API Reference
Syncra Merchant API V2 reference: 29 endpoints and 14 webhook event types — each on its own page with request and response schemas and an interactive Try-it panel.
This reference is auto-generated: the pages are built from openapi.yaml — the official OpenAPI specification of Merchant API V2 — and update on every spec change. Descriptions, parameters and response codes here always match the live API.
The "Test" button opens an interactive panel: requests go to the staging api-stage.syncra.money with your staging merchant's test keys (the HMAC-SHA256 signature is inserted ready-made — see Authentication for how it is computed). For production requests, copy the ready curl snippet and run it from your own code.
