Conventions
How every API here behaves.
These hold across the catalogue, so once you have integrated one API the next one is familiar.
| Style | REST over HTTPS, with predictable JSON responses |
|---|---|
| Environments | Sandbox and production, with separate credentials for each |
| Asynchronous events | Webhooks to an HTTPS endpoint you provide |
| Every transaction | Carries a unique reference ID, through to settlement |
| Failures | Retried where the network allows, then returned as a clear status rather than left pending |
| Tooling | SDK samples and code examples, shared during integration |
| Availability | Enterprise-grade uptime SLA |
The details behind these — how errors look, and how to learn a transaction's final result — are in Status & Error Codes and Webhooks & Transaction Status.
