Frequently asked questions

Where is the exact request contract for Intelligent PDF Splitter?
In Flowyn Docs and the OpenAPI document at https://api.flowyn.dev/openapi/v1.yaml. This page shows the request; the docs page lists every field, status value, error, and limit.
Is the operation durable?
Yes. The operation is stored before any work happens and remains a resource with state, attempts, and error context, not an ephemeral request log.
Do failures stay inspectable?
Yes. Every attempt is recorded. Repeated failures with the same fingerprint are also grouped into an Issue.
