The RGS calls your backend to debit or credit the player's balance when bets and wins occur. You must implement four callback endpoints: debit, credit, balance, and rollback.

All callbacks are HMAC-signed (X-Timestamp + X-HMAC-SHA256 headers). Use transactionId as the idempotency key for deduplication.

For request/response schemas, status codes, idempotency details, and verification examples, see the Callbacks Guide.
