n8n Workflow: Upload Google Drive Videos to TikTok & Instagram

Automatically turn new Google Drive videos into TikTok & Instagram posts

This n8n workflow watches a specific Google Drive folder for newly added videos, transcribes the audio with OpenAI, generates a TikTok/Instagram-ready caption, and uploads the video to both TikTok and Instagram using the upload-post.com API—optionally alerting you via Telegram

What this workflow does

• Monitors Google Drive every minute for new files created in your selected folder.
• Downloads the new video from Google Drive and saves it to the n8n file system for reuse.
• Transcribes spoken audio using OpenAI to extract the transcript text.
• Generates a social media description by prompting GPT-4o with the transcript (caption style is configurable).
• Uploads to TikTok by reading the saved video file and posting it with the generated description via the upload-post.com API.
• Uploads to Instagram using the same saved video file and the same generated description via the upload-post.com API.
• Error handling with Telegram alerts sends a notification to a Telegram chat when the workflow errors, except for a specific DNS/server-offline message.

Use cases

• Creators and teams who pre-package content in Google Drive and want it auto-posted to TikTok and Instagram.
• Automation engineers building a reliable social publishing pipeline using n8n, OpenAI, and upload-post.com.
• SaaS operators who manage content batches and need transcription-based captions without manual effort.
