| **Common Causes**             | An invalid token can be triggered by various user behaviors or by expiration of a user's data sharing authorization. See the [Customer Authorization Details API](https://developer.mastercard.com/open-finance-au/documentation/api-reference/index.md#getCustomerAuthorizationDetails) for information about the authorization period for any specific user. Users might proactively or inadvertently revoke access to their accounts through use of online banking portals, by updating their passwords, or by adding their accounts to a given application multiple times.                                                                                                                              |
| **Troubleshooting Steps**     | Most OAuth banks are following OIDC and OAuth 2 standards, with a 1:1:1 relationship between the user loginId, Client Application, and token. This means that the same user cannot add their login twice to the same application. If a user attempts to authorize data sharing on a client application with an existing token, the newly issued token will invalidate any other existing token associated with the same client application. To resolve this issue, the end user should re-authorize their data sharing using Data Connect or Data Connect Fix.                                                                                                                                              |
| **Data Connect Fix Eligible** | * [Data Connect Fix](https://developer.mastercard.com/open-finance-au/documentation/connect/generate-2-connect-url-apis/index.md) flow can be leveraged to enable your end users to re-authenticate. This is a separate integration. To know more about [Data Connect Fix](https://developer.mastercard.com/open-finance-au/documentation/connect/generate-2-connect-url-apis/index.md), contact your account management representative. * If Data Connect Fix is already integrated, then try a refresh request. * If refresh request fails to address the issue, submit a [support ticket](https://developer.mastercard.com/open-finance-au/documentation/support/index.md#create-a-support-case-in-scm). |
| **Retriable by End User**     | Yes, the end user can reauthenticate if Data Connect Fix is integrated by the client.​                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      |
| **Access to Latest Data**     | You will be unable to access the latest data for this user's account until the end user resolves the issue.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 |
