Get Started

Meet Maya, a developer building a two-factor authentication system for a financial platform. Her users are already on Telegram — the app they check dozens of times a day. Instead of routing verification codes through SMS, she decides to send them directly into Telegram conversations. The code arrives instantly, in the app the user already has open, with no extra steps required.

Her verification rates jump. Support tickets drop. Users love it.

This is the power of Telegram OTP Communication.

Overview​

Telegram OTP delivers one-time passwords and verification codes directly through the Telegram messaging platform via the Telegram Gateway API. Unlike SMS, Telegram messages are delivered over the internet — making them faster, cheaper, and verifiable in real time.

This service handles the entire OTP lifecycle: sending the code, checking whether the target number can receive it, tracking delivery and read status, verifying the code the user entered, and revoking codes that are no longer needed.

A Smarter Way to Verify​

For teams like Maya's, Telegram OTP removes friction at every step. There is no need to maintain separate SMS infrastructure, no carrier routing complexity, and no delay waiting for network delivery.

The code goes out through Telegram, the user reads it in their existing conversation, and your system knows the moment it is delivered, read, and verified — in real time.

How It Works​

Telegram OTP verification sends a structured message to the recipient's Telegram account via the Telegram Gateway API. The system tracks the full message lifecycle through webhook callbacks from Telegram, and exposes check endpoints so your application can confirm delivery and code validity at any point.

  • Send the Code: Your platform calls the OTP endpoint with the recipient's phone number and optional code parameters. The system dispatches the message through the Telegram Gateway.

  • Check Delivery: Before sending, use the check-send-ability endpoint to confirm that Telegram can reach the number. After sending, check verification status to see whether the user has entered the correct code.

  • Track Everything: Telegram sends real-time delivery reports back through a webhook. Every status change — sent, delivered, read, expired — is recorded against the message's delivery record.

  • Revoke When Needed: If a code expires or a new one needs to be issued, the revoke endpoint cancels the outstanding verification cleanly.

Key Advantages​

  • Real-Time Verification: Know exactly when a code was delivered, read, and whether the user entered it correctly.
  • Cost Efficient: Internet-based delivery avoids SMS termination costs, particularly valuable at scale.
  • High Open Rates: Telegram messages are read faster than SMS, with open rates consistently above 90%.
  • Full Lifecycle Control: Send, check, verify, and revoke — your application stays in control at every step.
  • Secure Webhooks: Telegram Gateway callbacks are verified with HMAC-SHA256 signatures, preventing spoofed delivery reports.

Imagine the Possibilities​

  • User Authentication: Secure login flows with codes delivered directly into Telegram.
  • Transaction Confirmation: Verify high-value actions with a real-time code sent to the user's Telegram.
  • Account Recovery: Let users regain access through a trusted channel they already use.
  • Onboarding Verification: Confirm new users during registration with instant, verifiable delivery.

Your Journey Begins Here​

Maya's users complete verification faster, with fewer drop-offs and a much better experience. The authentication step that used to cause friction is now a seamless moment in their Telegram inbox.

With Telegram OTP, you are not just sending a code — you are delivering confidence, through the channel your users already trust.
