Step by step guide on PayPal integration

123FormBuilder provides a very simple way to receive payments with your own PayPal form. You will be able to accept donations, orders and subscription fees in no time. Just follow the steps below to set up the PayPal integration for your form.

1. Create your payment form in the editor.

You can use choice fields (single/multiple choice and dropdown lists) to display the products on sale. If you wish to let submitters specify the amount they want to pay, use a Price field or a Number field (numeric validation is necessary and it’s predefined for these two fields). With 123FormBuilder you can also create subscription forms for newsletters and other services.

2. In your Form Editor scroll to the E-Commerce section and select PayPal from as the payment gateway. For quicker access you can also click Settings – Payments.

Next, you have to enter your PayPal email address and choose your preferred language from the dropdown list. Before saving your settings, enable the payment gateway on the top of the box.

Important Note: To test your PayPal integration with 123FormBuilder, you’ll need a sandbox account on PayPal. If you do not have one, go to to create one. Type in the credentials of your sandbox account in the Payment Processors subsection and tick the Sandbox option on the bottom page.

If you want to enable recurrent payment on your PayPal payment form, tick the option Use recurrent payment. If you want to create a donation form, tick the second checkbox – payment represents a donation. Furthermore, the payment summary from your form is sent to PayPal’s order summary page. If you want to remove it from the page, simply uncheck the Detailed invoice box from the PayPal gateway box in Payments. The feature is not available if you use recurrent payment on the form.

Donation forms cannot be set as recurrent, therefore the two options are incompatible and cannot be used together.

3. Set the payment details – choose the currency, assign prices and perform calculations taking into account taxes or discounts, if applied. You can opt for notifications to be sent to the submitter once the transaction is completed.

Once form users select their preferred products and/or services from the PayPal payment form and submit it, they are redirected to PayPal to perform the transaction. After that, they receive the confirmation message you have created.

Do not assign negative values to your fields. Negative values aren’t recognized by PayPal.

If you want to send additional information to the transaction page, enable the Use shipping options and match form fields with PayPal fields in the lightbox that appears on screen. So if your buyers do not own a PayPal account, they will not need to type in their information again. The fields will be pre-filled with the data they submitted on the PayPal payment form.
