iOS Deferred Deep Link Issue: Unable to Retrieve Deep Link Value

nitaking commented 3 months ago

Objective

I am currently encountering an issue with retrieving deep link values via deferred deep links on iOS. According to the AppsFlyer SDK documentation for Flutter, the SDK should be triggered by either iOS Universal Links/Android App Links for deep linking or deferred deep links.

My question revolves around which listener should be used for deferred deep links: onInstallConversionData or onDeepLinking? Based on my understanding, utilizing Unified Deep Linking (UDL) implies that onDeepLinking should be capable of handling all related events. However, in my application, the onDeepLinking listener either does not trigger, or it fails to retrieve the deep_linking_value.

I am wondering if there might be an issue with how I've implemented the SDK or if there are specific aspects I should verify.

Points of Uncertainty

On iOS, it appears that the onDeepLinking callback is not being listened to.
While onInstallConversionData does trigger for deferred deep links, it fails to capture the deep_linking_value.

Configuration and Background

onDeepLinking and onInstallConversionData are called prior to initSdk.
Standard deep links trigger correctly, and the deep_linking_value is successfully retrieved.

Any insights or guidance on resolving these issues would be greatly appreciated.

Hi @nitaking @lashket

Any update on this issue?

OnDeepLinking was called when I used the OneLink, and it's working fine on Android devices. However, OnDeepLinking is not called on iOS devices.

Hi @nitaking @lashket

OnDeepLinking was called when I used the OneLink, and it's working fine on Android devices. However, OnDeepLinking is not called on iOS devices.

I was able to get the callback from _appsflyerSdk.onDeepLinking() on iOS

Steps to trigger

press on the OneLink that you have configured from the appsflyer website
it should open web browser if your apps is still not yet published, and it should open App Store or Play Store if your app have been published
Here is the tricky part. DO NOT install the app from web browser, App Store or Play store. Instead run your app from your IDE or Xcode and remember to set showDebug to true in your AppsFlyerOptions. Let your app run until it launched.
Check your IDE log, there should be a callback triggered from _appsflyerSdk.onDeepLinking() with Status.FOUND

@justatipfromthedeadsequoiatree Thank you for description. So do you mean you can get data from onDeepLinking() on IOS, even in deferred deeplink? In my case, onDeepLinking cannot retrieve data(include any schemes too) when application is first opened with OneLink. So, I used app_links package to handle that case.

hi @SuhwanCha

Q: So do you mean you can get data from onDeepLinking() on IOS, A: Yes, i'm using Unified deep linking in this situation, onDeepLinking() got triggered when i perform the steps i mentioned above here

source from documentation

data printed on my IDE console

DeepLink: {"af_sub4":"","click_http_referrer":"","af_sub1":"","af_sub3":"","deep_link_value":"dummy_text","campaign":"","match_type":"probabilistic","af_sub5":"","campaign_id":"","media_source":"","af_sub2":"","is_deferred":true}

Q: even in deferred deeplink? A: yes, onInstallConversionData callback got triggered as well when i perform the steps i mentioned above. here As stated in the documentation, when using Deferred Deep Linking , onInstallConversionData() will get triggered .

source from documentation

data printed inside my IDE console

onInstallConversionData res: => {status: success, payload: {is_first_launch: true, install_time: 2024-04-17 15:34:09.906, af_message: organic install, af_status: Organic}}

hope it helps, regards

Thank you @justatipfromthedeadsequoiatree, I've reproduced steps on iOS, as you mentioned before.

I can get data from onInstallConversionData

onInstallConversionData: {status: success, payload: {is_first_launch: false, install_time: 2024-04-18 02:31:18.500, af_message: organic install, af_status: Organic}}

and onDeepLinking

{scheme: MY_BUNDLE_ID, request_ip_version: IP_V4, is_deferred: false, host: google, link: BUNDLE_ID://google/link/?request_ip_version=IP%5FV4&match_message=No%20pre%2Dinstall%20link%20matched%20for%20this%20device%2E, path: /link, match_message: No pre-install link matched for this device.}

But data such as deep_link_value is missing.

When UDL returns FOUND but the deep linking data is missing parameters, which are not deep_link_value and deep_link_sub1-10.

hi @SuhwanCha

i have updated my post on onDeepLinking(). I managed to get the deep_link_value.

Maybe you need to check back your configuration on appsflyer website?
