The link value is replace by dummy value but idea is the link generated from iOS should be the same as Android.

To Reproduce Steps to reproduce the behavior:

On iOS

1. Init AppsFlyer SDK

 AppsFlyerOptions appsFlyerOptions = AppsFlyerOptions(
        afDevKey: devKey,
        appId: appId,
        showDebug: true,
        timeToWaitForATTUserAuthorization: 60,
        // for iOS 14.5
        appInviteOneLink: oneLinkID,
        // Optional field
        disableAdvertisingIdentifier: false,
        // Optional field
        disableCollectASA: false);

await _appsFlyerSdk?.initSdk(
      registerConversionDataCallback: true,
      registerOnAppOpenAttributionCallback: true,
      registerOnDeepLinkingCallback: true,
);

2. Create app invite link.

 AppsFlyerInviteLinkParams inviteLinkParams = AppsFlyerInviteLinkParams(
        channel: "app_invite",
        referrerName: "",
        baseDeepLink: deeplinkValue,
        brandDomain: "",
        customerID: uid ?? "",
        referreImageUrl: "",
        campaign: "app_invite",
        customParams: {
          "af_og_image": imageUrl,
          "af_og_title": title,
          "af_og_description": description.characters.take(80).toString(),
          "af_dp": deeplinkValue,
          "deep_link_value": deeplinkValue,
        });

    _appsFlyerSdk?.generateInviteLink(inviteLinkParams, (result) {
      var link = result['payload']['userInviteURL'];
      onLinkCreated(link);
    }, (error) {
      debugPrint(error);
   });

3. Check result

result['payload']['userInviteURL'];

4. See error The userInviteURL different from on Android. The url include all detail in the queryParam

Expected behavior The userInviteURL should be the same as Android in this format https://dev-myapp.onelink.me/ABCD/h31b26w1

1. Device: iPhone 11, OS: iOS 15.1
2. Device: iPad Pro (11-inch) (3rd gen), OS: iOS 16.3.1

@BenBoonya Did you fix it?

[raulmabe-labhouse]

For anyone wondering, just remove the brandDomain: "". Leave it null

[esentis]

Is this iOS specific because I can see some Android users of mine with the same behaviour.

[vanvixi]

I encountered a similar issue as yours, and after several days of investigation, I identified the problem lying within the brandDomain parameter in AppsFlyerInviteLinkParams.

"If brandDomain.isEmpty == true or you haven't registered brandDomain or brandDomain hasn't been configured successfully, it will result in an error preventing the creation of a shortened link." (brandDomain must be accurately configured here).

To resolve this issue, you simply need to remove the brandDomain or set brandDomain: null.

Befor:

      final AppsFlyerInviteLinkParams inviteLinkParams = AppsFlyerInviteLinkParams(
        brandDomain: _brandDomain,
        customerID: customerID,
        customParams: customParams,
        ...
      );

Resolved:

      final AppsFlyerInviteLinkParams inviteLinkParams = AppsFlyerInviteLinkParams(
        customerID: customerID,
        customParams: customParams,
        ...
      );
