With 123 Form Builder, you can also create subscription forms for newsletters and other services.

2. In your Form Editor, scroll the left panel to the Payments section and select PayPal as the payment gateway.


3. Next, you have to enter your PayPal email address and choose your preferred language from the dropdown list. Afterward, hit the Enable button to connect your account.

Setting up PayPal

PayPal billing options

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 Use detailed invoice box from the PayPal billing options. The feature is not available if you use recurrent payment on the form.

Important Note

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

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 in the forms Thank you Page section.

If you want to send additional information to the transaction page, enable the Use shipping options and match form fields with PayPal fields. Therefore, if your buyers do not own a PayPal account, they will not need to type in their information again. The fields will be prefilled with the data they submitted on the form.
