Using Ready API for sending messages to Amazon SQS Queue (AWS)
If I overwrite de headers manually in ReadyAPI with the ones from Postman (and take the same time and signature) then I can also do the call with ReadyAPI.
But for automated tests this is not really a solution. The signature is not calculated correctly so we need a solution for that problem.
Ou develop team is now looking to work around it with API Gateway, but it would be nice if it worked "right-out-the-box".
