Call it

curl -X POST https://api.heyreagent.com/v1/actions/get_post_engagers \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "content-type: application/json" \
  -d '{"postUrl":"PASTE_POST_LINK_HERE"}'

The same call in JavaScript

const response = await fetch("https://api.heyreagent.com/v1/actions/get_post_engagers", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_KEY",
    "content-type": "application/json",
  },
  body: JSON.stringify({
    "postUrl": "PASTE_POST_LINK_HERE"
  }),
});
const answer = await response.json();
console.log(answer);

The same call in Python

import requests

response = requests.post(
    "https://api.heyreagent.com/v1/actions/get_post_engagers",
    headers={"Authorization": "Bearer YOUR_KEY"},
    json={
        "postUrl": "PASTE_POST_LINK_HERE",
    },
)
print(response.json())

The same call in n8n

Add an HTTP Request node and fill it in like this:

Method	`POST`
URL	`https://api.heyreagent.com/v1/actions/get_post_engagers`
Send Headers	On. Name `Authorization`, Value `Bearer YOUR_KEY`
Send Body	On. Body Content Type `JSON`, Specify Body `Using JSON`, then paste the body below

{
  "postUrl": "PASTE_POST_LINK_HERE"
}

Put your own key where it says YOUR_KEY. Put your own value where it says PASTE_…_HERE: the table above says where each one comes from. New here? Start with your first call.

What you get back

When it worked, the answer is { "ok": true, "result": { … } }. Inside result:

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

A field that does not apply to an answer is left out, or is null.

When it did not work, the answer is { "ok": false, "error": "…", "message": "…" }. What each error means.

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.
