If configured, the Toast platform prompts the restaurant employee for a gratuity after the Toast platform receives a response from the PMS provider about the discounts and payments redemption.


Gratuity functionality is configurable through the Toast administration back-end. Toast recommends that partners utilize the gratuity transaction to consume all tips related to tender payments. Partners that do so should ignore non-zero values in the tipAmount field contained within the redeem transaction.

Gratuity workflow

  1. After an employee enters a gratuity amount, the Toast POS system sends a TENDER_GRATUITY request that specifies a gratuity amount to add to a TENDER_REDEEM transaction. The Toast-Transaction-GUID of TENDER_REDEEM to add the gratuity amount is provided in the transactionToUpdate value in the body of the TENDER_GRATUITY request.

  2. The PMS provider responds to the Toast platform with a gratuityResponse value in the TransactionResponseGratuity object, which contains the value of gratuity that the guest added.
