Sometimes you might want to give your customers different payment options on your form. You can do this using Submit Actions and Routing Logic. First, create a radio button/dropdown list field on your form that contains the payment options you would like to provide.
Some of the options you could include: PayPal, Check, and Bring Cash to the Event. Make sure you make this question required, or the user might skip this question by accident.
In your form, go to Settings > Emails & Actions > Submission Message.
In this example, a Custom message for when the end user selects the check and the Default Message when using cash. Logic can be based on a Radio Button, Checkbox, Dropdown List, Event Fields, or Number fields.
To add Routing Logic to a PayPal integration(or any payment integration), click on the plus sign next to Advanced Settings > select the integration > Logic.
