Yes. In the simplest case, it does not matter if your app has multiple tracking SDKs installed. You only need to integrate TROPHiT for the tracker that you are planning to use for your voucher tracking links. Simply follow the Integration Assistant instructions on your TROPHiT dashboard, after selecting the appropriate tracker.
If you are planning to generate voucher tracking links from more than one tracker, implement the TROPHiT integration instructions for each tracker.
Note: if two trackers which are Facebook MMPs are installed inside your app and you are planning to promote vouchers through Facebook, there is no guarantee which tracker would be granted the attribution by Facebook. In such a case, you should implement TROPHiT for both trackers.
