Telegram Bot Guides & Tutorials

Step-by-step guides to building, hosting and monetizing Telegram bots — selling digital products, paid channels, crypto payments and more.

• Free AI Chatbot for Telegram With OpenRouter (No Card) — Make a free AI chatbot in Telegram: get a free OpenRouter key, pick the free model, fix the privacy-setting error and know the daily limit before sharing.
• Add Your Bot as Admin of a Private Telegram Channel — Connect a private channel or group to your paid-access bot: make the bot an admin with the right rights, fix 'not found', and close old invite links.
• Star Subscriptions for a Paid Channel: Native Link or Bot? — Telegram's own Star subscription link vs a subscription bot for a paid channel: plans, trials, promo codes, renewals and what you receive, side by side.
• Telegram Stars Payment Failed? Causes and Fixes — Why a Telegram Stars payment fails or a bot can't take Stars, and how buyers and sellers fix it: store and card issues, limits, paused shops, refunds.
• How to Accept Telegram Stars in Your Bot (No Code) — Turn on Telegram Stars in a TeleCrow shop or paid-channel bot in three taps, test it with 1 Star, and learn your seller duties: /paysupport and refunds.
• Telegram Stars to USD: What 100 to 10,000 Stars Are Worth — What Telegram Stars cost buyers and what sellers get: a 100 to 10,000 Stars table, how to check rupee prices, the 21-day hold and a $10 example.
• Are Telegram Bots Safe? What a Bot Can and Can't See — What a Telegram bot can and can't see about you, the real risks such as fake 'earn money' and 'verify' bots, and how to check a bot before you trust it.
• How to Sell a Video Course on Telegram (Step by Step) — Sell a course on Telegram: video lessons in a private channel, workbooks as files, a one-off or monthly price, automatic access and removal, a checklist.
• Telegram File Library Bot: Share Files With Your Members — Set up a free file library in Telegram: upload PDFs, templates or zip files, let members browse and search them, and ask people to join your channel first.
• Telegram Bot Not Responding? 12 Causes and Fixes — Your Telegram bot stopped replying? Check these causes in order: stopped bot, changed token, token used twice, group privacy, daily limit, AI key and more.
• Is This Telegram Seller Legit? 9 Checks Before You Pay — How to tell a Telegram seller is real before you pay, the red flags of a scam, and what honest sellers show: receipts, refunds, support, in-app payment.
• Is Creating a Telegram Bot Free? Costs and Limits — Making a Telegram bot is free; running and selling with it can cost money. What's free, what TeleCrow's Free plan includes, its daily limit, when to pay.
• The Telegram Bot API Methods That Actually Matter, Grouped by Job — A working reference for the Telegram Bot API methods behind paid channels, ticketing, moderation and delivery, with the limits and footguns that bite.
• Telegram Mini App vs Bot: What to Build for Which Job — A bot is a conversation; a Mini App is a web app inside Telegram. The decision is about interface shape, not capability — and most products need one, not both.
• Telegram Bot API Errors: Which Ones to Retry and Which to Never Retry — Only 429 and 5xx are worth retrying, and on a flood-control 429 Telegram usually tells you how long to wait. Everything else needs handling, not persistence.
• Debugging Telegram Webhook Failures: Start With getWebhookInfo — Telegram will tell you why it can't reach your bot, in one API call. A diagnostic order for a webhook that has stopped delivering updates.
• Telegram Bot API Changes, May to August 2026: Four Releases — Bot API 10.0-10.3, May to August 2026: Guest Mode, Rich Messages, ephemeral messages, and two parameters replaced across thirteen send methods. What to check.
• Scaling Past Telegram's Rate Limits: Queues, Backoff and What Not to Try — You cannot raise Telegram's limits with better code — only with Paid Broadcasts, which most bots can't use. The engineering that makes the ceiling survivable.
• Why Free Telegram Bot Hosting Fails, and Exactly When — Free hosting doesn't fail because of CPU. It fails when the instance sleeps, webhook deliveries fail, and Telegram drops queued updates after 24 hours.
• Telegram Bot Monitoring: Why Your Health Checks Miss Outages — Almost every Telegram bot outage looks identical from inside: a healthy process receiving nothing. Health checks that measure the process cannot see it.
• What Telegram Bot Hosting Actually Costs, by Message Volume — Bots are cheap to run and expensive to run badly. What consumes resources at 10k, 100k and 1M messages a month, and why the database costs more than the bot.
• The Certificate Requirement That Silently Kills Telegram Bots — Telegram webhooks require valid HTTPS, and an expired certificate stops update delivery while your process, port and memory checks all still report healthy.
• Telegram Webhooks vs Polling: The Decision, With Failure Modes — Webhooks need HTTPS on one of four ports and fail silently when your certificate expires. Polling needs none of that and costs you latency. How to choose.
• Re-engaging Dormant Telegram Subscribers Without Getting Blocked — There's no open rate on Telegram, so dormancy has to be inferred — and a re-engagement campaign is the one most likely to get your bot blocked.
