Trigger tag only once in lifetime

Data collection and tags
1

Hi.
I’m doing AB-testing and wish to have a tag fire only once in lifetime, instead of every time the user visits a page where the AB-test is active. Coming from Matomo tag manager there’s an option for this. But I can’t find it in PiwikPro.

/edit: Or as an alternative have it trigger max once per day/week

Thanks!

Hi. To achieve that you would have to use custom async tag and create a cookie or entry in the local storage when the tag is fired. Keep in mind that some of the browsers limit the max lifetime for those, so being able to fire it once in lifetime seems hard to achieve.

After the cookie is set, you could read it using the Cookie variable and then use as trigger condition.
