We are having difficulty trying to create a Service Connector to communicate with the AWS ReST API. We have tried many different ways of coding the complex AWS signing using xQuery, following AWS guidelines here:
Signing and authenticating REST requests - Amazon Simple Storage Service
AWS returns the message:
The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.
I have run an identical request in Postman and it works.
Having spoken to Luc Clement @ Informatica, I believe there is a solution to this that he was keen to share with the community.
We would be very grateful if you could make available an example service connector which properly produces the signature.
