AmzonIntegrator9 Hi,
I am Trying to generate Signature version 4 for Amazon dynamoDB ,
trying to put an item in to table but getting signature mismach error, can any once help on this,
I followed the Amazon documentation but still facing the issue.
Thanks in advance.
Signing AWS requests is very tricky, and you have to follow the instructions EXACTLY. Even then, the error message you get might not give you much detail about where the signature failed. If you've tried following these intructions http://docs.aws.amazon.com/general/latest/gr/signature-version-4.html and still get an error, you should probably post to their forum. Or, better yet, use one of their SDKs http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/UsingAWSSDK.html to handle the signing for you. That's the easiest way.
