AI voice campaigns, controlled by API.

How a broadcast runs.

Four calls take a campaign from draft to a downloadable report. The window, the retries, and the voicemail handling run themselves in between.

1. POST /v1/broadcastsCreate the campaign: a published agent, a prompt template with {{variables}}, a start phrase, the calling window, and the retry policy. It's a draft — nothing dials yet.
2. POST /v1/broadcasts/{id}/contactsAdd contacts as JSON, or upload a CSV to /contacts/bulk. Each row is a phone number plus the variable values that personalize its call — a bad row is rejected individually with the reason, never the whole batch.
3. POST /v1/broadcasts/{id}/startStart it, then walk away. Dialing runs only inside your window, misses re-queue per your retry policy, and /pause and /resume are one call each if plans change.
4. GET /v1/broadcasts/{id}/report.csvDownload the report: one row per call with its outcome — and every result is backed by the call's own recording and per-turn transcript.

Every broadcast endpoint — including /duplicate for re-running a campaign on a new list — is documented in the API reference.

Create and control campaigns by API

Create the campaign, add contacts, start or pause it, and download the report with documented endpoints.

Send one test call before a campaign.

POST /v1/agents/{id}/send places a single agent call with the same prompt template and variables a broadcast uses. Hear the exact conversation your contacts will get, tweak the template, then hand it to a broadcast and a contact list.

await fetch(`https://api.sautikit.com/v1/agents/${agentId}/send`, {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.SAUTIKIT_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    to: "+254712345678",
    prompt_template:
      "You are calling {{name}} to confirm Tuesday's appointment.",
    variables: { name: "Alice" },
  }),
});

Campaign use cases.

If a team reads the same script down a list every month, a broadcast does it with a template and an agent — and brings back what each person actually said.
