How to prepopulate products via URL Parameters

What about my products section.. quantities...

Unfortunately, only Basic fields can be filled using URL Parameters. Widgets and Payment elements don't allow for prefilling.

If you need to use prefilling on your products, you might employ basic fields for them and later pass the value to a payment element.

I hope that helps.

Yes i am down with any workaroudn, however what is the rule to calculate the product inside  a bisic filed ? all i can copy is the totat.

Bottom like am trying to separate products from address since i want to allow auto fill on adress only

If you wan to separate products from address, you can create:

1). Address field

2). Checkbox, Radio button or Dropdown field for product options.

3). Pass the total value to a form calculation field

4). Assign the form calculation field to your payment field

This is the products am talking about 

You would have to use the basic fields to be able to use the URL parameter.

However, you will not be able to use the quantity field. You would have to separate it as a number field or dropdown.

Then you may assign values or manually calculate the total using the form calculation widget.
