Matcher reads the key only from this header, and only when you send one. A request that carries a key only in `X-Idempotency-Key` or `Idempotency-Key` is refused with `400` (`MTCH-0015`), and nothing is processed. If the same key is sent again and the original request was already processed, the stored response is returned with `X-Idempotency-Replayed: true`. A malformed key returns `400`, a key whose first request is still in progress returns `409` (`MTCH-0018`), a key whose earlier attempt already ran but whose answer cannot be replayed returns `409` (`MTCH-0022`), and an idempotency storage failure returns `500`. POST, PUT, PATCH and DELETE requests accept the header. These refusals are problem documents. schema: type: string schemas: DispatchRequest: additionalProperties: false properties: queue: description: Optional queue or team assignment examples: - RECON-TEAM maxLength: 255 type: string targetSystem: description: Target system to dispatch to enum: - JIRA - SERVICENOW - WEBHOOK - MANUAL examples: - MANUAL maxLength: 255 minLength: 1 type: string required: - targetSystem type: object DispatchResponse: additionalProperties: false properties: acknowledged: description: Whether the target system acknowledged the dispatch examples: - true type: boolean dispatchedAt: description: Dispatch timestamp as an RFC 3339 timestamp examples: - '2025-01-15T10:30:00Z' type: string exceptionId: description: Identifier of the exception that was dispatched (UUID) examples: - 550e8400-e29b-41d4-a716-446655440000 type: string externalReference: description: Reference identifier returned by the target system examples: - RECON-1234 type: string target: description: External target system the exception was dispatched to examples: - JIRA type: string required: - exceptionId - target - acknowledged - dispatchedAt type: object Detail: additionalProperties: false properties: code: description: >- Stable, machine-readable domain error code scoped to the emitting service (format: -NNNN). examples: - ERR-0001 type: string detail: description: >- A human-readable explanation specific to this occurrence of the problem. examples: - Property foo is required but is missing. type: string errors: description: Optional list of individual error details items: $ref: '#/components/schemas/ErrorDetail' type: - array - 'null' instance: description: >- A URI reference that identifies the specific occurrence of the problem. examples: - https://example.com/error-log/abc123 format: uri type: string status: description: HTTP status code examples: - 400 format: int64 type: integer title: description: >- A short, human-readable summary of the problem type.
