Update And Trigger Flow

Trigger workflow scheduling with updated parameters (the information of the original workflow is not changed; the updated parameters are only used to generate a workflow instance).

Prerequisites

• The user must be the owner of the workflow.
• Both the user and the workflow are not locked.

Request Format

POST https://{apigw-address}/batch-processing-service/v2.1/flows

Request Parameters (URI)

Name	Location (Path/Query)	Mandatory/Optional	Data Type	Description

Request Parameters (Body)

Name	Mandatory/Optional	Data Type	Description

The workflow only allows one instance to run at any one time. If the pre-run instance conflicts with a running instance, it will be executed in sequence.
parameters	Mandatory	Map	The global parameters that are configured for the workflow to dynamically adapt to the environment changes (in the format of key=value). For more information, see Setting Parameters for a Workflow or SHELL-type of Task>>
