Response Codes

All response codes along with their response models are documented in our Swagger documentation . Here you can find some additional context for them.

409 and 423​

In order to ensure better data consistency and reduce errors during request processing, FastAuth implemented two additional error codes:

  • 409 – This occurs when a request sent to the endpoint PATCH /api/external/v1/Requests/{appointmentId} has a different value in the “version” field compared to the request currently stored in the database (this scenario does not apply to adding a new request). The version field should always be provided with the request. If no value is provided, we are unable to check the version of the record, and the request will be automatically rejected.

  • 423 – This occurs when a request sent to the endpoint PATCH /api/external/v1/Requests/{appointmentId} is currently being processed by our system (the IsProcessing field is set to true).

Field: IsProcessing and Version have been added to the model in the External API. The field IsProcessing will be updated to false when all processing is finished. During processing, the value of this field should not change. If something goes wrong during processing and this field isn't toggled immediately, it will be force-toggled by an automated process after 15 minutes (counting from the UpdatedDate).
