We use Universal campaign in Google Adwords and usual Facebook campaign for apps. We don't pass branch links for these campaigns. In branch analytics I see installs and conversion events for these campaigns. But also I would expect parameters 'channel' and 'campaign' within
Branch.getInstance().initSession(launchOptions: launchOptions) { (parameters, error) in
// Expect 'channel' and 'campaign' parameters here
}
For the search campaign in Google Adwords we use the branch link and receive the campaign.
