JavaScript / Node.js
// Trigger a call from any Node.js / browser app
const r = await fetch('https://outboundcalls.ai/api/v1/calls', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.OC_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    agentId: 'clxAGENT123',

const call = await r.json();
console.log(call.id, call.status); // RINGING

// Later β€” fetch transcript & summary
const detail = await fetch(`https://outboundcalls.ai/api/v1/calls/${call.id}`, {
  headers: { Authorization: `Bearer ${process.env.OC_API_KEY}` },
}).then(r => r.json());
console.log(detail.summary, detail.transcript);

Post-call webhook

Configure a webhook URL on each agent. After every call, OutboundCalls POSTs a signed JSON payload to your endpoint with:

  • Full transcript
  • Recording URL
  • AI-generated summary
  • Sentiment score
  • Goal achieved (true/false)
  • Extracted data fields
  • Duration + credits charged
  • Voicemail flag

All payloads are signed with HMAC-SHA256. Verify the X-Signature header against your agent's webhook secret.

Ship in minutes, not weeks

Create an account, generate an API key, and trigger your first call in under 5 minutes.
