This guide explains how to connect any webhook-based form to Mailchimp using Outfunnel, so every form submission automatically adds the contact as a subscriber in your Mailchimp audience. This integration works with any form tool or platform that supports outbound webhooks.
How to connect Webhook Forms to Mailchimp
1. Go to App Connector. Head to Outfunnel > App Connector and select Webhook Forms as the source and Mailchimp as the destination.
2. Authenticate Mailchimp via OAuth.
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 Mailchimp audience where new subscribers should be added.
5. Map the fields. Once Outfunnel has received a test submission, the form fields will be available to map to Mailchimp fields. Email is required as a minimum. If a custom Mailchimp field does not appear, create it in Mailchimp first then click "Refresh list".
6. Activate the connection. Submit another test entry to confirm the subscriber appears in your Mailchimp audience.
