Binding a Signature Key

Function

A signature key takes effect only after being bound to an API. When requesting the backend service, APIG uses the signature key to cryptographically sign requests. The backend service verifies the signature to identify request sources.

This API is used to bind a signature key to one or more published APIs.

Different signature keys can be bound to an API in different environments, but only one signature key can be bound to the API in the same environment.
