Create test key
Open the merchant dashboard and use a test secret key for the first API calls.
No production risk
Prove the checkout flow before real funds move.
Use testnet to validate payment sessions, buyer checkout, public status, webhook delivery, and reconciliation records before mainnet activation.
Create session
Call POST /api/v1/payments with a small amount and test metadata.
Open checkout
Use the returned payment_url and complete the wallet-side testnet flow.
Read status
Call GET /api/v1/payments/{id}/status and store the status plus transaction hash.
Receive webhook
Verify the signature and update your order only after a trusted event.
Review records
Compare session ID, order ID, amount, network, token, and fee records before mainnet review.
Definition of done
Your integration is ready for review when a developer can create a session, open checkout, confirm status, verify a signed webhook, and reconcile the merchant order ID without manual support.
