  title: Conductor Admin Task API
  description: Conductor is a workflow orchestration platform originally created by Netflix. It allows you to build complex applications using simple and granular tasks that do not need to be aware of or keep track of the state of your application's execution flow. Conductor keeps track of the state, calls tasks in the right order (sequentially or in parallel, as defined by you), retries calls if needed, handles failure scenarios gracefully, and outputs the final result. This API provides endpoints for managing workflow definitions, task definitions, workflow executions, task executions, and event handlers.
