  There is no quicker way to kill a high-performance marketing SaaS platform than ignoring gRPC error code 8. You are running a bulk keyword update for a tier-one enterprise client. The job runs smoothly for the first 2,000 operations, then suddenly crashes. Your logs are flooded with   RESOURCE_TEMPORARILY_EXHAUSTED . If your recovery strategy is simply "try again immediately," you are actively participating in a Denial of Service (DoS) attack against your own integration.

This article dissects why Google throws this error, how to architect a resilience layer using exponential backoff with jitter, and when to switch from standard mutations to the  BatchJobService . The Root Cause: gRPC Code 8 and System Overload To fix the error, you must understand the architecture of the Google Ads API. It relies on gRPC, a high-performance RPC framework.

If you are encountering this strict 7-day expiration, your code is likely fine. The issue lies in your Google Cloud Project configuration.

The Root Cause: Google Cloud "Testing" Status The behavior you are experiencing is not a bug; it is a security feature enforced by the Google Identity Platform. When you create a new OAuth 2.0 Client ID in the...
