Workflow Triggers

New Post Comment

Turn post engagement into pipeline — capture every commenter as a contact, connect with people engaging with your content, and run keyword-based follow-ups from a single post.

Trigger Overview

The New Post Comment Trigger runs when someone comments on the selected LinkedIn post. LinkedConnector checks periodically and fires the trigger once per new comment. Use it to capture commenters as contacts, send a connection request to people engaging with your content, or reply with a keyword-based follow-up.

💡
This trigger is not real time. New comments are polled in intervals throughout the day and released as they're found.

Use Cases

  • Comment-to-Lead Campaigns – "Comment PROMPT to receive our prompt pack." Filter by keyword and deliver the follow-up automatically
  • Contact Capture – Add everyone who comments on your post to your CRM
  • Engagement Outreach – Send a connection request to commenters who aren't in your network yet — they've already raised their hand
  • Comment Replies – Reply to comments automatically to keep the conversation (and the post's reach) going

Inputs and Required Data

This trigger uses filters to define what to monitor:

  • Page (required) – The LinkedIn page to monitor. This can be a personal profile or a business page
  • Post (required) – The specific post on that page to monitor for new comments
  • Keyword (optional) – Only fire when the comment text includes the keyword. Example: fire only on comments containing prompt for a "comment PROMPT to get the guide" campaign. Leave empty to fire on every new comment

Response

When activated, the trigger returns:

  • Comment ID – Identifier of the new comment
  • Post ID – Identifier of the monitored post
  • Post URL – Link to the monitored post
  • Provider ID – Internal LinkedIn identifier of the commenter
  • Full Name – Commenter's name
  • Profile URL – Link to the commenter's LinkedIn profile
  • Network Distance – Connection degree between your account and the commenter
  • Is Relationship – Whether the commenter is an existing connection
  • Comment – The text of the comment
  • Contact ID – ID of the matching contact in your CRM, if one exists

Contact ID is only populated when an existing contact in your CRM matches the commenter's Provider ID. If no matching contact exists, this field is empty — which is why every workflow built on this trigger starts with a find-or-create step.

⚠️
Important: Find or Create the Contact First Any follow-up LinkedIn actions in the workflow need a contact record to run against. Immediately after this trigger, add a Find Contact action (by ID) — and create the contact if none is found. Without this step, the actions that follow will get stuck.

Workflow Integration

Step-by-Step Example

A comment-to-lead campaign — deliver a resource to everyone who comments with your keyword:

  1. Trigger the Workflow
    • Start with the New Post Comment Trigger
    • Select the page and post to monitor, and set the keyword (e.g., prompt)
  2. Find or Create the Contact
    • Add a Find Contact action (by ID) using the Provider ID from the trigger payload
    • If a contact is found → Continue to your follow-up actions
    • If no contact is found → Create a new contact, then continue
  3. Reply to the Comment
    • Use Reply To A Comment to acknowledge them on the post (e.g., "Just sent it over!")
  4. Deliver the Follow-Up
    • Use the Is Relationship field to branch: existing connections get the resource by direct message, everyone else gets a connection request first

Monitoring the Trigger

You can confirm the trigger is registered and monitor it from the account dashboard:

  1. Open Sub-Accounts in the account dashboard
  2. Select the sub-account to open the Sub Account Details modal
  3. Under Workflow Triggers, each registered trigger is listed with its status — New Post Comment shows a green Active indicator when it's running

If New Post Comment isn't listed or doesn't show as Active, the trigger isn't registered. To register it:

  1. Delete the trigger from the workflow
  2. Save the workflow
  3. Refresh the page
  4. Re-add the trigger
  5. Save

Then check the dashboard again to confirm the trigger shows as Active.

  • Reply To A Comment – Respond to the comment directly on the post
  • React To A Comment – Acknowledge the comment with a reaction
  • Retrieve User Profile – Enrich the commenter's contact record with full profile data

Common Errors and Troubleshooting

Actions After the Trigger Get Stuck

  • Cause: No contact record was found or created before the follow-up actions ran
  • Solution: Add a Find Contact action (by ID) immediately after the trigger, and create the contact if none is found

Trigger Not Firing on Comments

  • Cause: A keyword filter is set and the comments don't contain it, or the wrong page or post is selected in the filters
  • Solution: Check the filters — confirm the page, the post, and whether a keyword filter is limiting what gets through

Contact ID Field Is Empty

  • Cause: No existing contact in your CRM matched the commenter's Provider ID
  • Solution: This is expected for new commenters. Create the contact in your find-or-create step and it will be linked from then on

Trigger Seems Delayed

  • Cause: New comments are polled in intervals throughout the day, not in real time
  • Solution: This is expected behavior. Build workflows around periodic delivery rather than instant response

Best Practices

  • Always find or create the contact immediately after the trigger — nothing downstream works without it
  • Tell people exactly what to comment. A specific keyword ("PROMPT") filters cleanly; vague asks ("interested?") don't
  • Reply on the post as well as in DMs — public replies keep the post active and visible
  • Use Network Distance and Is Relationship to branch your follow-up: message existing connections, invite everyone else
