Schedule LinkedIn Post Drafts in n8n: GPT-4 + DALL·E + Telegram Approval

Generate LinkedIn post drafts in n8n—then get human approval in Telegram before publishing

This n8n workflow automatically creates a LinkedIn organization post draft every 23 hours for Foxtrot Tours using OpenAI, requests approval in Telegram, and—once approved—generates a realistic image with DALL·E-style tooling and publishes the post to LinkedIn.

What this workflow does

• Runs on a schedule (every 23 hours) using a Schedule Trigger.
• Uses OpenAI to generate content ideas for Foxtrot Tours in a structured format.
• Creates a complete LinkedIn post draft from the first topic, including an image description.
• Generates SEO-friendly LinkedIn hashtags using OpenAI based on the post title and content.
• Sends the draft + hashtags to Telegram and waits for an approval/reject decision from a human (approval message workflow prompt).
• Publishes only if approved: if approved, the workflow uses OpenAI’s gpt-image-1 to generate a realistic image from the description, then posts the content (with image) to a LinkedIn organization page via LinkedIn OAuth2.

Use cases

• Teams that want consistent LinkedIn publishing without risking unapproved AI content.
• Automation engineers building a human-in-the-loop review process for social media.
• SaaS operators managing organization pages who need draft-to-publish workflows with approvals in Telegram.

Technical details

• OpenAI: chat model (gpt-5.4) for topic ideas, post draft, and hashtag generation; gpt-image-1 for realistic image creation.
• Telegram: sends the approval request and reads the approve/reject decision (use a chat where humans can act—avoid bot-only chats).
• LinkedIn: OAuth2 posting to a configured LinkedIn organization ID.
• Nodes used: Schedule Trigger, LinkedIn, Telegram, if, Sticky Note, and n8nn8n-nodes-langchainagent (plus supporting flow logic).

Setup notes: add OpenAI credentials for the chat and image models, add Telegram credentials with the target chat ID, add LinkedIn OAuth2 credentials with permission to post as an organization, then adjust schedule/prompt content to match your brand voice.
