Functions

create_flow_run

create_flow_run(flow_run: schemas.actions.FlowRunCreate, request: Request, db: PrefectDBInterface = Depends(provide_database_interface), response: Response = None, created_by: Optional[schemas.core.CreatedBy] = Depends(dependencies.get_created_by), orchestration_parameters: Dict[str, Any] = Depends(orchestration_dependencies.provide_flow_orchestration_parameters), api_version: str = Depends(dependencies.provide_request_api_version), worker_lookups: WorkerLookups = Depends(WorkerLookups)) -> schemas.responses.FlowRunResponse

Create a flow run. If a flow run with the same flow_id and idempotency key already exists, the existing flow run will be returned.

If no state is provided, the flow run will be created in a PENDING state.
