I am wondering if it's possible to track referrals when my website is opened from mobile app? Is there any related information provided in request headers?
Particularly interested to know if it's opened from Facebook mobile app or Instagram mobile app.
Look for the utm_source and utm_medium request parameters on your website. If they don't exist, then the best you're going to get is the user-agent of the device. Alternatively, if you're keen to always use bit.ly type shortened links, you could use a different one everywhere you post the link.
