Downloading Channel Data

Introduction

This vignette demonstrates how to download channel data with telegramR using the high‑level helpers.

Offline Demo (No Telegram Connection)

To keep the vignette reproducible, the outputs below come from a bundled sample dataset. The commands shown are the real calls you would use against Telegram.

Setup and Authentication

library(telegramR)

# Replace these with your own API ID and Hash
api_id <- 123456
api_hash <- "0123456789abcdef0123456789abcdef"

client <- TelegramClient$new("my_session", api_id, api_hash)
client$start()

Download Messages

# Download the most recent 200 messages from a channel
msgs <- download_channel_messages(
  client,
  "telegram",
  limit = 200
)

Example Output (Bundled Sample)

msgs_by_id <- download_channel_messages(client, 1234567890, limit = 100)
