Integrate a restaurant loyalty program using Punchh or Paytronix API patterns to award and redeem points

Steps

1. Apply for API access through your loyalty platform provider (Punchh or Paytronix); both require a partner agreement and are not self-service
2. At checkout, look up the guest's loyalty account by email or phone number using the customer lookup endpoint to retrieve their current points balance
3. After a successful order, post a transaction event to the loyalty platform's earn endpoint with the order total and eligible line items; the platform calculates and credits points according to the active earning rules
4. For redemptions, call the redemption validation endpoint with the guest's requested reward and receive a discount value or coupon code to apply to the current order
5. On order completion, finalize the transaction with the loyalty platform to close the earn/redeem cycle; use the order ID as the idempotency key to prevent double-crediting
