The choice between SUB_ID and ACTION_DATA methods is defined by the requirements for the Postbacks:
This is based on the fact that the two methods process different types of Conversion Keys.
While using the SUB_ID method, the resulting Conversion Key contains the information about the Placement ID, Banner ID, Country, OS, and Browser, but most importantly - the Action Key.
On the other hand, the Conversion Key in the ACTION_DATA method only contains Placement ID, Banner ID, Country, OS, and Browser. The Action Key is processed separately, which makes it usable for multiple different Actions.
