Retrieve discounts

After an employee selects a guest from the search results on the Toast POS device, the Toast platform retrieves discounts from the PMS provider.

Retrieve discounts workflow

  1. The Toast platform sends a TENDER_RETRIEVE_DISCOUNTS request to the PMS provider. The request includes a TenderTransaction object that holds the guest identifier (tenderIdentifier) and check (Check) in a discountsTransactionInformation object.

  2. Your PMS integration determines the discounts to be applied to the check and responds to the Toast platform with a discountsResponse value in the TenderTransactionResponse object. Discount information is contained in this object. Note that the number of discounts can be zero.

  3. The Toast platform applies the discounts and adds or updates the appliedDiscounts value of the Check object.


    As a provider, you might not support discounts for your restaurant. In this case, you can return an empty array in your response to the TENDER_RETRIEVE_DISCOUNTS request.
