Overview

Telegram MTProto is the full-featured Telegram API that lets you build custom Telegram clients and read/write data for real user accounts, not just bots. It uses Telegram's own encrypted MTProto protocol, which requires OAuth authentication and a dedicated client library. This API is best for advanced developers building full Telegram clients or user-level automation.

Beginner Tip

Start with the simpler Telegram Bot API for most projects; use MTProto only when you need full user-account access. You will need an app_id and app_hash from my.telegram.org to get started.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Use case: Integrate read and write telegram data data into web and mobile applications

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

JSON Response · Illustrative

{
  "status": "success",
  "data": {
    "result": "Data from Telegram MTProto",
    "description": "Read and write Telegram data",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

_ The TL (Type Language) constructor name identifying the response type.

id Unique identifier for the object, such as a message or user.

flags Bitmask encoding optional field presence; check docs for each bit meaning.

date Unix timestamp of when the object was created or sent.

message Text content of a message object.

Implementation Example

Request skeleton. The URL below is this API's documentation page, not a live endpoint — swap in the path you need from the provider's docs before running it.

Request

const url = "https://core.telegram.org/api";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "Authorization": "Bearer YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

AUTH_KEY_UNREGISTERED The authorization key has not been registered or has expired.

✓ Re-run the authentication flow to generate a fresh auth key for your session.

PHONE_NUMBER_INVALID The phone number provided during login is in the wrong format.

✓ Supply the phone number in full international format, e.g., +12025550100.

FLOOD_WAIT_X Too many requests were sent in a short period, triggering a rate limit.

✓ Wait the number of seconds indicated by X in the error before retrying your request.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
