Overview

Pick events, verify HMAC signatures, handle retries idempotently, respond under 5 seconds, observe delivery. Five steps to a reliable webhook pipeline.

What You'll Learn

Webhooks let AnveVoice push real-time events to your backend — new leads, conversation endings, escalations, errors. A well-built webhook pipeline handles signatures, idempotency, retries, and observability. This guide walks through five steps to get it right: choosing events, deploying a signed endpoint, implementing idempotent handlers, responding fast, and monitoring delivery.

Key Points

• HMAC-SHA256 signature verification is mandatory, not optional
• Idempotency via event_id prevents double-processing on retries
• Sub-5-second response avoids webhook retries and backoff

Benefits

• Real-Time Event Push: Conversations, leads, and escalations push to your backend within seconds. No polling, no delay, no missed events.
• Signed and Secure: HMAC-SHA256 signatures verify every webhook. Rejected forgeries protect your pipeline from malicious or accidental replay.
• Automatic Retries: AnveVoice retries failed webhooks 6 times over 24 hours. Combined with your idempotent handler, zero events are lost.

Steps

• Step 1 — Choose Events to Subscribe: In AnveVoice > Webhooks > New, pick events: lead_captured (sync to CRM), conversation_ended (analytics), escalation_requested (support routing), low_confidence_response (product improvement), and system_error (engineering alerts). Only subscribe to events your backend actually processes — fewer events means cleaner pipelines.
• Step 2 — Deploy a Signed Endpoint: Deploy a POST endpoint at https://your-app.com/webhooks/anvevoice. On every request, compute HMAC-SHA256 of the raw request body using the secret AnveVoice shows you when you create the webhook. Compare the computed hash to the X-AnveVoice-Signature header with a constant-time comparison. Reject mismatches with 401.
• Step 3 — Handle Retries Idempotently: Every AnveVoice webhook payload includes event_id (UUID). Store processed event_ids in a deduplication table (Redis, database). On each incoming event, check if the event_id is already processed — if yes, return 200 without re-running your handler. AnveVoice retries failed webhooks 6 times over 24 hours; idempotency prevents duplicates.
• Step 4 — Respond Within 5 Seconds: AnveVoice marks webhooks as failed if your endpoint does not return 2xx within 5 seconds. Keep the handler lean: verify signature, dedupe, enqueue heavy work to a background job, return 200. Do NOT run CRM API calls, email sends, or analytics writes synchronously in the webhook handler.
• Step 5 — Monitor Delivery in the Dashboard: In AnveVoice > Webhooks > Delivery Log, every webhook attempt is logged with status, response code, latency, and retry count. Set up email/Slack alerts for 5xx spikes or retry rates above 1%. Replay failed webhooks manually with the Retry button if your endpoint was down during delivery.

Summary

Set up voice AI webhooks in 5 steps: pick events to subscribe (lead_captured, conversation_ended), deploy an endpoint that verifies HMAC-SHA256 signatures, handle retries idempotently with an event_id dedupe key, return 2xx within 5 seconds, and monitor delivery in the AnveVoice webhooks dashboard.

Verdict

Webhooks are the backbone of real-time voice AI integration. Five steps to a reliable pipeline with signature-verified, idempotent delivery.
