Hello,

I'm developing an application that uses the Google Ads API, and I'm encountering a 429 error code when I exceed the API limits and quotas. I would like to better understand how these limits are calculated and whether they apply at the application level or the user level.

Thank you for your assistance

Hi,

Thank you for reaching out to the Google Ads API support team.

Regarding your concern, you mentioned that you are encountering the 429 error. As per this document, all of the Google Ads API client libraries use gRPC for generating requests and responses. By default, gRPC has a message size of 4 MB, but our client libraries set the max message size to 64 MB in order to increase efficiency. Requests that violate this limitation will not generate a GoogleAdsError, but will generate a 429 Resource Exhausted gRPC error. You may refer to the list of gRPC error codes and messages.

For more information about this, you may check our API Limits and Quotas guide.

Let us know if you have further questions.

Regards,

Google Ads API Team
