How to integrate to Authorize.net

I added our Authorize.net account but then it started to ask me to add product????

I don't understand.

When using payment field like Authorize.net, the default payment type is SELL PRODUCTS. So that is correct.

You can follow the steps on the user guide. It should be the same even for Authorize.net payment integration.

I hope this help. Let us know if you need further assistance.

I want the "Grand Total" that is calculated from the form to populate the "USD" amount, that way the user does not have to fill that in. 

Is it possible to do that? 

There is a place under Authorize.net Integration where is says, "Get Price From" but it only lets us select "None (Manual)"

Can we some how get this to pull the amount from the "Grand Total"?

You can achieve this using the Calculation widget and custom payment option. Follow the steps on the user guide :

1. Add a Form Calculation widget on your form.

2. The Payment Type should be User Defined Amount

3. Point the "Get Price From" to use the calculation widget.
