How can I restrict specific parameters in payload from API Gateway to AWS Lambda?

I have to send a request body (payload) from API Gateway to AWS Lambda. In that payload, I only need to send:

{
    "path":"aaa"
    "action":"xyz"
}

If someone passes any other parameter in the payload, it should not accept the payload and show an error message. Could somebody please help me with the logic?

For AWS API Gateway you can implement request validation using an OpenAPI template. The extension should work for both Rest and Http APIs.

For even more flexibility you could implement a Lambda authorizer which evaluates the body, but of course this leads to more costs as well:
