For developers and technical teams building on LinkedIn

LinkedIn outreach infrastructure for AI agents.

Plug your agents into the Swarmhit API and they converse directly on LinkedIn: connection requests, follow-ups, messages, and real replies, in real time. The LinkedIn layer is already built.

What your agents can do

Every native LinkedIn action, one API call away.

Agents trigger the same interactions a human would make, executed through infrastructure built for it.

Browse the full API reference

Converse through LinkedIn

messages.sendinbox.read

Agents read and write real LinkedIn conversations through the API. Two-way messaging with full thread history, and a human can take over at any point.

Send connection requests

connections.request

Targeted requests with personalized notes, sent within safe, human-like limits.

Run follow-ups

messages.sendsequences.attach

No reply after a few days? The agent decides the next touch, or hands the cadence to a Swarmhit sequence and watches the events.

Everything else LinkedIn supports

inmail.sendprofiles.visitposts.comment

Direct messages, InMail, profile visits, follows, post likes and comments, withdrawing stale invites. If Swarmhit supports it, your agent can trigger it.

Real-time events

Your agent knows the moment something happens.

Sending is half the job. Swarmhit pushes events back to your agent as they happen on LinkedIn, so it can decide the next move in real time: reply instantly, change the plan, escalate to a human, or update your CRM.

Most integration layers stop at endpoints. Here, agents receive events and orchestrate actions natively.

webhook deliveries

live
eventconnection.accepted
eventmessage.reply_received
eventconversation.status_changed

Delivered to your endpoint with full context.

Why not a generic API layer

The LinkedIn layer is the hard part. Ours is already built.

Generic APIs and integration layers hand you raw endpoints and leave LinkedIn's workflows, limits, and edge cases to your team. LinkedIn outreach is our whole product, so that layer already exists and runs in production every day.
