LinkedIn

Configure the OwlStack WordPress plugin to publish posts to your LinkedIn personal profile or company page.

Prerequisites

You need a LinkedIn app with the appropriate API permissions.

Getting LinkedIn API Credentials

Go to the LinkedIn Developer Portal
Create a new app associated with your company page
Request access to the Share on LinkedIn and Sign In with LinkedIn products
Generate an Access Token using OAuth 2.0
Find your Person ID (for personal profiles) or Organization ID (for company pages)

Token Expiration

LinkedIn access tokens expire after 60 days. You'll need to refresh the token periodically. The plugin will report authentication errors when the token expires.

Settings

Navigate to OwlStack > LinkedIn in the WordPress admin.

Field	Description
Access Token	OAuth 2.0 access token
Person ID	Your LinkedIn member ID (for personal profiles)
Organization ID	Your company page ID (for company pages)

Person vs. Organization

Provide either a Person ID or an Organization ID, depending on whether you want to post from a personal profile or a company page. If both are provided, the Organization ID takes priority.

Step-by-step

Go to OwlStack > LinkedIn in your WordPress admin
Paste your Access Token
Enter your Person ID (for personal profile) or Organization ID (for company page)
Click Save Settings

Testing

After saving your settings:

Click Test Connection to verify your access token
Click Send Test Message to publish a test post
Check your LinkedIn profile or company page to confirm the post appeared

Publishing

Once configured, LinkedIn appears as a toggle in the OwlStack meta box on post edit screens.

Programmatic publishing

// Simple LinkedIn post
owlstack()->linkedin('Hello from WordPress!');

// Post with a link
owlstack()->linkedin('Check out our latest article: https://example.com/post');
