How It Works

1. Task Creation

   When you call the Like API, a task is created and queued for processing

2. Validation

   The system validates:

   • Post exists and belongs to your team’s watchlists
   • User email is valid and associated with your team
   • Company title matches (if liking as company)
   • You haven’t exceeded plan limits
3. Asynchronous Processing

   The like is processed asynchronously by OutX’s automation system

4. Execution

   The like is performed on LinkedIn on behalf of the specified user or company

Actor Types Explained

User Actor Type

When actor_type is user:

• The like appears as coming from the individual user
• user_email should be the email of the user who will like the post
• The user must be part of your OutX team
• No company_title is needed

Use case: Personal engagement, building individual presence

Company Actor Type

When actor_type is company:

• The like appears as coming from your company page
• user_email should be the admin user’s email who manages the company page
• company_title must exactly match the company name on LinkedIn
• The admin user must have permission to manage the company page

Use case: Brand engagement, company visibility, B2B marketing

Frequently Asked Questions

How long does it take for a like to appear on LinkedIn?

Likes are processed asynchronously. Once you submit a like request, a task is created and queued. The like typically appears on LinkedIn within a few minutes, depending on when the Chrome extension processes the task. The extension must be active in a team member’s browser for the task to be executed.

Can I like posts from a company page?

Yes. Set actor_type to "company" and provide the company_title field with the exact company name as it appears on LinkedIn. The user_email should be the email of an admin user who has permission to manage that company page.
