Monitoring OAuth 2.0 Client Credentials Flows in Web APIs
OAuth 2.0 client credentials flows are a core mechanism for machine-to-machine API authentication. They enable background jobs, microservices, and system integrations to securely access APIs without user interaction. However, while most teams spend time configuring these flows, far fewer ensure they are continuously monitored in production. This creates a critical blind spot: OAuth failures often surface only after dependent services begin failing.
