Where in AWS API Gateway Console is the option to Set up asynchronous invocation of the backend Lambda function

Question

Older posts with similar title do not answer the question based on the current (March 2021) AWS API Gateway console.

The AWS docs say "In Integration Request, add an X-Amz-Invocation-Type header with a static value of 'Event'."

But on the API Gateway console after a full hour of looking under rocks I do not see "Integration Request" anywhere?

Answer 1

You can't find "Integration Request", because this is property of only REST API, not HTTP API.

Specifically, if you want to manage headers for lambda invocations, you have to use Lambda custom integration, not the more commonly used proxy integration.
