PayWise Developer Docs

Build production-grade PayWise integrations with a clear flow:

Developer -> Identity -> Sandbox Console -> API

Sign inGet API keysMake your first call

Start here​

  • Start in Getting Started for auth, environments, errors, idempotency, and rate-limit behavior.
  • Learn Identity for OIDC-lite flow, token model, passkeys, and TOTP fallback.
  • Use Sandbox Console & Access for key management, security posture, and webhook design model.
  • Navigate API Reference from OpenAPI-generated endpoint docs.
  • Integrate checkout flows via E-commerce Integrations.
  • Track updates in Changelog.
Sandbox vs Production

Use sandbox first for endpoint wiring and retry logic. Move to production only after validating idempotency and error-handling paths.
