# get_post_engagers: Get who engaged with a post

List who reacted to and who commented on one post, together. This action only reads; it changes nothing. Plan: Free and Connect.

```
POST https://api.heyreagent.com/v1/actions/get_post_engagers
Authorization: Bearer YOUR_KEY
content-type: application/json

{
  "postUrl": "PASTE_POST_LINK_HERE"
}
```

## What you give it

- `postUrl` (needed): a post link or a post social id. The LinkedIn post URL (activity/share/ugcPost URL). Where to get it: On LinkedIn, click the More icon (the three dots) at the top right of the post, then "Copy link to post". Or: Run `search_posts` and use `posts[].url`.
- `connectionId` (optional): a connection id. Which sender to read through. Omit to use the first live sender. Where to get it: Run `list_linkedin_accounts` and use `accounts[].id`.
- `maxReactions` (optional): a number, 1 to 100. Max reactors (likers) to return (1–100, default 100).
- `maxComments` (optional): a number, 1 to 100. Max commenters to return (1–100, default 100).

## What you get back

- `summary`
- `reactors`
- `commenters`
- `note`

## Good to know

- At most 100 of each, with no next page. list_post_reactions and list_post_comments page through all of them.
- postUrl takes the post's link or its socialId. A bare post id is refused.
- The code that reads commenters says its field names were inferred and not checked against a real answer.
