Yes, you can. 123FormBuilder is an Authorize.net certified solution. This means you can trust our services when receiving money in your Authorize.net account from your clients through form submissions.
To integrate your online order form with your Authorize.net payment gateway, go to Settings → Payments, in the Payment Processors section, select Authorize.net from Payment gateway and hit Add payment gateway to enable the integration with this payment processor. Two new fields will pop up in a box below: API Login ID and Transaction Key. Type in your Authorize.net information, enable the processor on the top right corner of the box and click Save.
Tick the option Create a Customer Information Profile (CIM) if you want to save client profiles in your Authorize.net account based on the submitted credit card number from the first purchase. When a form user submits an order for the first time, a profile will be created in Authorize.net with the payment and shipping information. The shipping information may be changed each time the form user submits another order on your form.
To retrieve either one of your authentication data, follow the steps below:
1. Log in to your Authorize.net account.
2. Go to Account → Security Settings section and go to API Credentials and Keys. Here, you can copy the Login ID and Transaction Key that you require back in 123FormBuilder.
