Rest api call. What ip address is going ?

I made an api gateway call to aws and I can see my ip address AA in the request in the logs ( x forwarded header)

When I make another call to s3 though I cannot see the logs as it is internal log. But the request is rejected as I have put a condition to accept requests only from.certain ip address AA.

In the requests through postman too I cannot see this.x forwarded header. Wondering how to debug and see this.
