With 123 Form Builder, you can connect your online form with various payment processors, such as PayPal, Authorize.net, Sisow, SagePay, PayPal Pro, PayPal PayFlow, Stripe, PayU, Braintree, FreshBooks, and PayFast.
You can add a payment processor from the Form Editor. Scroll the left panel to the E-commerce section, select your desired processor from the list and add your account credentials (username, password, API key, as requested).
To accept payments via PayPal, you will need to enter your PayPal email address and your preferred language.
For the Authorize.net integration, you will need your API Login ID and your Transaction Key. All this information is provided when you create your Authorize.net account.
Further, you can choose your desired currency and specify, if needed, the payment recurrence (daily, weekly, monthly, yearly). However, it is important to mention that not all payment processors offer a recurrent payment system. Visit our Payment Gateways Comparison Chart for more details.
If you want to test the way your payment processes work, enable the Use sandbox option. Don’t forget to disable this option before sharing your online form with your customers.
