If you get the above error message, please Re-Authorize the app. See the link to re-authorize app.
This error may occur due to the following scenarios:
- The user that originally authorised the App has been de-activated
- Salesforce as moved your instance onto a new pod (and in turn a slightly different URL)
- You have another error message that occurred. Please check Payments2Us error log as that may have details on that error message and what it relates to.
- For version prior to 8.12, if you manually added a new Merchant Facility and then made it active after the App was first authorised
- You have created a partial or full sandbox and did not re-authorise the App before first using in that sandbox.
