# Error Remediation Categories
source: https://developer.mastercard.com/open-finance-us/documentation/errors/error-remediation-categories/index.md

Each error code includes a recommended remediation, which is provided in the documentation. These recommendations outline suggested actions you can take when an error is encountered during either the user flow or an aggregation call.

To get the most value from these remediations, we recommend aligning your internal remediation flows with our standardized remediation categories. This means that when an error is returned with remediation category "A," your application should route the user into your corresponding category A remediation flow. This allows your system to reliably handle unexpected or less-frequent errors by leveraging consistent category-level logic.

In addition to implementing the category-based flows, you should also review the [Most Common Errors](https://developer.mastercard.com/open-finance-us/documentation/errors/most-common/index.md) page and build dedicated remediation flows for those specific error codes. These common error codes represent the highest-frequency scenarios and benefit from tailored handling rather than generic category logic. You should also keep track of the most common error codes you encounter, as they may not exactly match the Most Common Errors page.

| Data Connect Fix                                  | Errors that Data Connect Fix can help resolve. **Important:** Data Connect Fix only applies to this category of errors, not to errors in other remediation categories. For more information, see [Using Data Connect Fix](https://developer.mastercard.com/open-finance-us/documentation/products/manage/aggregation-status-codes/index.md#using-data-connect-fix). |
| Retry Later                                       | Errors that are the result of a temporary issue at the financial institution or platform. There is no action that you need to take nor is there any action that you can take. The user must try again at some time in the future after the issue has been resolved by the financial institution.                                                                    |
| Re-Authenticate or Provide Additional information | Errors that require the end user to re-enter their credentials, re-authorize a connection, or provide additional details to proceed.                                                                                                                                                                                                                                |
| Invalid Input                                     | Errors that include malformed data, incorrect app keys, or expired sessions, among other bad input. You need to correct the invalid data for the workflow to continue.                                                                                                                                                                                              |
| Verify Account or Data State                      | Errors that occur when the account or entity referenced no longer exists, cannot be found, or has other issues. You need to verify the identifiers or connections to enable the work flow.                                                                                                                                                                          |
| Report or Escalate for Investigation              | Escalation errors that result from unexpected or unknown system issues where remediation cannot be determined.                                                                                                                                                                                                                                                      |
| Retry Now                                         | Errors due to incorrect input or a technical issue that can be resolved when the user immediately retries the action.                                                                                                                                                                                                                                               |
