Has anyone here tried forwarding requests to a RESTlet through an Amazon API Gateway? I'm building out a proof of concept test that just forwards a request, but eventually would want to queue requests in case hitting concurrency limits. Reason I'm asking, when I send a payload directly to NetSuite it works fine, when I route it through the API Gateway it fails with an INVALID_LOGIN_ATTEMPT. So it's getting through the API Gateway to NetSuite but rejecting what's essentially the same payload.

Well one thing I noticed during my login audit is my login attempt isn't setting a role. Which is a bit odd, since the same call from Postman sets a role and the same request sent from ServiceNow doesn't set one.
