FAQ
Which payment methods can the bot accept?
Stripe (cards, Apple Pay, Google Pay), Telegram Stars for digital goods, and crypto through a payment provider. I recommend the option that fits Telegram's payment rules for your product.
Bot or Mini App: what's the difference?
A bot works through chat messages and buttons. A Mini App is a full web interface (catalog, profile, checkout) that opens inside Telegram. Many projects start as a bot and add a Mini App later.
Where will the bot be hosted?
On your own server or cloud account (VPS, Railway, Render, Google Cloud), so you own everything. I can set it up for you; a small bot runs on a server that costs a few dollars a month.
Can the bot use AI?
Yes: GPT, Claude or Gemini for chat and content, Whisper for voice messages, plus image and video generation. I add usage limits or token billing so AI costs stay under control.
Will I get the source code?
Yes. You get the full source code, a deployment guide and admin instructions. The code is yours.
Can you update my existing bot?
Yes. Send me the code or describe the bot and I'll quote the changes. I work with Python (aiogram, python-telegram-bot), Node.js (grammY, Telegraf) and PHP or Laravel bots.
