Quick overview

Get a Slack alert when target LinkedIn accounts post. Periodix Actions pulls recent posts from companies and people in a Google Sheet, skips seen posts, and Claude summarizes each with a comment angle and DM opener. One node instead of an Apify post scraper plus cookies.

How it works

  1. Every morning at 8:00 the workflow reads your target accounts from the Accounts tab and the posts you have already seen from the Posts tab.
  2. For each account without a stored author ID, Periodix resolves it once (Get Company Profile for company pages, Get Profile for people) and writes it back to the sheet, so later runs skip this step.
  3. Get User Posts pulls the latest posts for each account.
  4. New posts are kept only if they were not seen before, are not reposts (optional), and are newer than your age limit.
  5. Claude Haiku summarizes each new post, rates how relevant it is to what you sell, and suggests a comment angle and a DM opener.
  6. The post and the AI insight are saved to the Posts tab, and a Slack alert goes to your channel.

Setup

  1. Install the Periodix LinkedIn node (@periodix/n8n-nodes-actions) and connect your Periodix Actions API key. Start a 3-day free trial at actions.periodix.net.
  2. Create a Google Sheet with two tabs. Accounts: account_name, linkedin_url, author_id (leave author_id empty). Posts: post_id, social_id, account_name, linkedin_url, post_url, posted_at, text, reactions, comments, reposts, summary, relevance, why, comment_angle, dm_opener, slack_text, found_at.
  3. Add your target company pages and people to the Accounts tab.
  4. Connect Google Sheets, Anthropic, and Slack credentials, and choose your Slack channel.
  5. Edit Monitor Config: what_we_sell, posts_per_account, max_age_days, include_reposts.

Requirements

  • Periodix Actions account with a connected LinkedIn profile
  • Google Sheets account

Customization
