Install callbacks

Adjust servers trigger an install callback when a user opens an app for the first time after install.

The callback parameter for install callbacks is install_callback.

Important:

If you're using Branded Links or Universal Links, you must prefix the callback parameter with adj_. Use adj_install_callback for the install_callback parameter.

Recommended placeholders

Placeholder	Description	Example
`{installed_at}`	Install, that is, first app open timestamp	1404214634
`{installed_at_hour}`	Install, that is, first app open timestamp rounded to the nearest hour	1418169600
`{conversion_duration}`	Time in seconds between click and install or reattribution	72

Note:

If placeholder data is not available, it will be dropped from the callback.

Tip:

If you have not integrated with Campaign Lab, use the Encoding tool to encode your callbacks and generate the final encoded URL. If you have any questions, contact us at integration@adjust.com.
