Create checkout
Use mock mode now or real sandbox credentials later.
INTERNAL TECHNICAL DEMONSTRATION
One payment model.
Two BNPL providers.
A source-backed implementation lab for checkout, retail links, callbacks, payment operations, failure paths, and provider-status checks.
What this proves
The standard integration can be built from the published API documentation. This public deployment simulates the documented contracts; provider credentials and go-live approval remain external gates.
1Documented contractRequest fields, endpoints, states, and sources are mapped.
2Runnable simulationSuccess, rejection, cancel, expiry, capture, and refund are testable here.
3Provider proof pendingReal sandbox calls require provider-issued credentials and account settings.
02
Provider controls
Register server callbacks when using real sandboxes.
Public callback base
—
Use a public HTTPS tunnel for real provider webhooks. Localhost is sufficient for mock mode.

Webhook + status check
03
Payment ledger
Each trace connects the documented provider operation to its sanitized request, provider response, normalized internal status, system action, redirect or webhook, and official source.
No sandbox payments yet
Create a checkout session to begin the demonstration.
04
Webhook audit
Persisted intake records demonstrate duplicate detection and processing outcomes.
No webhook events received.
