Callback API

A pattern where the platform sends events (like a join) to your server.

With Callback API the platform posts events to your URL near real time — useful for joins and similar actions.

VK Callback is used to capture community joins and relate them to a prior deeplink click.

Server verification, secrets and event lists must be configured carefully or conversions stay silent.

Callbacks complement click analytics: clicks show interest; join events show media outcomes.
