CF-7 and Pardot integration.

Hello guys,

I am new to WordPress. I am working on integrating WordPress form data to Pardot.
I followed this link to integrate the CF-7 form with the Salesforce Pardot. https://www.digitalmenta.com/en/inbound-marketing/how-to-integrate-pardot-forms-into-wordpress/
I used the #4 method: Connection between Contact Form 7 and Pardot Form Handlers

Now I don’t see any network call happening when I submit data and at the same time I don’t see any data posting in Pardot. Can any one help me with this is the issue how to debug.

Thanks in advance
