We recently discovered something that would be beneficial to have known from the online documentation for Event Triggers.

The online documentation says to create a new event trigger from the D365 Marketing app & then provide the developer with information.

Instead, our developer created the event trigger on the backend. After he created the trigger and marked it 'Ready for Use' - we saw the trigger appear in our Event Triggers list in D365 Marketing (Great/no problem). We also saw the Event Trigger available for selection when we created a New Journey (Great/no problem).

The issue is when we tried to update our RT Email with the new Trigger. The new trigger did not appear - despite showing in all other areas. We found that it just took time. We had to wait about 10-15 minutes and the new event trigger finally appeared as an option in the email for personalization.

I think it would help others to know that 1. You can created event triggers from the backend and 2. It could take 10-15 minutes before you can see it in email.

Here is the online documentation that I am referring to: Custom event triggers in real-time marketing (Dynamics 365 Marketing) | Microsoft Docs
