Hi Trung,
The
RateExceededError is usually experienced when there are too many requests made to the API in a short period of time. Since the rateScope here is ACCOUNT, it indicates that the limit has been applied when an application makes high number of requests on a single AdWords account and may trigger this error for exceeding that limit.
You'll need to wait for the amount of time specified in the retryAfterSeconds parameter before retrying the request. You can take a look at the error you're receiving by enabling logging and
this guide illustrates on how to enable logging. This said, you can mitigate this error by taking a control of your application by following some of the strategies mentioned
here.
If you continue to have an issue with this, could you provide us the SOAP logs, so we can take a look and assist you further? Please use Reply privately to author option to provide the logs.
Regards,
Bharani, AdWords API Team
