Note that we are using a Development URL (for Drupal 9) which is not the same as our Production URL (Drupal 7).
While in "Test mode" we receive the following in our error log: The credentials supplied in the authorization request are invalid.
While in "Live mode" we receive the following in our error log: This terminal or user id is not permitted to process this transaction type.
Can we only test this module using the Production website's URL?
Please advise. Thank you.

Update: We are now on Drupal 10 and continuing with the transaction test and are still receiving the following error: "The credentials supplied in the authorization request are invalid."
Please advise.
