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,
Rate Limits and
System Limits guides.
Let us know if you have further questions.

Google Ads API Team
