Lesson 3 of Open Banking APIs: Test Monitor Repeat

Open Banking API quality is not a one-time certification — it requires continuous verification. APIs that pass testing at deployment can drift over time as infrastructure changes, third-party dependencies evolve, and traffic patterns shift.

This third instalment of APIContext's Open Banking series focuses on the test-monitor-repeat cycle: what it looks like in practice, how to set it up without heavy overhead, and why continuous measurement is the only reliable source of API truth.
