Hi Mahesh,

&nbsp; &nbsp;Please check your redirect\_uri that you are passing at the time of token generation, the redirect\_uri should be same as that of&nbsp; successful code generation. This will help you fix the token generation error.&nbsp;Please update us&nbsp;if this resolves the issue.

On our end we will have a fix for this error message invalid authorization code by this month end release.&nbsp;

Thanks,

Kavitha
