Hi Zafar,
Thank you for reaching out to us. I see you’re encountering a RateExceededError(Operations Per Day) for Basic Level Access. This happens when you hit 10,000 operations per day or 1,000 requests per day on your developer token. Could I ask if you have other manager accounts or other users using your developer token as well? If multiple users make requests to the API using the same developer token, you might encounter the daily operations limit. If not, could you please send me your SOAP request and response logs where this error occurs?
Thank you,
Bryan, Google Ads API Team
