How to attach or update an API gateway resource policy using boto3

Question

Is there any method in boto3 which will attach or update the resource policy in api -gateway?

I searched in the boto3 documentation, but didn't find any method.

Answer 1

You want to use the create_rest_api method for attaching, and the update_rest_api method for updating. The Create and Attach an API Gateway Resource Policy to an API documentation for the CLI/API should be of help in describing the patchOperations values you should use to update an existing policy.

Be sure to redeploy as the documentation states:

Important

If you attach a resource policy to a deployed API, or if you update an existing resource policy, you'll need to redeploy the API for the changes to take effect.
