Grouptizer

Who the bot manages

Grouptizer manages access for Telegram users who joined your channel or group through the official flow — a purchase (or access-code redemption), followed by signing in with Telegram and using the invite link the app provides. That’s the only path the product is built around.

Two practical consequences worth being explicit about: connecting a chat that already has members is safe, and adding members manually doesn’t bind them to a Grouptizer purchase.

Pre-existing members

Section titled “Pre-existing members”

You can connect a private channel or group that already has people in it. They predate the integration and stay outside its scope — Grouptizer won’t audit them or remove them.

What that looks like in practice:

  • Your existing members keep their access exactly as before.
  • They aren’t visible on your Customers list (they haven’t bought through your store).
  • They don’t count against any product’s stock or customer conditions.
  • If you later want them to become tracked customers, they have to go through the official flow — see below.

The bot’s first interaction with your chat happens the first time a buyer joins via the invite link, not when you connect the integration.

The official flow

Section titled “The official flow”

For Grouptizer to manage a Telegram user as a customer, they have to complete every step:

  1. Buy on your storefront, or redeem an access code. This creates the purchase in Grouptizer.
  2. Sign in with Telegram on the app page inside their purchase. This is what links their Telegram account to that specific purchase — see Access the Telegram channel after buying.
  3. Open the invite link provided by the app page (via the QR code or the “Open in browser” link). Telegram shows a Request to join button.
  4. The bot receives the join request, matches it against the buyer’s purchases, and approves or rejects it.

Only when a buyer has completed every step will the integration manage their access automatically the way you expect.

Don’t add buyers manually

Section titled “Don’t add buyers manually”

The official flow above is the supported way to bring a buyer into your channel or group. If you add someone yourself — pasting their username, using “Add member” in Telegram, or sharing an invite link that skips approval — you’re stepping outside it, and Grouptizer doesn’t promise that everything will line up afterwards.

Two concrete reasons to stay on the supported path:

  • Your records and your channel can drift apart. The customer list in your dashboard reflects what happened in Grouptizer. Adding people directly in Telegram leaves no trace there, and you lose the audit of who’s in your chat and why.
  • Automatic access management is defined for the official flow only. Cancellations, expirations and failed renewals are designed around buyers that came in through the invite link. We don’t guarantee the same behaviour for anyone else.

If you’ve taken a payment outside Grouptizer and want to grant access, generate an access code and have the buyer redeem it. That’s the supported equivalent of “letting someone in for free”.

If someone joined manually by mistake

Section titled “If someone joined manually by mistake”

The fix is to take them out and let them come back in through the flow:

  1. Remove them from the channel or group from Telegram.
  2. Ask them to open the app page inside their purchase in Grouptizer, sign in with Telegram if they haven’t, and use the invite link from there.
  3. Once they’re back in through the official link, the integration handles their access as expected.
