Where is the signature header?\n- How do I handle `Microsoft.EventGrid.SubscriptionValidationEvent`?\n- Why is my Event Grid event subscription stuck in `AwaitingManualAction` or `Failed`?\n- What is `WebHook-Request-Origin` / `WebHook-Allowed-Origin` and why is Event Grid sending me an HTTP OPTIONS request?\n- How do I authenticate Event Grid deliveries with a custom header, a query-parameter secret, or Microsoft Entra ID?\n- How do I parse `Microsoft.Storage.BlobCreated` from an Event Grid array vs a CloudEvents object?\n\n## There Is No Signature — Read This First\n\nEvent Grid is a managed pub/sub broker, not a single-vendor webhook signer.\n\n- **Event Grid does not sign the request body.** There is no `X-Signature`, no\n  HMAC, no shared signing secret, no timestamp+signature pair, no asymmetric\n  signature. **Do not write a `crypto.createHmac` / `hmac.new` verifier for\n  Event Grid** — there is nothing to verify against.\n- Security comes from two other things, and a production handler needs both:\n\n| Layer | What it proves | Mechanism |\n|-------|----------------|-----------|\n| **Handshake** (subscription time) | You own the endpoint and expected this subscription | `SubscriptionValidationEvent` echo, or the CloudEvents OPTIONS preflight |\n| **Channel auth** (every delivery) | The caller is who you configured | A static [delivery-property](references/verification.md) header you choose, a client secret in a query parameter, or a Microsoft Entra ID bearer token |\n\n- Because nothing is signed, there is **no raw-body requirement**. Parsing JSON\n  before authenticating is safe here in a way it never is for Stripe or Shopify.\n\n> If you are looking at Hookdeck's `AZURE_EVENT_GRID` source config and see HMAC\n> / Basic Auth / API Key options: those configure a header **you** attach via\n> Event Grid delivery properties. Azure computes no HMAC over the payload.\n\n## Two Handshakes — Which One Fires Depends on the Delivery Schema\n\n| Event subscription's delivery schema | Handshake | Method |\n|--------------------------------------|-----------|--------|\n| **Event Grid schema** (`eventgridschema`) | `Microsoft.EventGrid.SubscriptionValidationEvent` — echo the code | `POST` |\n| **CloudEvents v1.0 schema** (`cloudeventschemav1_0`) | CloudEvents abuse protection preflight | `OPTIONS` |\n\nVerbatim from the docs: *\"When you use the CloudEvents schema for output, Event\nGrid uses the CloudEvents v1.0 abuse protection **in place of** the Event Grid\nvalidation event mechanism.\"* Implement both — one handler, two paths.\n\n## Validation Handshake (core)\n\nEvent Grid POSTs a JSON **array** containing only the validation event, with\nheader `aeg-event-type: SubscriptionValidation`. Gate on\n`aeg-subscription-name` first: withholding the echo is how you deliberately\nfail validation for a subscription you did not create.\n\n```javascript\nconst VALIDATION_EVENT = 'Microsoft.EventGrid.SubscriptionValidationEvent';\n\n// Event Grid schema arrives as an ARRAY; CloudEvents as a single OBJECT.\nconst events = Array.isArray(body) ? body : [body];\nconst validation = events.find((e) => e && e.eventType === VALIDATION_EVENT);\n\nif (validation) {\n  const subscription = String(req.get('aeg-subscription-name') || '').toLowerCase();\n  // An attacker who learns your URL can point their own subscription at it.\n  if (!EXPECTED_SUBSCRIPTIONS.includes(subscription)) {\n    return res.sendStatus(403); // No 200, no echo => validation fails. Intended.\n  }\n  // MUST be 200 — \"HTTP 202 Accepted isn't recognized as a valid Event Grid\n  // subscription validation response\" — and must complete within 30 seconds.\n  return res.status(200).json({ validationResponse: validation.data.validationCode });\n}\n```\n\nThe documented response field is camelCase `validationResponse`. Microsoft's own\nC#/JS samples on the receive-events page emit PascalCase `ValidationResponse`;\nthe docs do not state whether matching is case-sensitive, so use the documented\ncamelCase form.\n\n## CloudEvents Abuse-Protection Preflight (core)\n\n```javascript\n// OPTIONS on the exact endpoint URI being registered. Consent is signalled by\n// the HEADERS, not the status code.\napp.options('/webhooks/azure-event-grid', (req, res) => {\n  const origin = req.get('WebHook-Request-Origin'); // e.g. eventemitter.example.com\n  if (!origin || !isAllowedOrigin(origin)) return res.sendStatus(403); // withhold consent\n  res.set('WebHook-Allowed-Origin', origin);       // or '*'\n  res.set('WebHook-Allowed-Rate', '120');          // requests per minute, or '*'\n  res.set('Allow', 'POST, OPTIONS');\n  res.sendStatus(200);\n});\n```\n\nThis handshake *\"doesn't aim to establish an authentication or authorization\ncontext\"* — it only proves the endpoint expects traffic. Channel auth still matters.\n\n## Channel Authentication (core)\n\nThe practical shared-secret path is a **static delivery property**: a custom\nheader you configure on the event subscription and compare server-side. Never\nname it with the reserved `aeg-` prefix.\n\n```javascript\nconst crypto = require('crypto');\n\nfunction checkDeliverySecret(received, expected) {\n  if (!expected) return false;            // Fail CLOSED when unconfigured.\n  const a = Buffer.from(String(received || ''));\n  const b = Buffer.from(expected);\n  if (a.length !== b.length) return false; // timingSafeEqual throws on length mismatch\n  return crypto.timingSafeEqual(a, b);\n}\n```\n\nThe second shared-secret path is a **client secret as a query parameter**. You\nappend it to the subscription's endpoint URL and *\"Event Grid service includes\nall the query parameters in every event delivery request to the webhook\"*:\n\n```bash\naz eventgrid event-subscription create ... \\\n  --endpoint \"https://example.com/webhooks/azure-event-grid?token=<secret>\"\n```\n\nAzure stores these encrypted, keeps them out of service logs and traces, and\nwithholds them when you read the subscription back unless you pass\n`--include-full-endpoint-url`.\n\n**Rotation is the trap.** The docs: *\"If you update the client secret, you also\nneed to update the event subscription. To avoid delivery failures during this\nsecret rotation, make the webhook accept both old and new secrets for a limited\nduration before updating the event subscription with the new secret.\"* So accept\na *list*, not a single value, and compare in constant time against every entry:\n\n```javascript\nfunction checkAgainstAny(received, expectedCsv) {\n  const accepted = String(expectedCsv || '').split(',').map((v) => v.trim()).filter(Boolean);\n  if (accepted.length === 0) return false;  // Fail CLOSED — \"unset\" is never \"allow all\".\n  // No early return: timing must not leak which secret in the set matched.\n  return accepted.reduce((hit, c) => checkDeliverySecret(received, c) || hit, false);\n}\n```\n\nDo not lowercase the accepted list while parsing it — secrets are\ncase-sensitive, and a shared `parseList` helper that normalises subscription\nnames will silently break secret comparison.\n\nFor Microsoft Entra ID protected endpoints, Event Grid *\"is now passing the\nMicrosoft Entra bearer token to the webhook client in every message. You need to\nvalidate the authorization token in your webhook.\"* Validate it as a normal JWT\nagainst your own Entra application (`jsonwebtoken` + `jwks-rsa`, or PyJWT +\n`PyJWKClient`) — see [references/verification.md](references/verification.md).\nMicrosoft does not publish the token's claim set, so do not hard-code claims.\n\n> **For complete handlers with both handshakes, all three channel-auth modes, schema normalisation, and tests**, see [examples/express/](examples/express/), [examples/nextjs/](examples/nextjs/), [examples/fastapi/](examples/fastapi/).\n\n## Message Headers\n\n| Header | Description |\n|--------|-------------|\n| `aeg-subscription-name` | Name of the event subscription — **check this** |\n| `aeg-delivery-count` | Number of attempts made for the event (retry signal) |\n| `aeg-event-type` | `SubscriptionValidation`, `Notification`, or `SubscriptionDeletion` |\n| `aeg-metadata-version` | Event Grid schema: metadata version. CloudEvents: the spec version |\n| `aeg-data-version` | Event Grid schema: data version. Not applicable for CloudEvents |\n| `aeg-output-event-id` | ID of the Event Grid event |\n\n`Content-Type` is `application/json; charset=utf-8` for Event Grid schema and\n`application/cloudevents+json; charset=utf-8` for CloudEvents schema.\n\n## Payload Shapes\n\n**Event Grid schema — a JSON array.** *\"Event Grid sends the events to\nsubscribers in an array that has a single event.\"* Batching is off by default\nbut configurable up to 5,000 events, so **always loop**.\n\n```json\n[{ \"topic\": \"/subscriptions/...\", \"subject\": \"/blobServices/default/containers/c/blobs/f.jpg\",\n   \"eventType\": \"Microsoft.Storage.BlobCreated\", \"id\": \"aaaa0a0a-...\",\n   \"data\": { \"api\": \"PutBlob\", \"url\": \"https://...\", \"contentLength\": 52577 },\n   \"dataVersion\": \"\", \"metadataVersion\": \"1\", \"eventTime\": \"2024-12-06T03:32:15.7238874Z\" }]\n```\n\n**CloudEvents v1.0 schema — a single JSON object** with `specversion`, `type`,\n`source`, `id`, `time`, `subject`, `data`. Normalise both:\n`eventType`→`type`, `eventTime`→`time`, `topic`→`source`.\n\n## Event Types\n\nEvent Grid is a broker: **most event types belong to the publishing service or\nto a custom topic whose publisher defines them**, not to Event Grid itself.\n\nEmitted by the `Microsoft.EventGrid` resource provider:\n\n| Event type | Data |\n|-----------|------|\n| `Microsoft.EventGrid.SubscriptionValidationEvent` | `validationCode`, `validationUrl` |\n| `Microsoft.EventGrid.SubscriptionDeletedEvent` | `eventSubscriptionId` |\n| `Microsoft.EventGrid.MQTTClientCreatedOrUpdated` | Event Grid Namespaces / MQTT broker |\n| `Microsoft.EventGrid.MQTTClientDeleted` | Event Grid Namespaces / MQTT broker |\n| `Microsoft.EventGrid.MQTTClientSessionConnected` | Event Grid Namespaces / MQTT broker |\n| `Microsoft.EventGrid.MQTTClientSessionDisconnected` | Event Grid Namespaces / MQTT broker |\n\nRepresentative publisher event types (attributed to their publisher):\n`Microsoft.Storage.BlobCreated`, `Microsoft.Storage.BlobDeleted` (Azure Blob\nStorage); `Microsoft.Resources.ResourceWriteSuccess`,\n`Microsoft.Resources.ResourceDeleteSuccess`,\n`Microsoft.Resources.ResourceActionSuccess` (Azure subscription / resource\ngroup). See [references/overview.md](references/overview.md).\n\n## Delivery Semantics\n\n- **HTTPS only.** *\"Event Grid supports only HTTPS webhook endpoints.\"*\n- **Success codes — only these**: `200`, `201`, `202`, `203`, `204`. Everything\n  outside 200–204 is a failure. (Note the contrast with the validation\n  handshake, where **202 is explicitly not accepted**.)\n- **30-second timeout.** Exceeding it queues the message for retry — ack fast,\n  process asynchronously.\n- **Not retried for webhooks**: 400, 401, 403, 413.\n- **Backoff**: 10s, 30s, 1m, 5m, 10m, 30m, 1h, 3h, 6h, then every 12h up to 24h.\n- **At-least-once, unordered.** Duplicates happen — **dedu","tagline":"Receive and validate Azure Event Grid webhook deliveries.
