Who this section is for

Partners and backends can receive HTTPS callbacks from HG.Cash. HG.Cash sends POST requests with JSON when ledger transactions change or transaction requests (such as outbound / cash-out transfers) transition state. Optionally verify deliveries with HMAC-SHA256. Work with HG.Cash onboarding for URLs, signing secrets, and sandbox vs production endpoints.
