Quick overview
Quick overview This workflow runs daily to fetch your recent LinkedIn post reactions via a RapidAPI LinkedIn endpoint, uses OpenAI to turn each reacted post into a structured original content idea, and appends or updates the results in a Google Sheets idea vault without duplicates. How it works Runs every day at 08:00 using a schedule trigger. Loads configurable settings like your LinkedIn username, reaction type filter, recency window, max posts to analyze, OpenAI model, and output language. Calls the linkedin-api8 RapidAPI endpoint to retrieve posts you recently reacted to and splits the response into individual reaction items. Filters reactions to keep only the selected reaction type (or all when blank) and posts newer than the configured number of days. Limits the number of reactions sent for analysis to control cost. Sends each source post (author, reaction, text, and URL) to OpenAI to generate a structured content idea (category, angle, hook, takeaway, format, and hashtags). Saves each idea to Google Sheets using an upsert that matches on Post URL to avoid duplicate rows. Setup Create a RapidAPI subscription for linkedin-api8 and add an HTTP Header Auth credential that sends your x-rapidapi-key (and ensure the request includes the x-rapidapi-host header). Add an OpenAI API credential and set the model name in the configuration (for example, gpt-5-mini). Add a Google Sheets OAuth2 credential, set the target spreadsheet and sheet tab, and ensure your header row includes the mapped columns (including Post URL for matching). Update linkedin_username (and optionally reaction_filter, recency_days, max_ai_posts, and content_language) in the workflow configuration.
