php to change form action url for Contact Form 7 in WP

[designnyc]

I'm adding a new form to a WP site that's already been set up with Contact Form 7. The form data needs to be sent to a different .asp than the other forms. I've been searching all over online and closest solution I've found is:

 

change the "action" attribute in the form using this Filter Hook wpcf7_form_action_url. You could add the hook into your theme's functions.php and then just process the form data in your ASP page.

 

How would I need to code the php file to customize the form action url?

Not familiar with php and terms, I'm completely lost and feel it's probably simple solution which I'm unaware of and would appreciate any help.

 

Thanks so much!
