Hi Nipul! So this is going to be a bit more complex. What I would recommend doing is using a standard Facebook pixel for your website and firing a conversion event when someone texts a link. Then you can upload the list of IDFAs and/or Android IDs to Facebook as an offline conversion event so that you can track your full funnel.

Hope that helps! Feel free to reach out to me and my team on LightningAI.com if you have any other questions.
