This guide explains how to connect any webhook-based form to Klaviyo using Outfunnel, so every form submission automatically creates a profile and adds the contact to a list in Klaviyo. This integration works with any form tool or platform that supports outbound webhooks.
How to connect Webhook Forms to Klaviyo
1. Go to App Connector. Head to Outfunnel > App Connector and select Webhook Forms as the source and Klaviyo as the destination.
2. Authenticate Klaviyo with your API key.
3. Copy the webhook URL provided by Outfunnel. Add this URL as the webhook endpoint in your form tool or platform. Submit a test form entry so Outfunnel can detect the available fields.
4. Select your Klaviyo list where new profiles should be added.
5. Map the fields. Once Outfunnel has received a test submission, the form fields will be available to map to Klaviyo properties. Email is required as a minimum. If a custom property does not appear, ensure it exists in Klaviyo first then click "Refresh list".
6. Activate the connection. Submit another test entry to confirm the profile appears in your Klaviyo list.
