Login or create a ContactUS.com account. Choose the form you want to integrate with ContactUS.com by clicking on the Forms Panel (1), then click on the form you want to integrate (2)and then click on submission settings (3)
Click on (1) “ Software Integrations ” from the submission settings page and then on the *(2) " Zapier Integration Box " from the Software Integrations Panel.
Paste the Webhook on the Zapier integration Box. Hit the disabled/enabled toggle and set to “ENABLED”.
Once you have saved the integration, go back to Zapier and click continue to progress to Step 3.
