Hi Samuel,
The standard access allows the developer token to execute an unlimited number of operations and report requests per day. If the same application makes a high number of requests per second on a single Google Ads account managed by a manager account, the AdWords API Server may return a RateExceededError for exceeding rate limit within the Account scope. You could refer to
this best practice guide to implement batch job. Also, please refer to
this take control guide to avoid rate limit errors. You can refer to
this sample batch job code to add the campaign.
If you are facing any rate limit error, please share the request and response logs so that I can assist you further. You can use 'Reply privately to author' option while responding.
Thanks,
Milind, AdWords API Team
