AlterCPA TOP
AlterCPA TOP is a conversion-tracking platform for Telegram. It watches who joins your channel or group through your bot and reports every step to your tracker as clean CPA postbacks — so a Telegram subscription shows up in your tracker just like any other lead.
How it works
You drive paid traffic to a deep link — AlterCPA TOP handles the rest:
- Deep-link click. A subscriber opens
t.me/yourbot?start=CAMPAIGNCODE-{click}and presses Start in your bot. - Start & lead. The bot shows the welcome message with a CPA button,
AlterCPA TOP creates a Lead and fires a
waitpostback to your tracker. - Join. The subscriber joins your channel or group — an
approvepostback fires. If the chat requires join approval, the lead passes throughholdfirst. - Unsubscribe. The subscriber leaves on their own (
cancel) or is removed (trash). The postback fires only if it happened within the unsubscribe window.
The {click} in the deep link is your tracker’s click id — it travels with
the subscriber so every postback can be matched back to the right click record
in your tracker. No manual matching, no spreadsheets.
All five events and the conditions for firing them are in How tracking works.
Key concepts
| Term | Meaning |
|---|---|
| Bot | A Telegram bot you own, connected to AlterCPA TOP by its API token. The bot greets subscribers and watches your chats. |
| Campaign | A tracked channel/group + welcome creative + postback configuration. Each campaign produces a unique deep link. |
| Lead | One conversion record — one subscriber inside one campaign. Moves through wait → approve → cancel/trash. |
| Click | The click id from your tracker, carried in the deep link as {click}. |
| Postback | An HTTP call we fire to your tracker when a lead changes status. |
More than tracking
Conversion tracking is the core of AlterCPA TOP, but the same bot can carry the subscriber further:
- Welcome screens — multi-step button flows instead of a single message.
- Broadcasts — automatic per-status follow-ups and one-off blasts to your leads.
- Audience protection — auto-kick bots and spammers from the CAS list, plus chat cleanup.
- Operator CRM — a live chat where real operators answer subscribers right inside the bot.
