I already built a tool in google apps script which works well with APIs associated with MWS. I am now working to build similar on NodeJs. But now I am trying to post URL but getting this error
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 checked signature and is generated properly, I took url from mws scratchpad and tried it on browser. Even it throws the same error while it gave proper valid response at scratchpad.
I also tried generating URL from my previous running project which is giving proper responses, pasted them in browser’s address bar, and here also it is giving the same error.
What could be the reasons for this?
