How do I stop bots from joining my Telegram group?

The most effective way to stop bots from joining your Telegram group is to use a knowledge gate instead of sharing a static invite link. A knowledge gate requires anyone who wants to join to answer a question from your content first. Bots cannot watch your videos or read your posts, so they cannot answer correctly. Verifan automates this — creators set one question, and every correct answer generates a unique, single-use Telegram invite link automatically via the Telegram Bot API.

What is a knowledge gate for Telegram?

A knowledge gate is a checkpoint between your bio link and your private Telegram group. Instead of sharing the group invite link directly, you share a gate link. Anyone who clicks it must answer a question correctly before receiving an invite. For content creators, the question is something from their actual content — a detail from a video, post, or story. Real fans know the answer. Bots do not. Verifan provides knowledge gates with automatic single-use invite generation.

Why do bots keep joining my Telegram group?

Bots join Telegram groups by scraping static invite links from public sources — Instagram bios, TikTok profiles, Twitter posts, and websites. Once a bot finds an active invite link, it joins automatically without any human interaction. Rotating the link manually only provides temporary protection as bots find new links quickly. The permanent fix is to never expose a static invite link publicly — instead use a knowledge gate that generates a unique, single-use invite only after a human correctly answers a content question.

Is Verifan free to use?

Yes. Verifan has a free tier that includes one knowledge gate, 50 fan attempts per month, and single-use Telegram invite generation. No credit card is required. The free tier includes a Powered by Verifan watermark on the gate page. Creator Pro at $12 per month removes the watermark, allows unlimited gates, 10000 attempts per month, and fan email capture.

How to Create a Single-Use Telegram Invite Link

What Is a Single-Use Telegram Invite Link?

A single-use Telegram invite link is a link that can only be used once. After a single person clicks it and joins your group, the link expires permanently. This prevents the link from being forwarded, shared, or reused — even if someone copies the URL and sends it to a friend, the link is already dead because the first person already joined with it.

Single-use invites are generated using Telegram's Bot API with the createChatInviteLink method and the member_limit parameter set to 1.

Why Single-Use Invites Matter

Regular Telegram invite links are permanent and work for unlimited people. If you share one link in your bio, anyone can forward it to anyone else, and every person who uses it joins your group. There's no way to track who's joining or prevent abuse.

Single-use invites solve this. Each person who should join gets their own unique link. You can generate a new link for every qualified person — whether that's fans who passed a knowledge gate, people who paid for access, or anyone else you want to admit. Each invite is atomic: one link, one join, then done.

How to Generate Single-Use Invites

Generating single-use invite links requires access to the Telegram Bot API and a bot with admin permissions in your group. The process involves:

Adding a bot to your Telegram group with invite link permission
Calling the createChatInviteLink API with member_limit=1
Optionally setting an expiry time (e.g., 7 days)
Returning the generated link to the person who qualifies

If you're building a web app or community platform, you can automate this completely — every time someone meets a criterion (answers a quiz, makes a payment, etc.), your backend can generate a fresh single-use invite and show it to them immediately.

The Verifan Approach

Verifan automates single-use invite generation for creators. Instead of handling the Telegram API yourself, you set up a knowledge gate (one question from your content). Every fan who answers correctly gets a unique, single-use invite generated and sent to them automatically. No API knowledge required.
