About the Expression Editor

The Expression Editor is the centerpiece of the personalization in Journey Optimizer. It is available in every context where you need to define personalization like emails, push and offers.

In the expression editor interface, you will select, arrange, customize and validate all the data to create a customized personalization for your content.

The left part of the screen displays a domain selector that lets you select the source for personalization.

Available sources are:

  • Profile attributes : lists all the references associated to the profile schema described in Adobe Experience Platform Data Model (XDM) documentation.
  • Segment memberships : lists all the segments created in Adobe Experience Platform Segmentation service. More information on segmentation available here.
  • Offer decisions : lists all the offers associated to a specific placement. Select the placement then insert the offers in your content. For a complete documentation on how to manage offers, refer to this section.
  • Contextual attributes : when the Message is used in a journey, contextual journey fields are available through this menu. Learn more in this section.
  • Helper functions : lists all the helper functions available to perform operations on data, such as calculations, data formatting or conversions, conditions, and manipulate them in the context of personalization. Learn more in this section.

Click the + button too add an attribute into the editor.

NOTE

The ellipse menu next to “+” icon allows you to get more details for each variable and to add your most frequency used attributes to favorites.

In the following example, the expression editor lets you select the profiles that have their birthday today then complete the customization by inserting a specific offer corresponding to this day.

Once your personalization expression is ready, you need to have it validated by the Expression Editor. Learn more in this section.
