💡 Pro Tip — If you’re pulling LinkedIn data through HTTP requests or dealing with API restrictions, there’s a community node called ScraperNode that handles this natively. It has dedicated scrapers for profiles, companies, jobs, and people search — you just pass a URL and get structured data back.
Description
Quick overview
This workflow runs daily at 8 AM to rotate through a topic list, research it with Tavily web search, generate a LinkedIn post and image prompt with Groq (Llama 3.3 70B), create a Pollinations.ai image URL, and email you the post with the image attached via Gmail.
How it works
- Runs every day at 8:00 AM on a schedule.
- Selects today’s topic from a rotating list based on the day of the year.
- Searches the web with Tavily to fetch up-to-date results for the selected topic.
- Uses a Groq-hosted Llama model to write a LinkedIn post and a matching image prompt grounded in the Tavily results.
- Builds a Pollinations.ai image generation URL from the image prompt and downloads the generated image file.
- Emails the post text with the image attached via Gmail, and sends a text-only fallback email if image generation or download fails.
Setup
- Add a Groq API credential to the Groq Chat Model node.
- Create a Tavily API key and configure HTTP Header Auth with
Authorization: Bearer <YOUR_TAVILY_KEY>for the Tavily Search request. - Connect a Gmail OAuth2 credential and update the recipient email address in both Gmail send steps.
- Edit the topic list in the topic-selection code step if you want different rotating themes.
Requirements
- Groq API key (free tier available)
- Tavily API key (free tier — 1,000 searches/month)
- Gmail account (OAuth2)
Customization
- Edit the topic list inside the “Pick Today’s Topic” code node to change what subjects the post rotates through.
- Change the Groq model in the “Groq Chat Model” node if you want a different LLM (e.g. a smaller/faster or larger Groq model).
- Adjust the schedule trigger if you want a different posting time, or swap the Gmail “send to” address to deliver the draft to someone else for review.
Additional info
This workflow emails you a draft for manual review before posting — it does not post to LinkedIn automatically. If image generation fails, a text-only fallback email is sent instead so you never miss the post text.
