Set Up Webhooks

Webhooks collect data when your list changes, and can then send updates to an application outside of MailChimp.

For example, you might set up a webhook to notify your CRM system when events like subscribes, unsubscribes, and profile changes happened in your MailChimp list.

In this article, you'll learn how to set up webhooks.

Before You Start

Here are some things to know before you start this process.

  • This is an advanced feature and is recommended for users familiar with custom coding. Contact your developer, or hire a MailChimp Expert if you need assistance.
  • You or your developer will need to set up a callback URL in your application or integration to deliver webhook requests to.
  • To preview what different types of webhook events will look like after they're triggered, create a test URL with Beeceptor or Mockbin.
  • Learn about example webhook requests and responses in our API Docs.
