Automated Instagram reels workflow
This workflow automates the process of creating and posting Instagram Reels, combining Google Drive, AI, Airtable, and the Facebook Graph API. It supports two content creation paths:
- Scheduled Random Video Selection & Posting
Selects a random video from a Google Drive folder named "Random video mover" based on a schedule.
Moves the video to a processing folder for posting.
- Manual Upload Trigger & Posting
Watches a specific Google Drive folder ("n8n reels automation on instagram").
Triggers the workflow when a new video is uploaded.
Core Process (applies to both paths)
Download Video from Google Drive.
AI Caption Generation with Google Gemini, using the file name as context. The AI creates concise captions with hashtags and a call-to-action.
Airtable Logging to store video name, caption, and URL.
Instagram Reels Posting via the Facebook Graph API.
Recent Change In early 2025, Meta tightened its requirements for video_url and image_url parameters. URLs must now be direct, public links to the raw media file with no redirects or authentication. Google Drive links no longer work.
Our Fix
Store the binary file locally on the n8n server at /tmp/video.mp4.
Serve the file through a public n8n webhook with the correct Content-Type.
Use the webhook URL in the Facebook Graph API request.
Upload succeeds without the “Media download has failed” error.
Cleanup
Deletes the temporary file after posting.
Benefits
Saves time with full automation.
Improves engagement through AI-generated captions.
Keeps content organized in Airtable.
Works with Meta’s updated API requirements by hosting files directly from the n8n server.
# Automated Instagram Reels Workflow
This n8n workflow automates the creation and publishing of Instagram Reels by leveraging content from Google Drive and Airtable, with AI-powered content generation and scheduling capabilities. It streamlines the process of transforming raw content into engaging short-form videos for Instagram.
## What it does
This workflow performs the following key steps:
1. **Triggers on Schedule**: The workflow starts on a predefined schedule, ensuring regular content generation and posting.
2. **Fetches Content from Google Drive**: It retrieves video files from a specified Google Drive folder, which serve as the base for the Reels.
3. **Fetches Metadata from Airtable**: It queries an Airtable base to get additional metadata, such as captions, hashtags, or other relevant information for the Instagram posts.
4. **Generates AI-Powered Content**: An AI Agent (likely powered by Google Gemini Chat Model) processes the retrieved information to generate engaging captions, relevant hashtags, or even script ideas for the Reels.
5. **Prepares Content for Instagram**: It uses a Code node to process and format the data, potentially combining video file information with the AI-generated text.
6. **Uploads to Instagram**: The workflow then uses the Facebook Graph API node to upload the video as an Instagram Reel, including the generated caption and hashtags.
7. **Schedules Future Posts (Implicit)**: Although not explicitly shown with a "schedule" node, the `Wait` node suggests a delay, which could be used to space out posts or allow for manual review before the final Instagram post. The `Webhook` and `Respond to Webhook` nodes indicate it might also support external triggers or provide feedback.
8. **Manages Files (Implicit)**: The `Read/Write Files from Disk` node suggests local file operations, possibly for temporary storage or processing of video files before upload.
## Prerequisites/Requirements
To use this workflow, you will need:
* **n8n Instance**: A running instance of n8n.
* **Google Drive Account**: Configured with credentials in n8n to access your video content.
* **Airtable Account**: Configured with credentials in n8n to access your content metadata base.
* **Facebook Graph API Credentials**: An Instagram Business Account connected to a Facebook Page, and a Facebook Graph API access token configured in n8n.
* **Google Gemini Chat Model Credentials**: API key or access for Google Gemini (or a compatible AI service) for the AI Agent node.
## Setup/Usage
1. **Import the workflow**: Download the JSON provided and import it into your n8n instance.
2. **Configure Credentials**:
* Set up your **Google Drive** credentials.
* Set up your **Airtable** credentials.
* Set up your **Facebook Graph API** credentials, ensuring it has permissions to post to Instagram.
* Set up your **Google Gemini Chat Model** credentials.
3. **Customize Nodes**:
* **Google Drive Trigger / Google Drive**: Specify the folder where your video files are located.
* **Airtable**: Configure the base and table from which to fetch content metadata.
* **AI Agent**: Adjust the prompt and parameters for the Google Gemini Chat Model to generate the desired captions and hashtags.
* **Code**: Modify the JavaScript code to match your specific data structure and content processing needs.
* **Facebook Graph API**: Ensure the correct Instagram account is selected and map the video file and caption data from previous nodes.
* **Schedule Trigger**: Define your desired schedule for the workflow to run (e.g., daily, weekly).
* **Wait**: Adjust the delay if you need to space out posts or allow for review.
4. **Activate the Workflow**: Once configured, activate the workflow to start automating your Instagram Reels.
This workflow provides a robust foundation for automating your Instagram Reels content strategy, saving time and ensuring consistent posting.
