HeyReagent / LinkedIn in n8n

LinkedIn in n8n: messages, invitations and search

n8n’s own LinkedIn node creates posts and nothing else. To send a message or an invitation, read your inbox or search people from a workflow, you call an API that does those on your own account. Here are the two ways to do that with HeyReagent, with what to type in each field.

What n8n's LinkedIn node does

One thing. n8n's documentation for the node says it "supports creating posts", and for anything else points to the HTTP Request node. n8n's documentation.

Way one: an HTTP Request node

Every action is one POST, so one HTTP Request node does one thing. First sign in, connect your LinkedIn, and create a key under Menu, then Developers. This sends a message:

MethodPOST
URLhttps://api.heyreagent.com/v1/actions/send_message
Send HeadersOn. Name Authorization, Value Bearer YOUR_KEY
Send BodyOn. Body Content Type JSON, Specify Body Using JSON, then paste the body below
{
  "profileUrl": "PASTE_PROFILE_LINK_HERE",
  "text": "Hello!"
}

The answer is { "ok": true, "result": { … } }, or { "ok": false, "error": "…", "message": "…" } with the reason in plain English. The actions n8n workflows use most:

Way two: the MCP Client Tool node, inside an AI agent

If your workflow has an AI Agent node, give it all the actions at once and let it choose:

https://api.heyreagent.com/mcp
n8nUses your key.
  1. Add an MCP Client Tool node to your agent.
  2. Endpoint: the address above. Server Transport: HTTP Streamable.
  3. Authentication: Bearer Auth, with your key.

Two workflows to start from

Each is a file you import: in n8n, open a new workflow, press the three dots at the top right, then Import from URL, and paste the address. Then put your key in a Bearer Auth credential, as the note inside the workflow says.

Find people and invite themSearch by plain words and a place, then send each person an invitation with your note. https://heyreagent.com/n8n/find-people-and-invite.json
Invite who reacted to a postPaste a post's link and invite the people who reacted to it. https://heyreagent.com/n8n/invite-post-reactors.json

Workflows people build

One action does one thing; a workflow is a few in a row, where the answer of one feeds the next. These are written out step by step, with the body of each call:

Before you put it on a schedule

On the free plan LinkedIn is disconnected after an hour without use. That is fine while you build and test, and it means a workflow that runs tomorrow morning will be told linkedin_disconnected. The Connect plan keeps LinkedIn connected, which is what a scheduled workflow needs.

The same call in curl, JavaScript and Python:

curl -X POST https://api.heyreagent.com/v1/actions/send_message \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "content-type: application/json" \
  -d '{"profileUrl":"PASTE_PROFILE_LINK_HERE","text":"Hello!"}'
The same call in JavaScript
const response = await fetch("https://api.heyreagent.com/v1/actions/send_message", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_KEY",
    "content-type": "application/json",
  },
  body: JSON.stringify({
    "profileUrl": "PASTE_PROFILE_LINK_HERE",
    "text": "Hello!"
  }),
});
const answer = await response.json();
console.log(answer);
The same call in Python
import requests

response = requests.post(
    "https://api.heyreagent.com/v1/actions/send_message",
    headers={"Authorization": "Bearer YOUR_KEY"},
    json={
        "profileUrl": "PASTE_PROFILE_LINK_HERE",
        "text": "Hello!",
    },
)
print(response.json())
The same call in n8n

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

MethodPOST
URLhttps://api.heyreagent.com/v1/actions/send_message
Send HeadersOn. Name Authorization, Value Bearer YOUR_KEY
Send BodyOn. Body Content Type JSON, Specify Body Using JSON, then paste the body below
{
  "profileUrl": "PASTE_PROFILE_LINK_HERE",
  "text": "Hello!"
}

Questions

Can n8n send LinkedIn messages?

Not with its own LinkedIn node, which only creates posts. It can with an HTTP Request node that calls an API which sends on your account, such as HeyReagent’s send_message action.

Is there an n8n LinkedIn node for outreach?

n8n’s built-in LinkedIn node has one operation, creating a post. For messages, invitations and search you use the HTTP Request node, or the MCP Client Tool node inside an AI agent.

Will a scheduled workflow run on the free plan?

Not reliably. On the free plan LinkedIn is disconnected after an hour without use, so a workflow that runs the next morning finds it disconnected. The Connect plan, at $29.99 a month, keeps it connected.

How many messages and invitations can a workflow send?

Each LinkedIn account has a daily limit for each kind of action: 100 messages and 80 invitations a day, for example. An action past its limit is refused, with the time it resets.

Is it safe for my LinkedIn account?

LinkedIn’s User Agreement does not allow automated activity, and LinkedIn can limit or restrict an account. The daily limits lower that risk. They do not remove it.

Sign in with your email, connect your own LinkedIn, and paste the address. No card. When you would rather it ran LinkedIn for you, that is the Agent plan.
