Fail-open

Fail-open means an endpoint returns a soft acknowledgement on an internal failure rather than blocking the caller. Credicorp's consent and enquiries endpoints are fail-open by design.

Definition

A fail-open endpoint prioritises not blocking the user over guaranteeing the write. If storage momentarily fails, it acknowledges rather than erroring, so the visitor's journey is never held up. Credicorp's consent and enquiries endpoints work this way.

In plain terms

Better to let the visitor through than to block them if something glitches.

Why it matters here

It means you cannot rely on the response to confirm a durable write — show your success state on the acknowledgement and do not read the row back. Contrast a fail-closed probe like healthz.
