# 325 source: https://developer.mastercard.com/open-finance-us/documentation/errors/error-codes/325/index.md This error occurs if an API call is made for an account that is currently undergoing data refresh. | Title | Details | |-------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | **Aggregation Status Code** | 325 | | **Remediation Category** | Retry Later | | **HTTP Status** | 500 | | **Error Type** | Account Error | | **Data Connect Alert** | We're unable to establish a connection to your financial institution. Try again later. (325) | | **Error Message** | The account is currently being aggregated. Call the [Get Customer Account](https://developer.mastercard.com/open-finance-us/documentation/api-reference/index.md#GetCustomerAccounts) endpoint periodically to view the account status. The refresh operation is complete when `aggregationStatusCode` is 0 and `aggregationSuccessDate` is greater than or equal to `aggregationAttemptDate`. | | **Common Causes** | This error occurs when a recent request to retrieve latest data coincides with an ongoing data synchronization for the same account. A new refresh cannot be initiated until the current one completes. This is a common scenario when multiple refresh requests are sent in a short period. | | **Troubleshooting Steps** | * **Wait and retry**: Wait for a short period before retrying the request. This gives the current refresh operation time to complete. * **Check account status** : Call the [Get Customer Account](https://developer.mastercard.com/open-finance-us/documentation/api-reference/index.md#GetCustomerAccounts) endpoint periodically to view the account status. When the data refresh process is successfully completed, `aggregationStatusCode` will return value as 0 and `aggregationSuccessDate` will be greater than or equal to the `aggregationAttemptDate`. | | **Data Connect Fix Eligible** | No. | | **Retriable by End User** | No. | | **Access to Latest Data** | You can access the latest data once the data refresh is completed. | [Full Error List](https://developer.mastercard.com/open-finance-us/documentation/errors/error-list/index.md) \| [Account Errors](https://developer.mastercard.com/open-finance-us/documentation/errors/account-errors/index.md)
