n8n Workflow: Instagram Reels Creation with GPT-4o Mini and Sisifai

This n8n workflow automates the creation of content for Instagram Reels by leveraging AI to generate ideas and then interacting with a custom API, likely Sisifai, to manage the actual reel creation process. It's designed to streamline content production, making it easier to consistently post engaging short-form video content.

What it does

This workflow performs the following key steps:

1. Triggers on a Schedule: The workflow is set to run periodically, indicating a regular content generation schedule.
2. Generates Content Ideas with AI:
   • It uses a "Basic LLM Chain" to interact with an "OpenAI Chat Model" (likely GPT-4o Mini, given the directory name context).
   • The AI is prompted to generate a list of Instagram Reel ideas, including a short title, a detailed description, and a list of hashtags. The prompt specifies the desired output format as JSON.
3. Parses AI Output: A "Structured Output Parser" node processes the JSON output from the AI, ensuring the data is correctly structured for subsequent steps.
4. Prepares Data for API Call: A "Function" node likely transforms or refines the AI-generated data into the exact format required by the Sisifai API.
5. Checks for Previous API Calls (Placeholder): An "If" node is present, but without connections, it currently acts as a placeholder for potential conditional logic. In a complete workflow, this might check if a similar reel has been created recently or if the idea meets certain criteria.
6. Sends Request to Sisifai API: An "HTTP Request" node makes a POST request to a specified URL (likely the Sisifai API endpoint) to initiate the Instagram Reel creation. It sends the AI-generated content (title, description, hashtags) in the request body.
7. Waits for API Processing: A "Wait" node introduces a delay, allowing the Sisifai API time to process the reel creation request before any potential follow-up actions (though none are explicitly connected in this JSON).
8. Sets Fields (Placeholder): An "Edit Fields (Set)" node is present but not connected, suggesting a potential future step to modify or add fields based on the API response or for further processing.
9. Provides Documentation: A "Sticky Note" node serves as an in-workflow comment or documentation.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance to import and execute the workflow.
• OpenAI API Key: Configured as an n8n credential for the "OpenAI Chat Model" node to access GPT-4o Mini.
• Sisifai API Access: An API endpoint and any necessary authentication (e.g., API key, bearer token) for the Sisifai service to create Instagram Reels. This would be configured in the "HTTP Request" node.

Setup/Usage

1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
2. Configure Credentials:
   • Set up your OpenAI API Key credential in n8n.
   • Configure the "HTTP Request" node with the correct Sisifai API endpoint and any required authentication (e.g., API key in headers or body).
3. Review and Adjust:
   • Examine the "Schedule Trigger" node and adjust the cron expression to your desired frequency for generating and creating reels.
   • Review the prompt in the "Basic LLM Chain" node to ensure the AI generates content aligned with your brand and target audience.
   • Verify the "Function" node's code to ensure it correctly transforms the AI output for the Sisifai API.
   • If you wish to add conditional logic, connect the "If" node and define its conditions.
   • Adjust the "Wait" node's duration as needed based on the expected processing time of the Sisifai API.
4. Activate the Workflow: Once configured, activate the workflow to start automating your Instagram Reel creation.
