Specific Use Case From Customer:

The goal is that every interaction with an custom domain link will bring the user into the app, if it is installed on his/her phone.

We are already able to handle links like https://www.domain.com/, bypassing the system browser and leading the user directly into the apps.

We also want to be able to handle our newsletter links, like e.g. http://links.example.com/ctt?custom_querystring_parameters. Therefore we need to prove, that we are the owner of the domain links.domain.com by placing two configuration files within that domain (one for iOS, one for Android).

We need the apple-app-site-association and assetlinks.json files to be accessible from the following URLs:

https://links.example.com/apple-app-site-association

https://links.example.com/assetlinks.json

Important: They must be accessible via https with a valid SSL certificate and need to be delivered with a Content-Type: application/json Response header without any redirection.

Once iOS and Android verify that those files are in place, we will be able to finalize our deeplinking implementation.
