Go-Live Preparation

Production onboarding is not available yet.

Before a future production integration, merchants should be ready to demonstrate:

  • Secure server-side API key storage.
  • Idempotent bill submission.
  • Consumer consent flow handling.
  • Webhook signature verification.
  • Duplicate event protection.
  • Monitoring for failed webhook deliveries.
  • Clear distinction between sandbox and production configuration.

Do not reuse sandbox credentials in production.

For the sandbox foundation pilot, Sparelane will also confirm the active base URL, issue a merchant-scoped sandbox key, run a read-only /merchant smoke test and verify that cross-tenant resource access returns safe 404 responses before broader scenario testing.
