Unique Event ID


I have followed your tutorial about the Deduplication: https://gtm-server.com/how-to-set-up-facebook-event-deduplication-in-google-tag-manager/

I have already imported the Unique Event ID template in my Web Container but I can’t find it under the More Settings in Tags.

Here is the image from the blog post.

Let me know where I can find this.

Hi @Falconerie_Badayos_I, go to the Variables tab inside the Web container. Under User-Defined Variables click New and create a Unique event ID variable that you’ve imported.

You can’t see it because the variable was not added to your workspace. Thanks for the question, we will update the post to make it more clear.

Thank you, this worked like a charm!

Hi, I also followed the directions and was able to import template and create a variable.

However, when testing, I see that the “number” is not being generated. So it just shows the name of the variable. Any idea how to fix this?


@school You need to toggle “Display Variables” settings in the GTM debugger. And then, you will see the variable value.
