Custom String Field vs Custom URL Field
We are capturing a personalized cart abandon URL for a cart abandon email and passing it into a field in Marketo.
My question is do I populate it into a URL field or a String field? Is one better than another for a specific reason? I know when populating a link via a token, in order to have the reporting register the token as a link, we need to leave the protocol (http:// or https://) outside of the value in the token.
Does capturing the URL in a URL field circumvent this? Do we need to leave off the protocol? Etc I'm just struggling with what the difference is between the URL field and a string and the doc isn't very clear on that.
