How do I add Tip in the Payment Integration?

How do I add a section for voluntarily adding adjustable tip to my digital menu?

Hi @Li_Eddie,

I can see that you are using a Purchase Order tool to sell products and collect payments. There are two ways on how you can collect Gratuity/Tip from your customers.

1. You can simply add a new product and put "Tip" as a description. However, the amount is fixed:

2. User-defined Tip it is not possible through the usual setup through the payment integration wizard.

Instead, you would need to capture the price through your form fields and then send the price to the payment integration to make the charge. Here's a workaround I came up with:

Use Multiple Choice fields for your products then assign calculation values for each option:

After that, we'll add a Number field for the tip and a Form Calculation widget to calculate the options that the user has chosen. Here's a guide on How-to-Perform-Form-Calculation-Using-a-Widget.

We'll then pass the Form Calculation's value to the Purchase Order tool. Please refer to this guide on How-to-Pass-a-Calculation-to-a-Payment-Field. 

I have cloned your form to implement this workaround. Feel free to test this form:
