n8n Workflow: AI-Powered LinkedIn Content Automation

This n8n workflow automates the process of generating and posting LinkedIn content based on a schedule, leveraging AI for content creation and Google Sheets for content management. It also includes a Telegram notification system for approvals.

What it does

This workflow streamlines your content creation and publishing pipeline for LinkedIn:

  1. Scheduled Trigger: The workflow starts on a predefined schedule (e.g., daily, weekly).
  2. Google Sheets Integration: It reads a list of content ideas or prompts from a Google Sheet.
  3. Content Generation with AI: For each item from the Google Sheet, it uses an AI Agent (powered by OpenRouter Chat Model) to generate a LinkedIn post.
  4. Structured Output Parsing: The AI-generated content is then parsed to ensure it adheres to a structured format.
  5. Human-in-the-Loop Approval (Telegram): The generated content is sent to a Telegram chat for review and approval.
  6. Conditional Posting: If the content is approved via Telegram, it proceeds to be posted on LinkedIn.
  7. LinkedIn Posting: The approved content is automatically published as a post on LinkedIn.
  8. Error Handling/Logging: If any issues occur (e.g., content not approved), it logs the event (though the specific logging mechanism isn't explicitly detailed in the provided JSON, the "No Operation" node might be a placeholder for such logic).

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Google Sheets Account: A Google Sheet containing your content ideas/prompts.
  • OpenRouter API Key: An API key for the OpenRouter Chat Model (or any other compatible LLM service configured within the AI Agent node).
  • Telegram Bot Token: A Telegram bot and its token for sending and receiving approval messages.
  • LinkedIn Account: A LinkedIn account with appropriate permissions for posting.

Setup/Usage

  1. Import the workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Google Sheets: Set up your Google Sheets credential, linking it to the spreadsheet where your content ideas are stored.
    • OpenRouter Chat Model: Configure your OpenRouter API key within the "OpenRouter Chat Model" node.
    • Telegram: Set up your Telegram credential with your bot token and chat ID for approvals.
    • LinkedIn: Configure your LinkedIn credential to allow posting.
  3. Customize Google Sheet Node:
    • Specify the Spreadsheet ID and sheet name where your content ideas are located.
  4. Customize AI Agent:
    • Review and adjust the prompt in the "AI Agent" node to guide the content generation for LinkedIn posts.
  5. Configure Telegram Node:
    • Ensure the Telegram node is configured to send messages to the correct chat ID for approvals.
  6. Activate the Workflow: Enable the workflow to start running on its defined schedule.
  7. Monitor: Keep an eye on your Telegram chat for approval requests and your LinkedIn profile for automated posts.
