Gratuity

When a customer checks out, Ordering End-to-End displays a tip selector. This lets the customer choose the amount of gratuity to include with their order.

Ordering End-to-End sends the chosen amount in SubmitOrderRequestMessage as a LineItem of type GRATUITY inside a ProposedOrder.otherItem.

How to hide the tip selector

You can hide the tip selector for a restaurant service by using the ServingConfig.disableTipWidget in your inventory data feeds.

How to set a default gratuity amount

You can set a default gratuity amount or refuse to accept gratuity for a restaurant during checkout. The following use cases can be supported in the CheckoutResponseMessage:

• A restaurant requires a fixed gratuity amount

  In the ProposedOrder.otherItems within CheckoutResponseMessage, add a line item of type GRATUITY with a fixed amount inside.

  JSON

  {
    "name": "Required Tip",
    "type": "GRATUITY",
    "price": {
      "type": "ESTIMATE",
      "amount": {
        "currencyCode": "USD",
        "units": "3",
        "nanos": 100000000
      }
    },
    "gratuityExtension": {
      "gratuityType": "MANDATORY"
    }
  }

• A restaurant suggests a gratuity and gives the customer the option to modify the amount

  In the ProposedOrder.otherItems within CheckoutResponseMessage, add a line item of type GRATUITY with a fixed amount. Be sure to also add gratuityExtension with a gratuityType value of USER_MODIFIABLE.

  JSON

  {
    "name": "Suggested Tip",
    "type": "GRATUITY",
    "price": {
      "type": "ESTIMATE",
      "amount": {
        "currencyCode": "USD",
        "units": "3",
        "nanos": 100000000
      }
    },
    "gratuityExtension": {
      "gratuityType": "USER_MODIFIABLE"
    }
  }

• A restaurant doesn't accept any gratuity

  In the ProposedOrder.otherItems within CheckoutResponseMessage, add a line item of type GRATUITY with a blank amount inside.

  JSON

  {
    "name": "Tip",
    "type": "GRATUITY",
    "price": {
        "type":"ESTIMATE",
        "amount": {
          "currencyCode":"USD"
      }
    }
