REST API
The dominant API style — resource-oriented HTTP endpoints with JSON payloads — the lingua franca of iGaming integrations.
REST APIs model operations as HTTP verbs on resources (GET /conversions, POST /postbacks), with JSON responses, token auth and pagination conventions.
Integration-practice notes
The conventions that separate pleasant from painful REST: consistent pagination (cursor beats offset at volume), idempotency keys on mutating calls (retries happen; duplicates shouldn’t), meaningful error bodies (not bare 400s), and stable field semantics across versions. GraphQL and event streams appear in the stack’s newer corners, but REST remains the assumed default — an integration team’s fluency in its patterns is baseline capacity, not specialization.
