The Send Connection Request endpoint creates an async task to send a LinkedIn connection request from your team’s oldest admin member’s LinkedIn account. The API itself only creates the task; the browser extension performs the LinkedIn action.

​
Endpoint

POST https://api.outx.ai/linkedin-agent/send-connection-request

​
Request Body

​
profile_urn
string
required
LinkedIn profile URN for the invitee (a urn:li:fsd_profile:... string). You can also pass the URN without the urn:li:fsd_profile: prefix — the plugin will normalize it.

​
Response

The endpoint returns immediately with a task ID:
​
success
boolean
Whether the task was created successfully
​
api_agent_task_id
string
UUID to poll for results via Get Task Status
​
message
string
Human-readable confirmation
{
  "success": true,
  "api_agent_task_id": "550e8400-e29b-41d4-a716-446655440000",
  "message": "Send connection request task created successfully"
}

​
Polling for Results

Poll the Get Task Status endpoint until the status is completed: 
GET https://api.outx.ai/linkedin-agent/get-task-status?api_agent_task_id=550e8400-e29b-41d4-a716-446655440000

​
Completed Response

When the task finishes, task_output will include: 
{
  "sent": true
}

FAQ

The connection request is executed from your team’s oldest admin member’s LinkedIn account (sorted by when they joined the team).
No. This endpoint only supports sending the connection invitation without an optional personalized message.
Use a LinkedIn fsd_profile URN (for example: urn:li:fsd_profile:ACoA...). If you omit the urn:li:fsd_profile: prefix, the plugin will normalize it automatically.
