Normalized call record

Voxfra normalizes each provider’s payload into a unified call record. This is what you see in the admin console and when querying the Management API.

Idempotency

Voxfra deduplicates webhooks by call ID within a 24-hour window. If your provider retries delivery:
  • The second request returns 200 immediately
  • No duplicate record is written
  • The duplicate: true flag is set in the response body
{
  "success": true,
  "requestId": "req_abc456",
  "duplicate": true
}
