To be able to use the created events, drag the event element Analytics event to the workspace in the Campaign Builder. Double-click on it to open the configuration. In the trigger event drop-down list, you will find a list of all the events created so far. For a better overview, the domain for which the event applies is now in brackets before the name. Here you can select the desired event. You can then name the event element as usual and link it to other elements.
Note: Please note that a contact can only go through a campaign once, even if they meet the event condition several times.
