You can find out how to do this under the heading 'Escalating the error to Flinks' below. ### Supported errors We recommend that you set up your configuration to expect and handle the following errors: | **CODE** | **MESSAGE** | **STATUS CODE** | | :------- | :-------------------------------------------------------- | :-------------- | | 401 | Invalid Input | 400 | | 403 | Subscription not found | 403 | | 500 | Internal server error | 500 | | 501 | Subsystem unavailable | 405 | | 503 | Scheduled maintenance | 503 | | 601 | Customer not found | 404 | | 602 | Customer not authorized | 401 | | 701 | Account not found | 404 | | 702 | Invalid start or end date | 400 | | 703 | Invalid date range | 400 | | 704 | Account type not supported | 422 | | 705 | Account is closed | 409 | | 800 | Payee not found | 404 | | 801 | Payee cannot be modified or deleted | 400 | | 802 | Payment not found | 404 | | 1107 | Data not found for request parameters | 404 | | 1203 | Content type not supported | 406 | | 1207 | Too many requests were sent within a short period of time | 429 | ### Common error scenarios To resolve an error, locate the error you are experiencing and complete the recommendations under the **Action** column. #### Consent errors This type of error is caused by an issue with the end user's consent. | **SCENERIO** | **CODE** | **STATUS CODE** | **ACTION** | | :------------------------------------------------------------------------------------------------------ | :------- | :-------------- | :----------------------------------------------------------------------------------------------------------------------------- | | The end user revokes consent, consent has expired, or they have not consented to a specific data scope. | 602 | 401 | If the request fails for all data collection calls, discard the `refresh_token`. The user will be required to authorize again. | #### Transient failures This type of error is caused by a temporary condition and may resolve itself quickly. | **SCENERIO** | **CODE** | **STATUS CODE** | **ACTION** | | :-------------------------------- | :-------- | :-------------- | :-------------------------------------------------------------- | | Too many requests. | 1207 | 422 | Implement an appropriate throttling mechanism. | | An unexpected error has occurred. | 500 / 503 | 500 / 502 / 503 | Implement an appropriate retry mechanism to resend the request. | #### Non Transient failures This type of error is caused by a specific issue that must be addressed. You will continue to see this error until the issue is corrected. | **SCENERIO** | **CODE** | **STATUS CODE** | **ACTION** | | :---------------------------- | :-------------- | :-------------- | :----------------------------------------------------------------------------------------------------------------------------------- | | Invalid input | 401 / 702 / 703 | 400 | The request is malformed. If this occurs while paging, you can assume the data collected up to this point is valid. | | Subscription not found | 403 | 403 | The subscription for a given user was not found. Notify Flinks if you receive this error for all users of a specific Data Recipient. | | Account not found | 701 | 404 | The account was not found. Try again using a different account. | | Account type is not supported | 704 | 422 | The request is not supported for the endpoint, parameters, or account being requested. | | Subsystem unavailable | 501 | 405 | The information you’re requesting is not available for that particular Data Provider. | ### Issues with the access\_token If the `access_token` is expired or invalid, you'll receive a non-standard error (401 or 403 HTTP status code) and a message that looks similar to the following (in this example, the `code` and `debugMessage` field are missing): ```json Json theme={null} { "message": "message" } ``` If you experience this error, fetch a new `access_token` by calling the [*Token*](/api/outbound/endpoints/authorize/token) endpoint and using `refresh_token` as the grant type.

If you are still experiencing issues

If you complete the steps above to receive a new token but continue to experience the same error, it may be consent related. For more information about how to resolve a consent error, see the [*Consent Errors*](/api/outbound/endpoints/fdx/fdx-errors#consent-errors) section. ### Escalating the error to Flinks If you need help to troubleshoot and resolve your error, contact Flinks and provide the following information: * The [*error code*](./fdx-errors#supported-errors) that you're seeking * Actions you've taken to resolve it * The troubleshooting header you received in the response If the `access_token` is expired or invalid, you'll receive a non-standard error (a 401 or 403 HTTP status code) and a message that looks similar to the following: ```json Json theme={null} { "message": "message" } ```
