# Retry Double Check

> <Note>This content applies to WaaS 1.0 only. We highly recommend that you upgrade to [WaaS 2.0](https://www.cobo.com/developers/v2/guides/overview/introduction).</Note> This endpoint retries a double check for a withdraw request with the given request_id. The request must be a POST request and the user must have all permissions. The endpoint retrieves the withdraw request with the given request_id and checks if it exists and has a status of 'STATUS_WAITING_DOUBLE_CHECK'. If the request is valid, the endpoint locks the record and processes the withdraw request with the 'process_waiting_double_check_withdraw_request' method from the CustodyService class.

<ResponseField name="result" type="object">success is null. </ResponseField>
