Workflow Actions

React To A Post

Add a reaction (e.g., Like, Celebrate, Support, Insightful, Curious) to a LinkedIn post. Use this action to engage with content quickly and consistently as part of your outreach, brand visibility, or relationship-building workflows.

React To A Post

Action Overview

The React To A Post action allows you to respond to a LinkedIn post by applying one of LinkedIn’s supported reaction types. Reactions can be added as an individual user or, if authorized, on behalf of a company by providing the company’s Provider ID. This action is often paired with Retrieve Last Post or List All Posts to automate engagement with the most relevant content.

Use Cases

  • Sales Engagement – React to prospect updates to increase visibility and stay on their radar
  • Recruitment – Show support for candidate posts to build rapport before outreach
  • Brand Awareness – React as a company to industry news or client announcements to enhance brand presence
  • Relationship Building – Consistently engage with posts to strengthen ongoing connections

Inputs and Required Data

Post ID (required) – The identifier of the LinkedIn post you want to react to
Example: 78556533454663

Reaction Type (required) – The type of reaction to apply. Supported values:

  • Like
  • Celebrate
  • Support
  • Insightful
  • Curious

Company Provider ID (optional) – Add this to react as a company (must have permission to act on its behalf)
Example: 436356

Response

The React To A Post action returns:

  • Response – Confirmation of whether the reaction was successfully added

Example Response (plain text)

Obtaining Inputs

  • Use Retrieve Last Post or List All Posts to obtain the Post ID

  • Provide Company Provider ID if reacting as a company page

Workflow Integration

  1. Trigger the Action – Add React To A Post after retrieving a post to engage automatically
  2. Map Input Fields – Provide Post ID, select Reaction Type, and include Company Provider ID if applicable
  3. Process Results – Store confirmation in CRM activity logs to track engagement
  • Comment On A Post – Add a comment for deeper engagement beyond reactions
  • Retrieve Last Post – Get the most recent post from a user or company
  • List All Posts – Retrieve multiple posts for wider engagement opportunities

Common Errors and Troubleshooting

Invalid Post ID

  • Cause: The Post ID does not correspond to an existing post
  • Solution: Ensure the ID is retrieved from Retrieve Last Post or List All Posts

Invalid Reaction Type

  • Cause: A reaction type outside LinkedIn’s supported values was provided
  • Solution: Use only LinkedIn’s valid reactions: Like, Celebrate, Support, Insightful, Curious

Permission Error (Company Reaction)

  • Cause: User does not have authorization to react on behalf of the company
  • Solution: Confirm permissions are set for company page access

Best Practices

  • React consistently to posts from leads or clients to stay visible in their feeds
  • Choose reactions strategically (e.g., “Insightful” for thought leadership posts, “Celebrate” for milestones)
  • If using as a company, align reactions with your brand voice and guidelines

Advanced Tips

  • Layered Engagement – Pair with Comment On A Post for both quick visibility and meaningful interaction
  • Engagement Automation – Set workflows to react automatically to posts containing specific keywords or from target accounts
  • AI-Powered Reactions – Use post analysis with AI to suggest the most contextually appropriate reaction type
