The product ID is a unique ID number assigned to each product in your form builder.
You can use the product ID to load the form with a preselected product from the product list. This is beneficial if you'd like to direct people to a page with a specific product preselected but still offer them the chance to use other products in the same form.
To preselect a specific product from a form, you can pass product ID as a URL parameter like ?dfpr=<ID>
Where <ID> is the product ID taken from DepositFix form builder.
For example, if we want to preselect the 2nd product on this page: https://dfforms.com/shareform/dff21737-2660-40ab-a792-c0120bf1eeba, we can do that by adding the above URL parameter along with the product ID. So the URL will be: https://dfforms.com/shareform/dff21737-2660-40ab-a792-c0120bf1eeba?dfpr=dfpr9fem9P
