I am trying to connect SFDC with aws Dynamodb from last few days using query string parameter but not able to generate signature correctly. I have followed steps mentioned in amazon document still I am getting below response:
<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.</Message>
It seems either some of the parameters I am not using correctly or missing few items. I tried code/steps mentioned shared by one of the post mentioned by sfdcfox in AWS Signature (version 4) in Apex. With this I am successfully able to connect with S3 but while chaning parameters for dynamodb, I am facing issues.
Can someone help me on this?
