JavaScript API Integration

Recommended reading 

This section describes the JavaScript API integration method used for integrating Optimizely personalization features.


To set up the Optimizely personalization, you need to provide Optimizely with a product catalog feed. See Catalog feed specification.

How it works

The JavaScript API consists of two independent components:

  • JSON tracking

    To get the best recommendations from the algorithms, track all pages relevant to a customer’s purchasing experience on your site. JSON tracking lets clients provide user journey and user details to Optimizely. By doing this, clients can control how and when a given page on their website is tracked.

  • JSON recommendations

    Optimizely provides the most relevant refCodes for product recommendations (either refCode only or full details). Then, the JSON Recommendations function lets clients control the precise design, information display, and positioning of the Recommendations widgets displayed on their web pages.

When developing using the JavaScript API, you must set up a test site that references the Optimizely Staging environment before going live. Contact Optimizely client services to whitelist your site in our UAT environment.

Note: You cannot provide personalized recommendations on UAT because behavior is gathered in the live environment. However, you can deploy recommendations live under SPR (See Recommendations) prior to full release for review.
