Wix Webhooks Skill

When to Use This Skill

• How do I receive Wix webhooks in a self-hosted app?
• How do I verify Wix webhook signatures (the JWT)?
• Where do I get my Wix public key to verify webhooks?
• How do I handle wix.ecom.v1.order_created / order_approved / order_canceled events?
• Why is my Wix webhook JWT verification failing?

How Wix Webhooks Work

Wix delivers each webhook as an HTTP POST whose entire request body is a signed JWT (RS256), signed by Wix. There are no X-Wix-Signature/HMAC headers and it is not Standard Webhooks — verification means validating the JWT with your app's public key.

• Get your public key from the app dashboard → Custom Apps → your app → Webhooks → "Get Public Key" (also under View ID & keys). It is per-app; there is no global JWKS endpoint.
• Verify against the raw, unparsed body. Re-serializing the JSON breaks the signature.
• The decoded JWT is a nested envelope: outer { data, iat, exp } → data is a JSON string → parse it to { eventType, instanceId, data } → parse the inner data string to get the entity/event payload.

Verification (core)

Node.js — official @wix/sdk verifies (RS256, via jose) and decodes in one call. Pass the raw text body:

import { AppStrategy, createClient } from '@wix/sdk';
import { orders } from '@wix/ecom';

const client = createClient({
  auth: AppStrategy({
    appId: process.env.WIX_APP_ID,
    publicKey: process.env.WIX_PUBLIC_KEY.replace(/\\n/g, '\n'), // PEM, or base64-encoded PEM
  }),
  modules: { orders },
});

// Register typed handlers up front...
client.orders.onOrderCanceled((event) => {
  console.log('Order canceled', event.metadata.entityId, 'event', event.metadata._id);
});

// ...then verify + dispatch the raw JWT body (throws if the signature/exp is invalid):
await client.webhooks.process(rawBody);

Python (no official server SDK) — verify the JWT manually with PyJWT + your public key:

import json, jwt  # PyJWT

def verify_and_decode(raw_body: bytes, public_key: str) -> dict:
    decoded = jwt.decode(raw_body, public_key, algorithms=["RS256"])  # raises on bad signature/exp
    event = json.loads(decoded["data"])          # -> { eventType, instanceId, data: "<json>" }
    event["entity"] = json.loads(event["data"])  # inner event/entity payload (has id, entityId, ...)
    return event

For complete handlers with route wiring, event dispatch, deduplication, and tests, see:

• examples/express/ — Node.js + @wix/sdk
• examples/nextjs/ — App Router + @wix/sdk
• examples/fastapi/ — manual PyJWT verification

Common Event Types

Event type strings follow wix.<product>.<version>.<entity>_<action>. Configure each one on the Webhooks page of your app dashboard.

See references/overview.md for more events and payload structure. For the full list, browse events alongside their API methods in the Wix API Reference.

Environment Variables

WIX_APP_ID=your-app-id            # OAuth page of your app dashboard
WIX_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----\n...\n-----END PUBLIC KEY-----"  # Webhooks > Get Public Key

Store the PEM public key on one line with \n escapes (the examples convert them back to newlines). A base64-encoded PEM also works with @wix/sdk.

Delivery, Retries & Idempotency

• Respond 200 within ~1250 ms or Wix retries — up to 12 more times over hours (1 min → 12 hours).
• Because of retries, events arrive out of order and duplicated. Dedupe on the event ID (event.metadata._id via the SDK, or the inner payload's id when verifying manually) and return 200 fast; do slow work asynchronously.
• Some legacy webhooks send only changed fields, not the full entity — GET the entity if you need the full object.

Local Development

# Start a tunnel (no account needed) and forward to your local handler
npx hookdeck-cli listen 3000 wix --path /webhooks/wix

Use the printed HTTPS URL (path /webhooks/wix) as the Callback URL when creating the webhook in your app dashboard.
