String to remove tag(s)?

Your software
My Mautic version is: 4.4.7
My PHP version is: 7.4
My Database type and version is: MySQL 5+

I have this string in a web page to add a tag to a contact that lands on it.

<img src="https://www.domain.com/mtracking.gif?email=<? echo $_GET['email'];?>&tags=BTG">

What is the string to remove a tag? I did try adding a minus before the tag and it didn’t work for me.

  • Changed BTG to -BTG
<img src="https://www.domain.com/mtracking.gif?email=<? echo $_GET['email'];?>&tags=-BTG">

Thank you

Did not even know that was possible for adding tags.

One way to remove tags I think is to create a script that remove tags and include it in the link.
