Can REST GET method in API Gateway support a request body? Does API Gateway drop the body?

Question

I saw an earlier question but I have a specific question and some behavior from the server I can't find answers to.

Setup:

I have an API Gateway setup via VPC link. It has a GET method. It goes through a NLB and a ALB to a target EC2 hosting a SAP REST API. I see from the console and the REST spec that body requests for GET is not supported.

**However, what will happen if someone sends a GET request WITH a body to the API gateway? Will API Gateway simply drop the body?**

I presume the "best solution" here is to change it to a POST, if a request body is necessary?

Answer

I'm not 100% sure but I'd assume if you are using a Proxy request it would pass-through.  But as a consumer, if you need a body, POST is the cleanest way and least confusing way for your consumers.

Answer

For GET requests the body payload will be dropped and the backend will receive a blank payload.
However, if you want the body to pass through you can change the Method in VPC Link integration Request to POST while keeping the resource method as GET.
