API functions.
The public merchant API, from its OpenAPI specification. Search, copy a request and run the open reference endpoint.
Making authenticated calls.
Authenticated calls must be made from your own server, because browsers are not permitted to call them cross-origin. Use a sandbox key while you build.
- Bearer authentication with an olp_test_ or olp_live_ key.
- Each endpoint needs the scope shown against it.
- Send an Idempotency-Key when you create resources.
- Sandbox keys never move real money.
