  title: Temenos Microservices Define And Execute Orchestration
  summary: Define a service orchestration sequence and trigger its execution.
  description: >-
    Service orchestration flow on the Temenos Banking Microservices platform.
    The workflow registers a named orchestration sequence describing the
    ordered service calls to chain, then triggers execution with input
    parameters and branches on the reported execution status, surfacing whether
    the run started, is in progress, or failed to launch. Every step inlines
    its request so the chain is self-describing.
