How can I ref API gateway endpoint in serverless?

Question

I am using serverless.yml as the infra. framework. I create a lambda with a API gateway like below code:

functions:
  create:
    handler: posts.create
    events:
      - http:
          path: posts/create
          method: post
          authorizer: xxx:xxx:Lambda-Name

it will generate a endpoint for the API gateway. But how can I reference this endpoint in other place in the yml file?

Ref: ApiGatewayRestApi - ApiGatewayRestApi is a default Rest API logical ID.

How do I get/reference API gateway restAPI id in serverless.yml?

          - - 'https://'
            - Ref: ApiGatewayRestApi
            - '.execute-api.'
            - Ref: AWS::Region
            - '.amazonaws.com/'
