Smart APIFor sales teams

Your team’s outbound, wired into your stack.

RevOps and GTM engineers use the Smart API to run every rep's LinkedIn and mailboxes from the tools the team already works in: the CRM, n8n, Clay or an AI SDR. One call enrolls a lead, and every reply comes back as a webhook.

What you build on the Smart API

Campaigns triggered by your CRM

When a lead is ready, your workflow adds it to a campaign with one POST. Stage changes, scores and form fills turn into outreach without a rep copying anything.

Every rep's accounts, one pool

Each rep connects LinkedIn through a hosted link and their mailboxes from the dashboard. Campaigns rotate leads across the pool, inside each account's limits.

Replies back where the team works

The message.received and email.received webhooks carry every reply and its interest classification to your CRM, Slack or data warehouse.

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 /accounts/hosted-link

    Connect each rep's LinkedIn

    One link per rep. Passwords never reach you, and the result comes back on your return URL.

  2. 2

    POST /campaigns

    Create the team sequence

    LinkedIn and email steps, the sender pool, the mailbox pool and the sending schedule.

  3. 3

    POST /campaigns/{id}/leads

    Enroll from your CRM

    Up to 1,000 leads per call, by LinkedIn URL or by email alone.

  4. 4

    POST /webhooks

    Get every reply back

    Subscribe once. Sends, replies and bounces arrive signed.

// CRM workflow: a lead reached "Ready for outreach"
await swarmhit.post("/campaigns/" + CAMPAIGN_ID + "/leads", {
  leads: [{
    profileUrl: lead.linkedinUrl,
    email: lead.email,
    firstName: lead.firstName,
    company: lead.company,
    customVariables: { owner: lead.ownerName },
  }],
});
 
// replies come back on message.received and email.received

LinkedIn + email

One sequence per team, both channels.

Warm the lead on LinkedIn, invite, follow up once they accept. When they do not, the sequence checks for an email address and continues in the inbox, in the same thread. Each lead stays with one rep's sender and one mailbox.
