1. The start

   An Instagram page that ran itself

   I wanted to test an idea: an Instagram page about cute animals, fed by videos that already existed on TikTok, with every creator properly credited. The idea was simple. The work behind each post wasn't: download the video, re-encode it, retype the caption, copy the hashtags, credit the author. Every single time.

2. The goal

   One link in, one post out

   Turn all of that into a single gesture. Share a TikTok with a Telegram bot and get back a finished Instagram post, with the original description, the hashtags and a credit to the creator. Telegram would be the control panel: nothing to build for the interface, it works on every device, and progress updates are just messages.

3. The adventure

   Four services, one pipeline

   The bot listened for TikTok links, downloaded the video with its metadata, converted it with FFmpeg and published it on Instagram, reporting each step in the chat. For several weeks it did exactly what I wanted: I shared a video, watched the status messages roll in, and opened a finished post with its caption, hashtags and credit intact.

4. The difficulties

   Building on ground that moves

   Every external piece was unofficial. There's no public API for downloading TikToks or for posting as a regular Instagram account, so endpoints and authentication could change overnight. Both platforms also watch for automated traffic, which meant rate limiting, rotating user agents and spacing requests out. And TikTok's videos had to become something Instagram accepts without a visible loss in quality.

5. The end

   A proof of concept that made its point

   After several weeks, TikTok and Instagram changed the unofficial endpoints the bot relied on, and it stopped working. I kept it as a proof of concept instead of chasing a moving target. It showed that automated cross-platform conversion with proper attribution is feasible, and it taught me how much a system built on unofficial APIs depends on things you don't control. For anything meant to last, that dependency is the first thing to design around.

• Telegram as the control panel

  Send the bot a TikTok link from any device. It validates the link and reports every step back as a chat message.

• Video processing

  Downloads the video and re-encodes it into a format and aspect ratio Instagram accepts.

• Instagram publishing

  Posts the result automatically, with the caption formatted for Instagram.

• Metadata kept intact

  The original description and hashtags travel with the video, and every post credits the creator who made it.

• Hands-off workflow

  From the link to the published post with no manual step in between.

• Several APIs, one flow

  TikTok and Instagram's unofficial endpoints, each wrapped in its own small adapter.

The bot in action

Here's the whole workflow, from sharing a TikTok to opening the finished Instagram post.

The pipeline

1. Link detection

   The bot watches its chat for TikTok links and validates them, whatever the URL format.

2. Extraction

   It downloads the video and reads the caption, hashtags and author through TikTok's unofficial endpoints.

3. Re-encoding

   FFmpeg converts the video for Instagram, keeping the quality and the aspect ratio.

4. Publishing

   It posts to Instagram with the original metadata and a credit, then replies with the post's link.

Under the hood

• Telegram bot framework

  python-telegram-bot

  Handles the conversation: detecting links, answering, and sending status updates throughout the conversion.

• TikTok integration

  Unofficial endpoints

  Provide the video, its metadata and the creator's details, across TikTok's different URL formats and video types.

• Video processing

  FFmpeg

  Converts and optimizes each video so Instagram accepts it, keeping its quality and aspect ratio.

• Instagram integration

  Unofficial endpoints

  Handle the upload, the caption formatting and the hashtags, within the platform's guidelines.

Challenges

Skills I gained

• Bot development in Python

  python-telegram-bot

  A Telegram bot that handles user interactions, detects links and reports progress in real time.

• API integration

  TikTok and Instagram

  Authentication, rate limits and data extraction on unofficial APIs, plus fallbacks for when they change.

• Video processing

  FFmpeg

  A conversion pipeline that turns TikTok videos into Instagram-ready files without hurting quality.

• Automation workflows

  Cross-platform content

  An end-to-end flow for converting, crediting and publishing content with no manual steps.
