Payment Processors

With 123FormBuilder, you can connect your online form with various payment processors, such as PayPal,, Sisow, Opayo, PayPal Pro, PayPal PayFlow, Stripe, PayU, Braintree, FreshBooks, and PayFast.

You can add a payment processor by navigating to the Payments section. Depending on your needs, select your desired processor from the list and add your account credentials (username, password, API key, as requested).

Examples of setup

In order to have a payment processor working correctly, you have to assign prices to fields to your form.

Let’s take an example. We’ve created a form with 2 product fields. All you have to do is assign a price to each of the product fields by going to Payments & Calculations and giving it a price.

For single/multiple choice field, you can follow the same actions: go to Payments & Calculations section and open up the Price modal. For each choice, you can now add its price and click on Save.

After adding prices to your fields/options, you can see an informative banner above your form. All you need to do now is to add a payment processor on your form.

To accept payments via PayPal, you will need to enter your PayPal email address and your preferred language.

For the integration, you will need your API Login ID and your Transaction Key. All this information is provided when you create your 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.

Sandbox testing

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.

Respondent’s experience

Once you have added and enabled your payment processor on the form, you will notice some changes.

An order summary is displayed on the form. Here there will be displayed all the products/choices that your respondents choose and have a price assigned.

The Submit button is changed to Continue to payment – this is to help respondents understand that a payment will be performed. Thus, you are increasing your chances of having a complete submission with a successful payment.

Below the Continue to payment button, respondents can see what payment processor is used for making the payment. In our example, we have PayPal – and below the disclaimer that is meant to give respondents confidence into your form, they can see the accepted cards for making the payment.
