The flow
- Start: POST /v2/register returns a live key and a test key (mk_test_…) that settles through a simulator, with fake money.
- Safe retries: every checkout takes an Idempotency-Key, so a retried request returns the same checkout.
- Settle: signed webhooks (X-WavePay-Signature) or the payments ledger with since/limit cursors.
- Reference: /openapi.json, /docs.html, /skill.md and /llms.txt describe every route.
Questions
Is there a sandbox?
Yes. The test key uses the same routes with fake money and never reaches a provider or counts against your plan.
Where is the API reference?
openapi.json, docs.html and skill.md, all generated from the same source as the Worker.
