For developers and technical teams building on LinkedIn

LinkedIn outreach infrastructure for developers.

Build products, agents, and internal workflows on the Swarmhit API. Campaign logic, throttles, and account safeguards come built in, so you integrate in about a week instead of months.

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

Your product reads and writes 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? Your code 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 integration 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

eventconnection.accepted

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 providers expose raw LinkedIn actions and leave throttles, safeguards, and campaign logic to your team. Swarmhit runs that layer in production every day, which is why teams integrate in about a week instead of spending months debugging.

Build on raw APIs

  • Months of building and debugging raw actions
  • LinkedIn business logic yours to design, build, and maintain
  • Rate limits and account safety learned in production
  • Poll endpoints and reconcile state yourself
  • Scaling senders is your problem
  • White-label partial, if offered at all
  • API costs stack on top of your build cost
Production-ready in about a week
