How to Redirect Users to a Custom URL on Form Submit
Edit your form and go to the Settings panel. Under General you can set a redirect URL, along with a delay period in seconds.
Let's say we have a form field type checkbox with the label Department with possible options being Sales and Technical. Open the Conditional Logic panel and set this logic step:
IF Department contains Sales THEN redirect to http://example.com/sales
You can have both basic and conditional redirect in the same form. Conditional redirect will take precedence over basic redirect.
