APIG.0201 Error

If the error message "Backend timeout." and error code "APIG.0201" are displayed when you call an API, the request timed out.

Perform the following steps to rectify the fault:

Use a tool, such as Postman, to call the service and check whether the call is successful. If the call is successful, the service API is normal. Perform the following steps to proceed:

1. Check whether API call requests are excessively frequent. If there are too many concurrent requests, check the return value in the code and resend the requests later (for example, 2 to 5 seconds later). You can also check whether the result of the previous request is returned at the backend. Do not send a request before a result is returned for the previous request.
2. Check whether the audio file is too large or the network delay is too high. If the audio file is too large, you can compress the audio in MP3 format. If the network delay is too high, improve the network transmission speed.

To avoid this problem, you can call SIS using the SDK provided by the service. For details about how to obtain the SDK, see Obtaining SDKs.

If the above solutions cannot rectify the fault, contact us.
