AppMetrica sends an install postback for successful attribution. The install postback is sent in real time with a delay of no more than a few minutes.
AppMetrica sends an event postback when it receives the event from the app that is specified in the tracker settings. It is also necessary that this app installation was previously attributed to this tracker.
The maximum period for sending an event postback is 6 months from the time of app installation.
A postback is a GET request sent over HTTP or HTTPS (recommended) to the postback URL that is specified in the tracker settings.
Sending the postback is considered unsuccessful if:
- The HTTP response code is something other than 200-x.
- The server didn't respond within 5 seconds.
It will be re-sent every 3 minutes. If the postback was't sent successfully within 24 hours of the first attempt, no more attempts will be made.
AppMetrica uses the postback request User-Agent
