The signing secret cannot be rotated through this endpoint; use the dedicated rotate-secret endpoint instead. ## OpenAPI ````yaml /openapi/openapi-integrations.json patch /integrations/api/v1/webhooks/endpoints/{endpoint_id}/ openapi: 3.1.0 info: title: Integrations API version: 1.0.0 description: > Webhook endpoint management and delivery tracking. ## Authentication All endpoints require an API key passed via the `X-API-Key` HTTP header, unless otherwise noted. ``` X-API-Key: csb__ ``` Generate API keys in **Settings > API Keys** in your dashboard, or via the Account API. Session-based (cookie) authentication is also accepted for browser-based access. ## Rate Limits | Tier | Requests / minute | Requests / day | |-------------|-------------------|----------------| | Default | 300 | 10,000 | | Custom | Contact us | Contact us | Rate-limit headers are included on every response so callers can self-throttle without hitting our 429s ("informed governor"): - `RateLimit-Policy` — every active window, e.g. `300;w=60, 10000;w=86400` - `RateLimit-Limit` — quota for the **most-restrictive** currently-active window - `RateLimit-Remaining` — requests left in that window - `RateLimit-Reset` — seconds until that window resets (relative; clock-skew safe) Legacy `X-RateLimit-*` aliases are also emitted for back-compat. `X-RateLimit-Reset` keeps the absolute Unix-timestamp shape to avoid breaking existing consumers. When rate-limited, you receive `429 Too Many Requests` with a `retry_after_seconds` field in the error envelope and a `Retry-After` header. ## Pagination List endpoints return paginated results in this envelope: ```json { "data": [...], "pagination": { "page": 1, "page_size": 25, "total_count": 342, "total_pages": 14, "has_next": true, "has_previous": false } } ``` Use `?page=2&page_size=50` query parameters. Maximum page size is 100. ## Error Responses All errors conform to [RFC 9457 Problem Details](https://www.rfc-editor.org/rfc/rfc9457) with `Content-Type: application/problem+json`: ```json { "type": "https://closient.com/docs/errors/not_found", "title": "Not Found", "status": 404, "detail": "The requested resource was not found.", "error_code": "not_found", "retryable": false, "timestamp": "2026-03-31T12:00:00+00:00" } ``` Common error codes: `unauthorized` (401), `forbidden` (403), `not_found` (404), `validation_error` (422), `rate_limited` (429), `internal_error` (500). termsOfService: https://www.closient.com/terms/ servers: - url: https://www.closient.com security: [] tags: - name: Webhook Endpoints description: Register and manage webhook delivery endpoints. - name: Webhook Deliveries description: Track and replay webhook delivery attempts. externalDocs: description: Closient Documentation url: https://docs.closient.com paths: /integrations/api/v1/webhooks/endpoints/{endpoint_id}/: patch: tags: - Webhook Endpoints summary: Update a webhook endpoint description: >- Partial update — every field on the request body is optional and omitted fields are left untouched. ``metadata`` follows Stripe-style merge semantics (``{}``/``null`` clears, empty-string values delete a key).

Verification recipe: compute ``HMAC-SHA256(secret, f"{timestamp}.{raw_body}")`` where ``timestamp`` is the ``t=`` portion of the header, then ``hmac.compare_digest`` against the ``v1=`` portion. Reject if the timestamp is older than 5 minutes (replay protection). During a 24-hour rotation grace period the header carries an additional ``v1old=`` signature using the prior secret — accept either. title: Signing Secret type: string event_types: description: >- List of event-type strings this endpoint subscribes to.
