Provider Fixtures

Provider contracts you can replay before staging.

Provider adapters fail at state transitions, not just at request validation. These catalogs keep scenario, initial state, expected state and webhook behavior together for repeatable tests.

2. Provider contracts

Replay provider-specific payment, mandate, payout and webhook states with source-linked fixtures.

Questions teams ask

Are these payment fixtures connected to real accounts?

No. They are synthetic or sandbox-only fixtures. They are designed for QA, CI and contract tests, not for live payment submission.

Can I export fixtures as JSON or CSV?

Public pages expose a bounded preview. Authenticated paid API and lab workflows can export larger JSON or CSV matrices according to plan limits.

Do the fixtures include expected outcomes?

Yes. Each case includes a scenario, expected status or outcome, relevant error details and a deterministic seed where supported.
