Payclave API documentation

Build hosted stablecoin checkout with Payclave checkout sessions, invoices, independently verified payment records, and signed webhooks. Start with the HTTP reference, then use a test secret key from your merchant backend to create a checkout session. Keep test and live credentials separate.

Payclave authentication and API contracts

The API uses versioned /v1 paths at https://api.payclave.com. Read the authentication guide for secret and publishable keys. The OpenAPI specification describes the eight core integration operations with typed requests, responses, errors, and unique operation IDs; the full HTTP reference also covers additional merchant operations.
