InitiierungRequest

InitiierungRequest is a message type used within distributed systems to request the start of a new process or workflow. In a typical client–server interaction, the request is sent from an originator to a target service that owns or controls the resource to be initialised. The purpose is to convey the essential context and configuration needed to bootstrap the operation while enforcing security and traceability.

Structure and fields: Common fields include initiatorId, targetResource or endpoint, requestId, timestamp, version, and parameters. Optional fields can include authenticationToken, signature, and metadata. The parameters object carries initialization options such as configuration settings, initial state, or prerequisites.

Lifecycle: Upon receipt, the service validates the request: authenticates the initiator, verifies authorization, checks idempotency using requestId, and ensures prerequisites are met. If valid, it initiates the process and returns an InitiierungResponse indicating success and a new processId; otherwise, it returns an error description.

Security and handling: The message should be transferred over TLS and may be digitally signed to ensure integrity. Replay protection and proper access control are important.

Representations: Representations can be JSON, XML, or other protocol-specific formats; the choice depends on the system's API style (REST, gRPC, messaging).

Example: JSON snippet: { "initiatorId":"user-123", "targetResource":"ProvisioningService", "requestId":"req-456", "timestamp":"2025-12-10T12:34:56Z", "version":"1.0", "parameters":{"config":"default"}}
