Requires the `webhooks:write` scope. ## OpenAPI ````yaml /openapi.yaml delete /webhooks/{id} openapi: 3.0.3 info: title: QRKit API description: > Programmatic access to QRKit — create, manage and track QR codes. All requests are scoped to the **workspace** the API key belongs to: QR codes and folders created here appear in the QRKit dashboard and vice-versa. ## Dynamic vs static - **Dynamic** codes encode a short scan URL (`https://scan.useqrkit.com/{short_code}`) that redirects to your destination — editable later, with scan analytics. Types: `url` (default), `vcard`. - **Static** codes encode their payload directly — nothing to host, but the content is fixed once printed and there are no analytics. Types: `wifi`, `email`, `sms`, `text`, `event` (always static), and `url` when created with `"type": "static"`. Dynamic codes have ids like `qr_123`; static codes `sqr_123`. version: '2026-02-08' contact: email: support@useqrkit.com servers: - url: https://api.useqrkit.com/v1 description: Production - url: http://localhost:3001/v1 description: Local development security: - bearerAuth: [] tags: - name: Webhooks description: > Webhook endpoints receive HTTP POST notifications whenever events occur in your workspace. Each endpoint subscribes to one or more event types (or `*` for all). Requires API key scopes `webhooks:read` and/or `webhooks:write`. Endpoint caps are counted per `source`: up to 10 endpoints created directly (`source: "api"`, the default) plus up to 50 for each integration platform (`zapier`, `make`, `n8n`) — integrations register one endpoint per active Zap/scenario and manage their own. ## Event catalog | Type | Fires when | |------|-----------| | `qr.created` | A QR code is created via API or dashboard | | `qr.updated` | A QR code's name, target, design, tags or active state changes | | `qr.deleted` | A QR code is deleted | | `qr.scanned` | A dynamic QR code is scanned (see privacy guarantee below) | | `batch.completed` | All items in a batch job have finished processing | | `batch.failed` | A batch job failed globally (not item-level errors) | | `ping` | Emitted only via `POST /webhooks/{id}/test` to verify connectivity | ## Event envelope Every delivery sends a JSON body with the shape: ```json { "id": "evt_…", "object": "event", "type": "qr.scanned", "created_at": "2026-06-11T12:34:56.789Z", "data": { … } } ``` Events are addressable via `GET /v1/events/{id}` for 30 days after creation. Re-fetch authoritative object state via the REST API if you need fields beyond what the event payload includes — event ordering is not guaranteed. ## Signature verification Every delivery includes the header: ``` QRKit-Signature: t=1718099696,v1=a3b2c1… ``` The signed string is `"{t}.{raw_request_body}"`. Compute `HMAC-SHA256` over that string using your endpoint secret (`whsec_…`). Compare the result against the `v1=` value using a **constant-time** equality function. Reject deliveries where the timestamp `t` differs from your server clock by more than **5 minutes** to prevent replay attacks. During the 24-hour grace period after a `rotate-secret` call the header will contain two `v1=` entries (one for each secret). Accept a delivery if **either** value matches. ## Retry schedule Failed deliveries (non-2xx response, timeout, or connection error) are retried up to 7 attempts on an exponential back-off schedule: | Attempt | Delay after previous | |---------|---------------------| | 1 | immediate | | 2 | 1 minute | | 3 | 5 minutes | | 4 | 30 minutes | | 5 | 2 hours | | 6 | 6 hours | | 7 | 24 hours | After the 7th failed attempt the delivery moves to terminal `failed` status (~33 hours total window). ## Auto-disable After sustained delivery failures the endpoint is automatically set to `auto_disabled` and an email is sent to the workspace owner. Re-enable it by calling `PATCH /v1/webhooks/{id}` with `{ "status": "enabled" }` once your server is healthy (consecutive failure count resets to zero on re-enable). ## Delivery semantics - **At-least-once** — the same event may be delivered more than once; deduplicate by the event `id`. - **30-day retention** — events and delivery records are kept for 30 days. - **Ordering not guaranteed** — process events idempotently and re-fetch authoritative state via REST or `GET /v1/events` when you need a consistent view. ## qr.scanned privacy guarantee Scan events delivered to external endpoints contain **no IP address**, **no precise location** (no latitude, longitude, or postal code), and **no raw user-agent string**. The `data` payload is limited to: `country`, `city`, `device`, `os`, `browser`, `referrer`, and `language`. - name: Events description: > Read-only access to the event archive.
