How can I track user events across different platforms (like web and server) and send notifications to Telegram based on these events?

You can track user events from any platform and then message users in Telegram from a Customer Journey. Telegram is now a native Pushwoosh channel, so you no longer need a webhook to the Telegram Bot API.

1. Track user events

   • Web: the Web SDK automatically posts the built-in PW_SiteOpened event on every page open, with url, title and device_type attributes. See Default events. Note that the Web SDK's event handlers (subscribe, unsubscribe, permission-granted, and so on) only report subscription and permission changes — they are not used for tracking user actions.
   • Custom events (website, server-side, bot): create the event in Audience > Events first, then send it with the /postEvent API method or the SDK's postEvent. See Custom events.

2. Send the Telegram message

   • Add the Telegram element to your journey canvas and enter the body in Message text. Keep it text-only and within 4096 characters. Messages reach users who have started your bot and entered the journey.
   • You can personalize the text with tags and Liquid placeholders, and attach voucher codes by enabling Use vouchers and adding {{voucher}} to the text.
   • If Telegram reports bot blocked or chat not found, the user is marked unreachable for Telegram and appears in the Skipped rows of the journey statistics.
   • See Journey elements — Telegram and Send Telegram messages in Customer Journey.

If you need to reach a system that has no native channel, the Webhook element is still the right tool; see the webhook samples for a payload example.
