Appsflyer. The conversion data doesn't come to TWA.

[LupusX5]

I have created an app using Bubblewrap, with the enabled feature of Appsflyer – it's needed to receive the google play referrer information.

But I have kind of unexpected behaviour:

When I launch the app the following happens: on open the app opens a url with the appsflyer_id query parameter. I.e. the following url is being opened: https://angus.surge.sh/?appsflyer_id=xxxxxxxx. However, it doesn't receive any cookies in response afterwards as expected according to Appsflyer documentation.

Screenshot №1 + source URL: https://support.appsflyer.com/hc/en-us/articles/360002330178-Using-AppsFlyer-with-TWA#append-appsflyer-id-and-customer-user-id-to-url:

Screenshot №2: expected cookies on the client side (the same source as Screenshot №1):

And this is my source code: https://github.com/LupusX5/twa-demo

Could you please help solve this issue?

Partly resolved: the issues with getting the converision data and sharing it with the server is fixed. However I'm still searching for better option to pass the conversion data to the url. Within a few days may come up with a solution and will share the code.

I guess the best place to document the AppsFlyer flow is in the AppsFlyer docs themselves. Nevertheless, any updates here?

Programming language used in this comment: Kotlin.

Hello! Yep. I have managed to use it with Chrome Custom Tabs, but not still figured out how to do that with the TWA. The issue is that for Chrome Custom Tabs I see the way of using it, and in TWA there's one thing that doesn't let me to get normally the idea.

So this is the problematic place for me:

class LauncherActivity : LauncherActivity() {
    override fun getLaunchingUrl(): Uri {
        val uri = super.getLaunchingUrl()
        val appsFlyerId = AppsFlyerLib.getInstance().getAppsFlyerUID(this)
        uri
            .buildUpon()
            .appendQueryParameter("appsflyer_id", appsFlyerId)
            .build()
        return uri
    }
...
}

So what's the issue here. The issue is that I can't launch this code or any of its parts inside an AppsFlyer caller function.

Let me show you what I'm talking about with a working example. Here in this case I can do what I need, but I need it for TWA as well :) I guess many people would love to have it as it makes marketing more efficient.

Hello @LupusX5. Were you able to resolve this issue and get conversation data on the TWA?
