InstaTG

Instagram to Telegram Channel Bot. Can access posts from any public Instagram account or an account that you follow.

Features

• Keeps track of existing sent posts to tg in an embedded db.
• Fast & Concurrent (at least as much as Telegram's rate limit allows it to be).
• You can send the latest posts at periodic intervals or send all past Instagram posts.
• Tested on Linux, but should also work across platforms (Win/Mac/Linux) and architectures (ARM/x86).

Prerequisites

• Have a spare Instagram account.
• Create a telegram bot using botfather and obtain its HTTP token.
• Create a telegram channel.
• Add your bot to your channel and make it admin.
• Get your channel chat id using https://api.telegram.org/botXXX:YYYYY/getUpdates (replace the XXX:YYYYY with your BOT HTTP API Token you just got from the Telegram BotFather)

Usage

There are two versions:

• cmd/app - Fetch the latest posts from an Instagram channel and send them to a Telegram channel.
• cmd/historical - Fetch all historical/past posts from an Instagram channel and send them to a Telegram channel.

You should probably run cmd/app as a background service while cmd/historical is a one-off.

Note: You need Go to compile it or maybe you can grab pre-compiled builds from somewhere.

Note: The directory where you place the binaries must be user writeable.

Compile using go build -o ./bin/instatg ./cmd/app

From CLI

$ ./instatg \
      -tgtoken "XXXXX:YYYYY" \
      -tgchannel "-123456789" \
      -iguser "yourusername" \
      -igpass "yourpassword" \
      -igchan "exampleaccount"
