In Zapier, create a new Zap and pick Webhooks by Zapier as the trigger.
Choose Catch Hook and copy the custom webhook URL Zapier provides.
Open the form's Connect → Integrations and pick the Make.com sub-tab.
Toggle on Enable Make.com Integration.
Paste the Zapier Catch Hook URL into the Webhook URL field. The label says 'Make.com' but the field accepts any HTTPS webhook URL.
Click Test Webhook to confirm Zapier receives the sample payload.
Save the configuration.
Back in Zapier, complete the trigger setup by running the data structure detection, then build out the rest of the Zap.
