Automate LinkedIn Posts to Slack Using Zapier | Step-by-Step Guide

Keeping your internal teams informed about new LinkedIn posts is crucial for improving communication, strengthening brand alignment, and increasing overall engagement. However, manually copying and sharing every post to Slack can be repetitive and time-consuming.

This detailed guide explains how to automate the entire process using Zapier so that every new LinkedIn post automatically triggers a Slack message — without any manual effort.

Step 1: Create an RSS Feed for Your LinkedIn Company Page

Since LinkedIn does not provide a direct Zapier trigger for company page posts, we use an external tool — RSS.app — to create an RSS feed that Zapier can read.

Follow these steps:

Open RSS.app

Go to https://rss.app in your browser.
Log In or Create an Account

You’ll need to sign in. If it’s your first time, create a free account.
Create a New Feed

Once logged in, click Create New Feed.
This is where you will generate a custom RSS feed based on your LinkedIn company page.
Paste Your LinkedIn Page URL

Copy your LinkedIn company page URL from your browser’s address bar and paste it into the feed creation field.

Example:

https://www.linkedin.com/company/your-company-name/
Generate the Feed

Click Save or Create Feed.
RSS.app will scan your LinkedIn page and build an RSS feed out of the public posts on that page.
Copy the XML RSS Feed URL

Once the feed is generated, RSS.app provides an XML feed link such as:

https://rss.app/feeds/1234567890.xml

Paste your linkedin Url here

Then click on Save my feed this will generate a xm url.

Step 2: Create a Zap in Zapier

Zapier is the automation tool that monitors the RSS feed and sends messages to Slack.

Steps:

Log In to Zapier

Go to https://zapier.com and log in.
Create a New Zap

Click Create Zap from the dashboard.
Name Your Zap

Give your automation an identifiable name, such as:

“LinkedIn Post → Slack Notification”

Step 3: Configure the Trigger (RSS Feed)

This section tells Zapier when to start the automation.

Select Trigger App: RSS by Zapier

Use the search bar to find RSS by Zapier and select it.
Choose the Trigger Event

Select New Item in Feed.
This means Zapier will run whenever a new post appears in your RSS feed.
Paste the RSS Feed URL

In the field provided, paste the XML feed URL you copied from RSS.app.
Test the Trigger

Click Test Trigger.
Zapier will pull sample posts from the RSS feed to confirm the setup is working.
If the test is successful, move on to the next step.

Test Trigger

Step 4: Configure the Slack Action

Now that Zapier knows when to trigger, you must tell it what to do — post a message in Slack.

Add an Action

Click + Add Action.
Select the Slack App

Search for Slack and click on it.
Choose the Action Event

Select Send Channel Message.
Connect Your Slack Workspace

Zapier will ask for permission to post messages in your Slack workspace. Click Connect, then select the workspace, and allow access.
Choose the Slack Channel

Pick the Slack channel where you want LinkedIn post updates to appear. For example: #marketing, #announcements, or #all-employees.
Choose the Slack Channel

Pick the Slack channel where you want LinkedIn post updates to appear. For example: #marketing, #announcements, or #all-employees.
Format Your Slack Message

Use Zapier’s dynamic fields from the RSS feed, such as Title, Link, and Description.

Step 5: Publish the Zap

Once you're satisfied with your test:

Click Publish Zap.
Turn the Zap ON.

From this point forward, Zapier will automatically detect every new LinkedIn company post and instantly notify your Slack channel — without any manual work.

Conclusion

Automating your LinkedIn-to-Slack workflow ensures your entire organization stays updated on new company posts without requiring manual effort. This leads to:

Faster internal communication
Higher employee engagement on LinkedIn posts
Better alignment across marketing, HR, and leadership teams
Reduced manual workload

With this automation in place, your team never misses important updates again.
