MODx Marketo Integration for the XebiaLabs Website


XebiaLabs uses MODx for its content management system and Marketo for its marketing automation system. To integrate Marketo into MODx I came up with an extremely creative solution that used a custom PHP class to pull Marketo lead data from their SOAP API and then subsequently populate that data into corresponding MODx “placeholder” elements.

First I found a php client for pulling the information from Marketo’s SOAP API, they provide some code here to pull lead data, but I wanted something I could use to pull other information from their API. turns out, someone had already done much of the heavy lifting.

I then coded the below snippet that does the following.

Initially I check to see if I’m specifying a lead manually by passing someone’s email in a query parameter. This is a nice override for when I need to view pages as a specific person within our database. It’s also nice when I need to ensure that someone sees a webpage with their info. I can append the link I have in an email, for example, to include their email, and subsequently ensure they see they website as they should. They may not have a munchkin cookie after all.  If I view a user in this method I store the information in a session so that I don’t have to perpetually communicate with the Marketo API for future pageviews.

If I then view any subsequent page on the website my information gets pulled from the session.

If I don’t have a query parameter specified for a user, and I don’t have any sessions from a previous website visit I use the PHP client to see if their is a munchkin cookie in the user’s browser.

If their is I pull the viewers lead data using their munchkin cookie. Then, as with the query parameter example I store the user’s info in a session variable so that I don’t have to communicate with the API again.

After lead data is stored in a session or pulled directly from the Marketo API I am then able to pass the information to a built in MODx method for displaying information. I use something they call “Placeholders”.

This code is lacking some serious security precautions and error handling. It is being worked on for the future, and I will try to update. Please comment if you would like further direction.
