PathFactory-Marketo Integration


To get the most out of Marketo and PathFactory, you’ll need to set up Marketo’s API. The API allows you to send page view data from PathFactory directly to Marketo. It also helps with visitor identification in certain scenarios.

Once the API is set up, you can set up additional features, such as the form submission API and custom object integration.

If you want to export all available PathFactory data to a data warehouse, PathFactory offers the ability to create Public API keys.
Marketo has a Daily Quota for the number of API calls that can be made to Marketo. The setup below will result in API calls being initiated each time a visitor engages with a PathFactory asset.


In order for the Marketo API Integration to work successfully in PathFactory you must have a custom subdomain. That is, your PathFactory content tracks must live at a subdomain like (not

The Marketo API uses the Marketo Munchkin cookie to track visitors’ engagement on PathFactory tracks. The Munchkin cookie is a first-party cookie, which means it will only serve its intended purpose (to track visitor behaviour) if the domain it belongs to matches the domain where it is being dropped. Since the Munchkin cookie is being dropped on your PathFactory content tracks we need that domain to match the domain of your Marketo instance. This is why we require that customers using the Marketo API have a PathFactory custom subdomain. Marketo’s documentation describes this in more detail.

Set up Marketo API

This section outlines the steps needed to set up the Marketo API connection between PathFactory and Marketo:

  1. Create a LaunchPoint service.
  2. Enable Munchkin.
  3. Connect PathFactory to your Marketo account.

Step 1: Create a LaunchPoint service

  1. In Marketo, create a dedicated API only user, if you do not have one already.
    This is different from your Marketo user/email address.
