How to Build a Telegram Bot That Sells Virtual Numbers
If you want to telegram bot sell virtual numbers automatically, you need three things: a bot token, a payment flow and an SMS activation API. This tutorial walks through the full build in plain language, from creating the bot to delivering the OTP code to the buyer.
Direct answer: Create a bot with BotFather, code it in Python or Node.js, connect it to the OtpGet SMS activation API, add a balance or payment step, then let the bot order a number, show it to the user, poll for the SMS and send the code back in chat.
Why a Telegram Bot Is a Good Sales Channel
Telegram bots are fast to build, work on every platform and require no app store approval. Users already trust the interface, and you can push order updates instantly. For a virtual number store, the chat format maps perfectly to a simple flow: choose country, choose service, pay, receive number, receive code.
Step 1: Create Your Bot and Get the Token
- Open BotFather in Telegram and send /newbot.
- Pick a name and a username ending in "bot".
- Copy the token and store it as an environment variable.
- Never commit the token to a public repository.
Step 2: Plan the User Flow
- Start: welcome message with a short menu.
- Choose country: inline buttons for the countries you support.
- Choose service: inline buttons for popular apps.
- Pay: deduct from the user's bot balance or accept a top-up.
- Receive number: the bot sends the number and a countdown.
- Receive code: the bot polls and sends the OTP when it arrives.
Step 3: Connect the SMS Activation API
The bot should never hardcode supplier logic. Instead, call the OtpGet API endpoints for ordering, checking status and cancelling. Read the API documentation first so you know the exact parameters.
A typical order call sends the country, the service and your API key, and returns an order ID plus the phone number. Save the order ID in your database alongside the Telegram user ID so you can match the code to the right buyer.
Step 4: Poll for the OTP Code
After the number is delivered, the bot asks the API for the SMS status every few seconds. When the code arrives, extract it and send it to the user. If the order times out, cancel it and refund the bot balance. Our guide on how to poll for OTP codes in Python without wasting requests explains the timing rules in detail.
Step 5: Handle Errors Gracefully
Customers lose trust when a bot freezes. Map each sms activation api error codes response to a friendly message:
| Code | User message |
|---|---|
| NO_NUMBERS | "That country is out of stock. Try another country." |
| NO_BALANCE | "Our stock system is busy. Please try again shortly." |
For NO_BALANCE you should also alert yourself, because it means your reseller balance is empty.
Step 6: Add Balance Top-Ups
Users need a way to pay. Options include manual payment approval, crypto deposits such as USDT, or local methods like JazzCash. If you go local, read our guide on adding balance with JazzCash and USDT for virtual numbers so the deposit flow is clean.
Step 7: Secure and Scale
- Rate-limit commands to prevent abuse.
- Log every order and every API response.
- Never show the raw API key in chat or logs.
- Monitor failed orders daily and fix patterns.
