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

Error remediation categories describe the action to take when an error occurs during a customer flow or an aggregation request.

Align your error-handling flows with these categories so that errors requiring the same response follow consistent remediation. This is particularly useful for less common errors that do not require code-specific handling.

Review [Most Common Error Codes](https://developer.mastercard.com/open-finance-au/documentation/errors/most-common/index.md) and implement the code-specific guidance on that page before applying the general categories below. Monitor the errors returned by your integration so you can tailor handling to your customers and use cases.

|                     Category                      |                                                                                     Description and guidance                                                                                      |
|---------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Retry Later                                       | A temporary issue at the financial institution or within the platform prevents the request from completing. Wait before retrying. Follow any code-specific retry interval or escalation guidance. |
| Re-Authenticate or Provide Additional Information | Ask the customer to re-authenticate, authorise the connection again or provide additional information before continuing.                                                                          |
| Invalid Input                                     | Correct malformed data, missing or incorrect headers, invalid application credentials, or other request input before trying again.                                                                |
| Verify Account or Data State                      | Verify that referenced customers, accounts, identifiers and connections exist and are in the required state before continuing.                                                                    |
| Report or Escalate for Investigation              | Report an unexpected or unclassified issue when the documented remediation does not resolve it. Include relevant request and response details in the support case.                                |
| Data Connect Fix                                  | Use Data Connect Fix only when the error documentation assigns this category. Do not use it for errors in other categories.                                                                       |
| Customer Try Again Now                            | Ask the customer to retry the action immediately when the error is expected to resolve on a new attempt.                                                                                          |
