can someone explain to me what "Applicability condition" is and how it works?
This is our scenario.
I extended the Delivery schema with some new fields (eg. utm_source).
Then I set these new fields as parameters in "Tracking URL configuration" in Brand Configuration settings.
In this way, when I create a new delivery, I can specifiy a fixed value for each of these new fields, for example utm_source = test. Campaign will automatically add these fields to any links (eg. www.test.com?utm_source=test ).
If I leave these fields empty, Campaign will automatically add just fields name to each link (eg. www.test.com?utm_source=) .
I need to understand if there is a way to set a condition like this:
if the field is NOT empty, then Campaign will add this field to each link
I I need this kind of condition because in some cases I haven't a fixed value, I need to use a dynamic value, for example the current date (eg. utm_source=20200714 for today, utm_source=20200715 for tomorrow and so on). In these cases, I set the utm_source directly in the HTML using a content block.
Without a condition like the one specified above, if the field is empty and I set the utm directly in the HTML, the URL will have two utm_source: the one specified in the HTML and the one of the Brand Configuration setting (eg. www.test.com?utm_source=20200714&utm_source= )
I suppose that I can use "Applicability condition" to set this logic, but I don't understand how to set it (I tried IS NOT NULL condition but it didn't work).
I understand it has been long since you posted this query, but would you like to try and confirm whether the given solution works? It would immensely help other Campaign users looking for an answer to this query.
