Hi Abid,
Thanks for reaching out to us. I see that the error you’ve encountered is a
rate limit type error under the ‘Developer’ scope. Every Google Ads manager account signed up to use AdWords API has a single developer token, and every request you make is most likely associated with that developer token. If the combined QPS for all client requests using the same developer developer token exceeds a certain rate limit, then you will encounter this error. Could you please recheck if anyone else is using this token to make the API calls? If you're still receiving this error, could you please share the complete
API SOAP logs using
Reply privately to author option to investigate further?
Regards,
Bharani, Google Ads API Team
