# Telegram channel history backfill — full archive, no API key

**Use case:** 

Export a Telegram channel's FULL message history — not just recent posts. The public preview paginates all the way back (verified: 11 years of one channel in a single run), with views, reactions and media URLs, no API key and no login. Billing is per started block of 1,000 messages, so deep backfills cost the same per message as small pulls. For OSINT and crypto research.

## Input

```json
{
  "channels": [
    "durov"
  ],
  "mode": "web_preview",
  "maxMessagesPerChannel": 5000,
  "deltaMode": false,
  "deltaStateKey": "default",
  "extractMedia": true,
  "extractReactions": true,
  "extractMemberData": false
}
```

## Output

```json
{
  "channel_name": {
    "label": "Channel",
    "format": "string"
  },
  "date": {
    "label": "Date",

  },
  "text": {

  },
  "media_type": {
    "label": "Media",
    "format": "string"
  },
  "message_url": {
    "label": "Link",

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
