Smart APIFor recruiting

Candidate outreach, inside your ATS.

Recruiting platforms and talent teams use the Smart API to reach candidates on LinkedIn and email from the ATS or sourcing tool they already run. Candidates in, sequences out, replies back to the pipeline.

What you build on the Smart API

Source, then sequence

Search 1B+ profiles by title, seniority, company and country, or bring a Sales Navigator search or a CSV, then enroll the shortlist in one call.

InMail and email for passive candidates

Reach people outside your network with InMail, InMail open profiles without credits from Sales Navigator or Recruiter seats, and move to email when the candidate has an address.

Your pipeline stays current

The lead.status_changed, message.received and email.received webhooks move each candidate to the right stage in your ATS.

Four calls, then it runs on its own.

The Smart API queues, paces, retries and rotates every step once the campaign is live. Your code only handles what is specific to you.

  1. 1

    POST /database/people/search

    Find candidates

    Filters on titles, seniority, companies and countries. Each result returned uses AI credits.

  2. 2

    POST /campaigns

    Build the sequence

    Profile visit, InMail on open profiles, invitation otherwise, email as the fallback.

  3. 3

    POST /campaigns/{id}/leads

    Enroll the shortlist

    From your ATS by LinkedIn URL, or by email alone.

  4. 4

    POST /webhooks

    Sync the pipeline

    Replies and status changes update the candidate record on your side.

From search to sequence in two calls

api/v1
// Shortlist, then enroll in the candidate sequence
const { data } = await swarmhit.post("/database/people/search", {
  filters: {
    titles: ["Senior Backend Engineer", "Staff Engineer"],
    countries: ["Germany"],
  },
  limit: 25,
});
 
await swarmhit.post("/campaigns/" + CAMPAIGN_ID + "/leads", {
  leads: data.map((p) => ({ profileUrl: p.linkedinUrl, firstName: p.firstName })),
});

LinkedIn + email

Reach the passive ones, on the right channel.

Open profiles get an InMail (without credits from Sales Navigator or Recruiter seats, within LinkedIn's monthly allowance), everyone else gets a connection request, and candidates who never accept hear from you by email. One recruiter's accounts or a pool of them, and every reply lands in the same inbox.
