How To Use
To set up and run this powerful Instagram automation workflow, follow these steps:
- Set up Google Drive Credentials & Trigger Node:
- Configure your Google Drive credentials within n8n.
- In the "Post File Upload in Google Drive Folder Trigger" node, select the specific Google Drive folder you wish to monitor for new content. This node will activate automatically when new media (photo, video, or carousel) is uploaded.
- Configure Google Drive Download Node:
- Ensure your Google Drive credentials are set up.
- The "Post File Download in N8N (Google Drive Node)" will automatically download the uploaded file identified by the trigger into the n8n workflow.
- Set up OpenAI for AI Caption Generation:
- Set up your OpenAI API credentials in n8n.
- In the "AI Caption generated by OpenAI" node, select your desired OpenAI model (e.g.,
gpt-4o-mini). - Customize the prompt message to guide the AI in generating captions tailored to your brand's voice and content style, including desired emojis, hashtags, and calls-to-action.
- Set up Google Sheets (As indicated by creator's notes):
- While not present as an executable node in this specific JSON snippet, the creator's sticky notes strongly recommend adding a Google Sheets node for data management. Set up Google Sheets credentials.
- Create a Google Sheet with columns for "Name", "Caption", and "Image/Reel Link" to store and manage your post data. Integrate this sheet with an n8n Google Sheets node, connecting it to capture file details from Google Drive and captions from OpenAI.
- Configure Facebook Graph API for Instagram Posting:
- This is highlighted as the "Hardest Step" by the creator. Set up your Facebook Graph API credentials in n8n, ensuring you have the necessary permissions for your Instagram Business Account.
- You will typically need two Facebook Graph API operations: an initial node (often implied or preceding the final step) to create the media container on Instagram using the file downloaded from Google Drive and the caption from OpenAI, which returns a
creation_id. The subsequent "Finally Post to Instagram" node then uses thiscreation_idto publish the content to your selected Instagram Business account. Ensure thecreation_idparameter is correctly linked.
