Recommendations callback

2 min

Optimizely returns product recommendations in the form of a JavaScript callback method. When the product recommendations are ready, they are passed to this callback function in the form of JSON data.

var PeeriusCallbacks={
      smartRecs:function(jsonData) {
        // implementation ….
      }
    }

The jsonData parameter is a list of recommendation widget elements that have the following properties.

Important You must use postion (not widget) to render recommendations because the position value is consistent and ensures your AB tests will continue working.

If your rendering code refers to widget instead of position, your code will fail to render the recommendations if someone changes the name of the widget.

Name				Description and usage
widget				[String] Name of widget. Use for information only because this varies during A/B testing. To determine where to place a widget on the page, use the position attribute, below.
alias				[String] Alias of the widget. This is used internally by Optimizely Personalization. It should be used for information only.
position				[String] Name of the page position for this widget. This attribute should be used to determine the page position in which to show the widget. It needs to be a unique ID. This value is stable and should be used to reference (rather than widget).
