Save an expression to the library

Journey Optimizer allows Admin users to save personalization expressions to the library. These expressions will then be available to all users to build personalization contents.

To save an expression to the library, follow these steps:

  1. In the editor interface, build the expression then click Add to library.


    If the button is not visible, check in the Admin Console that you have the required permissions (see Permissions levels).

  2. In the right pane, enter a title and a description for the expression to help users find it more easily, then click Add.

  3. The expression is added to the library. Users will now be able to use it to build their personalization content.

  • Expressions cannot exceed 200KB.

  • Saved expressions are sorted by creation date: recently added expression will be shown first in the list.

To edit an existing expression, add it to the editor, then modify it according to your needs. Click Add to library to validate the syntax and save the expression.

To delete an expression, click the ellipsis button then click Delete.
