Create Webhook through Zapier to link to Mailchimp

I have started a Google Ads Campaign. I want to use a 'lead contact form' that is created on Google Ad. They say I need to have a webhook created so I can paste that into my Google Ads lead section. Then all data from the 'lead form' will go to my Mailchimp account.

I have a Zapier account and would like someone to create a webhook so it links to my Mailchimp account. So when the data is placed on the Google Ads 'Lead Form' that data gets stored in Mailchimp.
