Persona Webhooks

Persona Webhooks

When to Use This Skill

• How do I receive Persona webhooks?
• How do I verify the Persona-Signature header?
• Why is my Persona webhook signature verification failing?
• How do I handle inquiry.completed, inquiry.approved, or verification.passed events?
• How do I parse Persona's JSON:API webhook payloads?

Verification (core)

Persona has no official server-side SDK — verify the Persona-Signature header manually. It is a Stripe-style scheme (NOT Standard Webhooks): the header is t=<unix_seconds>,v1=<hex>, and v1 is an HMAC-SHA256 hex digest over `${t}.${rawBody}` keyed with the per-webhook secret (wbhsec_...). Use the raw request body — never JSON.parse first. During secret rotation the header carries two space-separated t=...,v1=... pairs; accept if any v1 matches.

const crypto = require('crypto');

function verifyPersonaSignature(rawBody, header, secret) {
  if (!header) return false;
  // Rotation: header may hold two space-separated "t=...,v1=..." pairs.
  return header.trim().split(/\s+/).some((pair) => {
    const parts = pair.split(',');
    const t = parts.find((p) => p.startsWith('t='))?.slice(2);
    const v1 = parts.find((p) => p.startsWith('v1='))?.slice(3);
    if (!t || !v1) return false;
    const expected = crypto.createHmac('sha256', secret)
      .update(`${t}.${rawBody}`).digest('hex');
    const a = Buffer.from(v1, 'hex');
    const b = Buffer.from(expected, 'hex');
    return a.length === b.length && crypto.timingSafeEqual(a, b);
  });
}

Persona documents no timestamp tolerance — signature validity is the check. Add your own replay window only if you need one. See references/verification.md for the Python version, rotation details, and gotchas.

Payload Shape

Persona webhook bodies are JSON:API envelopes. The important paths:

Each webhook is pinned to a configurable API version, which fixes the payload schema.

Common Event Types

For the full event list, see Persona Events.

Environment Variables

# Persona webhook signing secret (wbhsec_...)
# Dashboard -> Webhooks -> select your webhook -> reveal the secret
PERSONA_WEBHOOK_SECRET=wbhsec_your_webhook_secret_here

Local Development

# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 persona --path /webhooks/persona

Then create a test inquiry in the Persona Dashboard, or use Webhooks → Recent events → Resend to redeliver a past event (events are retained for 30 days).

Recommended: webhook-handler-patterns

We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Persona delivers duplicates and does not guarantee ordering, so idempotency matters. Key references (open on GitHub):

• Handler sequence — Verify first, parse second, handle idempotently third
• Idempotency — Prevent duplicate processing (key on data.id)
• Error handling — Return codes, logging, dead letter queues
• Retry logic — Provider retry schedules, backoff patterns
