Ask for a rating

Use an input request to ask a shopper for a rating from 0 to 10.

Here we describe how you can use an InputRequest to ask the shopper or your staff to enter a numerical value from 0 to 10. You can use this, for example, to conduct a Net Promoter Score (NPS) survey.

The following illustrations show a rating input screen on a portrait and landscape display.

AMS1 payment terminals cannot support the rating screen due to limited screen-space.

On a small non-android payment terminal portrait display, the information is divided over two screens. The user needs to select Enter rating before entering a value using the keypad.

On a portrait and landscape terminal without keypad, an on-screen keyboard appears.

The terminal continues to show your input request until one of these events occurs:

  • The user has provided input.
  • The maximum input time expires. You can set this time in the request.
  • On the terminal, Cancel is selected.
  • The terminal receives a request to cancel collecting input or any other request from the POS app.

Make a Rating input request

To use the payment terminal to ask for a rating from 0 to 10:

  1. Make a Terminal API input request, specifying:

    • The standard SaleToPOIRequest.MessageHeader object, with MessageClass set to Device and MessageCategory set to Input.

      Parameter Required Description
      ProtocolVersion -white_check_mark- 3.0
      MessageClass -white_check_mark- Device
      MessageCategory -white_check_mark- Input
      MessageType -white_check_mark- Request
      ServiceID -white_check_mark- Your unique ID for this request, consisting of 1-10 alphanumeric characters. Must be unique within the last 48 hours for the terminal (POIID) being used.
      SaleID -white_check_mark- Your unique ID for the system where you send this request from.
      POIID -white_check_mark- The unique ID of the terminal to send this request to. Format: [device model]-[serial number].

    • InputRequest.DisplayOutput: This object defines what is shown on the terminal.

      Parameter Description
      Device CustomerDisplay
      InfoQualify Display
      OutputContent.OutputFormat Text
      OutputContent.PredefinedContent.ReferenceID GetRating
      OutputContent.OutputText An array of one or two Text fields containing your own text to show on the terminal. The first text is shown in bold. Use \n for a new line. Apart from the text you specify, the terminal will show an instruction for how to confirm the input.

    • InputRequest.InputData: This object handles the user input.

      Parameter Description
      Device CustomerInput
      InfoQualify Input
      InputCommand DigitString
      MaxInputTime (Integer) Time-out in seconds. This is the time that the user gets to finish their input.

    The following example asks the shopper for a rating using the first Text field for the core question and the second Text field to explain the scoring.

  2. Wait for the user to supply the requested input.

    The provided input is not validated against a format.

    • If input is received from the terminal, the InputResult.Input contains:
      • DigitInput: the numeral that the user entered.

    • If the input request times out, the InputResult.Response has AdditionalResponse: message=Screen%20timeout, Result: Failure, and ErrorCondition: Cancel,

    • If you make a payment request while the input request is waiting for input on the terminal, the payment request overrides the input request. The InputResult.Response has AdditionalResponse: message=A%20higher%20priority%20request%20has%20been%20received, Result: Failure, and ErrorCondition: Busy.

    • If the user declined to respond (selected the Cancel key ), the InputResult.Input.DigitInput field is empty. The InputResult.Response has Result: Failure and ErrorCondition: Cancel.

  3. Pass the DigitInput value to your system for validation and further use.
