What is Telegram SMS Verification?
Telegram SMS verification is a security mechanism that uses text messages to verify user identity when creating accounts, accessing sensitive features, or performing administrative actions. This verification process ensures that only users with access to the registered phone number can complete critical operations.
Our API service provides the infrastructure needed to implement this verification system, offering virtual phone numbers and reliable SMS delivery for Telegram applications. This is particularly useful for bot developers, channel administrators, and businesses using Telegram for communication.
Benefits of SMS Verification for Telegram
Account Security
Prevents unauthorized access and protects user accounts from potential security breaches.
Bot Protection
Secures Telegram bots from malicious attacks and ensures only authorized users can access admin features.
Channel Management
Provides secure access control for channel administrators and moderators.
Business Verification
Establishes trust and credibility for businesses using Telegram for customer communication.
Setting Up Telegram Bot API
Step 1: Create a Telegram Bot
Start by creating a new bot through BotFather on Telegram and obtain your bot token.
/newbot
Bot Name: YourBotName
Username: your_bot_username
Bot Token: 1234567890:ABCdefGHIjklMNOpqrsTUVwxyzStep 2: Configure Webhook
Set up a webhook to receive updates from Telegram when users interact with your bot.
https://api.telegram.org/bot{TOKEN}/setWebhook
?url=https://yourdomain.com/webhookStep 3: Integrate VerifyPulse API
Connect your bot to our SMS verification service for secure user authentication.
const verifyPulseAPI = new VerifyPulseAPI('YOUR_API_KEY');
const virtualNumber = await verifyPulseAPI.requestNumber('telegram', 'US');SMS Verification Implementation
User Registration Flow
User Requests Verification
User sends a command to your bot requesting SMS verification.
Generate Verification Code
Bot generates a unique verification code and requests a virtual number.
Send SMS
Verification code is sent via SMS to the user's phone number.
Verify Code
User enters the code, and bot validates it for account activation.
Code Example: Basic Verification Handler
bot.command('verify', async (ctx) => {
const userId = ctx.from.id;
const verificationCode = generateCode();
const virtualNumber = await requestVirtualNumber();
await sendSMS(virtualNumber, `Your verification code: ${verificationCode}`);
await ctx.reply('Please enter the verification code sent to your phone.');
ctx.session.verificationCode = verificationCode;
ctx.session.awaitingVerification = true;
