Integrations

Configure outbound webhooks from Settings → Integrations → Webhooks. ZRO delivers a signed POST request to your endpoint on each subscribed event.

Available events:

// Webhook payload envelope
{
  "id": "evt_xyz789",
  "event": "estimate.updated",
  "timestamp": "2026-04-20T14:32:00Z",
  "projectId": "proj_abc123",
  "data": {
    // Event-specific payload
  }
}

// Signature header for verification
X-ZRO-Signature: sha256=<HMAC-SHA256 hex digest>

const crypto = require('crypto');

function verifyWebhook(payload, signature, secret) {
  const expected = crypto
    .createHmac('sha256', secret)
    .update(payload, 'utf8')
    .digest('hex');
  return crypto.timingSafeEqual(
    Buffer.from(signature.replace('sha256=', ''), 'hex'),
    Buffer.from(expected, 'hex')
  );
}

Native ERP and accounting integration is in development. Configure outbound webhooks today to push estimate and cost data to any system that accepts HTTP POST.

ZRO generates accounting-compatible exports from any estimate or cost list:

All platform data is accessible via the REST API. Refer to the API reference for the full endpoint list. Common integration patterns:
