iOS Deferred Deep Link: Missing media_source and campaign (works on Android) #397
Description
Hi AppsFlyer team,
I'm currently testing deferred deep linking on iOS using the AppsFlyer SDK, and I've noticed that the media_source and campaign parameters are missing from the response.
This issue does not occur on Android.
Steps to Reproduce:
Generate a short link (one link) with media_source and campaign parameters on appsflyer dashboard.
Click the short link on an iOS device.
Install the app either from Xcode (IDE) or via TestFlight.
Launch the app and wait for the AppsFlyer deferred deep link callback.
Expected Result:
The deep link data should include the media_source and campaign parameters.
Actual Result:
These parameters are missing from the deep link response on iOS.
onDeepLinking method result:
DeepLink: {"af_sub4":"","click_http_referrer":"","af_sub1":"","af_sub3":"","deep_link_value":"TEST","campaign":"","match_type":"probabilistic","af_sub5":"","campaign_id":"","media_source":"","af_sub2":"","is_deferred":true}
onInstallConversionData result:
{status: success, payload: {is_first_launch: true, install_time: 2025-07-02 13:31:31.066, af_message: organic install, af_status: Organic}}
On Android, the same process correctly returns both media_source and campaign.
Notes:
I’ve tried installing from both Xcode and TestFlight after clicking the short link, but the issue persists.
On Android, clicking the same link and installing the app returns all expected data.
