The way I would implement it is as a “proxy” on my own network, eg trackingservice.myapp.com, that is just a web server listening and forwarding requests (technically a MITM). Override the request method of the client SDK to hit my endpoint instead of the tracking service. Obviously you then pay the bandwidth, but it’s likely negligible compared to your app traffic. As a bonus you’ll probably circumvent adblockers. If you want to avoid traffic forwarding, but keep flexibility over the endpoint, you can override the init of the sdk to first query your server for which endpoint to use. That way if the third party service goes down, you just need to change the config on the server.
