Schedule LinkedIn Posts with AI Content Generation and Telegram Approval

This n8n workflow automates the process of generating AI-powered content for LinkedIn posts, allows for human approval via Telegram, and then schedules the approved posts on LinkedIn. It provides a robust solution for content creators and marketers to streamline their social media presence with a human-in-the-loop validation step.

What it does

This workflow simplifies and automates the following steps:

1. Triggers Manually or on Schedule: The workflow can be initiated manually by clicking "Execute workflow" or automatically at predefined intervals using the Schedule Trigger.
2. Generates AI Content: It uses the OpenAI node to generate content for a LinkedIn post. The specific prompt and parameters for content generation are configured within the OpenAI node.
3. Formats Content: The generated AI content is processed by a Code node to format it appropriately for a LinkedIn post, likely adding a call to action or specific structure.
4. Prepares for Approval: An "Edit Fields (Set)" node prepares the data for the Telegram approval message, ensuring all necessary information (like the generated post content) is available.
5. Sends for Telegram Approval: A Telegram node sends the generated content to a specified Telegram chat for review and approval. This includes buttons for "Approve" or "Reject".
6. Waits for Approval: A "Wait" node pauses the workflow execution until a response is received from the Telegram approval message.
7. Routes Based on Approval: An "If" node checks the response from Telegram.
   • If Approved: The workflow proceeds to post the content on LinkedIn.
   • If Rejected: The workflow terminates, and the post is not published.
8. Posts to LinkedIn: If approved, a LinkedIn node publishes the generated content as a new post to the configured LinkedIn account.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance (self-hosted or cloud).
• OpenAI API Key: An API key for OpenAI to generate content.
• Telegram Bot Token and Chat ID: A Telegram bot and the chat ID of the group or user where approval messages will be sent.
• LinkedIn Account: A LinkedIn account with appropriate permissions to post content.
• n8n Credentials: Configure credentials for OpenAI, Telegram, and LinkedIn within your n8n instance.

Setup/Usage

1. Import the Workflow:
   • Download the provided JSON file.
   • In your n8n instance, click "Workflows" in the left sidebar.
   • Click "New" and then "Import from JSON".
   • Paste the JSON content or upload the file.
2. Configure Credentials:
   • Locate the OpenAI, Telegram, and LinkedIn nodes in the workflow.
   • Click on each node and select or create the necessary credentials.
     • For OpenAI: Provide your API key.
     • For Telegram: Provide your Bot Token and the Chat ID where approval messages should be sent.
     • For LinkedIn: Authenticate your LinkedIn account.
3. Customize Content Generation (OpenAI Node):
   • Open the OpenAI node.
   • Adjust the "Prompt" field to define how you want the AI to generate your LinkedIn post content (e.g., "Write a professional LinkedIn post about [topic]...").
4. Customize Content Formatting (Code Node):
   • Open the "Code" node.
   • Modify the JavaScript code to format the AI-generated content as desired (e.g., add hashtags, a specific closing, etc.).
5. Set Schedule (Optional):
   • If you want the workflow to run automatically, configure the "Schedule Trigger" node to your desired interval (e.g., daily, weekly).
6. Activate the Workflow:
   • Ensure all nodes are configured correctly.
   • Click the "Active" toggle in the top right corner of the workflow editor to enable it.
7. Run the Workflow:
   • Manually: Click "Execute workflow" in the top right corner to test it.
   • Automatically: If the Schedule Trigger is enabled, the workflow will run at the configured times.

Once running, you will receive a Telegram message with the generated post content. You can then approve or reject it, and the workflow will proceed accordingly.
