom gateway endpoint. In custom gateway endpoints, you can customize the portion of the URL between port and resourcePath.

Custom gateway endpoints can be specific to an API or a global template can be defined through global gateway endpoint.
