The following two sections show a workflow where the promotion is valid, and three workflows where the promotion is invalid, removed, or ineligible.

  • Promotion Is Valid

  • Promotion Is Removed or Invalid

Promotion Is Valid

The following is the workflow for a promotion that is successfully applied and redeemed by the provider.

  1. The promotion is successfully applied.

    1. The server first selects the Discnt button at the bottom of the Order screen.

    2. The server selects the configured Promotions button.

    3. The server enters a valid promotion code and clicks the Apply Code button.

    This action sends a PROMOTION_VERIFY request via the promotions API to the provider. If the request is valid, the API will return a PromotionObjectobject.

  2. The promotion is revalidated before payment:

    Toast verifies that the promotion is still eligible when the server selects the Send, Stay, Hold, or Pay button on the Order screen. The Toast POS system indicates this action by displaying a progress spinner and a Validating Discounts message to the Toast POS user. In this example, the 50% Holiday Discount promotion is validated.

    This action sends a PROMOTION_REVALIDATE request via the promotions API to the provider. If the promotion is still valid, the API will return a 200 response and a list of AppliedPromotion objects.

  3. Check with promotion is paid.

    Upon the completion of payment, the promotion is redeemed by the provider.

    This action sends a PROMOTION_APPLY request via the promotions API to the provider. If the promotion is successfully redeemed by the provider, the API will send a 200 response and a list of AppliedPromotion objects. If the promotion fails to be redeemed for whatever reason, the API will return a 400 response and the appropriate ErrorResponse object.

Promotion Is Removed or Invalid

The following scenarios occur when the promotion is not eligible for promotion, invalid, or removed:

  • Check is not eligible for promotion:

    If a promotion is not valid, an error message (such as The promotion code is invalid) displays on the Toast POS after you select Apply Code.

    This action sends a PROMOTION_VERIFY request via the promotions API to the provider. In case of an invalid promotion, the API will return a 400 response with an appropriate ErrorResponse object. This contains a PromotionError object where an ErrorType can be specified as well as a userErrorMessage to be displayed for the Toast POS user.

  • Promotion is no longer valid upon revalidation:

    Toast verifies that the promotion is still eligible when the server selects the Pay button. The Toast POS system indicates this action by displaying a progress spinner and a Validating Discounts message to the Toast POS user. If the promotion is not valid, an error message (such as The promotion code is invalid.) displays on the Toast POS after you select Apply Code.

    This action sends a PROMOTION_REVALIDATE request via the promotions API to the provider. If the promotion is invalid based on the new state of the check, the API will return a 400 response and the appropriate ErrorResponse object.

  • Promotion is removed:

To remove a promotion (regardless of whether it has been redeemed yet or not), you highlight the promotion in the Order screen and deselect the discount button that displays the name of the promotion that you would like to remove.

Once the promotion is removed and you have navigated away from the discounts screen, the button of the removed promotion will no longer appear.

This action sends a PROMOTION_VOID request via the promotions API to the provider.
