Hello @layeeqa As this is a different issue, please create a new thread and provide details of the issue. Authentication issues (unauthorised) are caused either by the credentials being incorrect, request is being submitted to an environment for which the credentials are not valid (using sandbox credentials on a production endpoint, or vice-versa) or you're attempting to submit a transaction request for which you're account is not authorised (payouts in production for example). As I mentioned above, you'll need to create a new thread and provide detailed information about the request you're submitting, including the API response you're receiving back where the error is shown. Thanks !
