Resilient backends
Ready-made payments and identity sandboxes with realistic scenarios and failure modes.
Get started
Resilient backends overviewWhat a resilient backend is: your own copy of a provider's API, with the same paths and responses, the failures their sandbox will not give you, and no shared vendor account. Payments and identity are available today.Updated Aug 31, 2026Add providersHow to add payment or identity providers to your organization: what a brand covers, how an order works, the free trial per type, and what removing one does to your sandboxes.Updated Aug 31, 2026Create a sandboxCreate a resilient-backend sandbox: what you need first, the three fields, picking which providers it serves, deploying it, and the URL your integration calls.Updated Aug 31, 2026
Payments
Payments sandbox overviewWhat a payments sandbox does: the whole payment lifecycle with state, 3D Secure your tests can complete, hosted and redirect methods, idempotency keys, and the PSP's own response shapes.Updated Aug 31, 2026Payment scenariosDrive a payments sandbox by naming the payment: every decline reason, the 3D Secure triggers, what to use when there is no cardholder, and which trigger wins when several match.Updated Aug 31, 2026
Identity
Identity sandbox overviewWhat an identity sandbox does: subjects, documents, cases and the checks inside them, KYC and KYB in one API, hosted captures your tests can finish, and the provider's own report shapes.Updated Aug 31, 2026Identity scenariosDrive an identity sandbox by naming the subject: every refusal reason, the review, pending and hosted outcomes, what reaches a subject you did not name, and which trigger wins.Updated Aug 31, 2026
Operate
Write your own scenariosAdd scenarios of your own to a sandbox: where they live, which layer wins, the editor and the YAML behind it, what is validated before a save, and how to scope one.Updated Aug 31, 2026Change values with contextsReplace the values a sandbox returns: what a context is, when you need one, how names match at any depth, how scopes stack, and what the sandbox still checks at runtime.Updated Aug 31, 2026Sandbox activityBrowse what a sandbox has done: the lists each type keeps, what the columns show, searching by reference, filtering, one provider at a time, and how long records last.Updated Aug 31, 2026Pin a build versionHold a sandbox on one build instead of following the latest: where the control is, when pinning helps, what a build change adds or drops, and how long a build stays deployable.Updated Aug 31, 2026
