Call UpdateWorkflowDefinition API in DataStudio - DataWorks - Alibaba Cloud - DataWorks

Operation description

Important This API does not support batch operations. If you define more than one workflow definition in the FlowSpec, all workflow definitions except the first one are ignored. In addition, nodes defined within the workflow definition are also ignored. Call the UpdateNode API to update internal nodes one by one.

Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
ProjectId	integer	Yes	The DataWorks workspace ID. You can log on to the DataWorks console and go to the Workspace page to query the ID.	10001
Id	string	Yes	The unique identifier of the Data Studio workflow. Note This field is of the Long type in SDK versions prior to 8.0.0, and of the String type in SDK versions 8.0.0 and later. This change does not affect normal SDK usage; the parameter will still be returned according to the type defined in the SDK. However, compilation failures may occur due to the type change only when upgrading the SDK across version 8.0.0. In this case, you must manually update the data type.	652567824470354XXXX
Spec	string	Yes	The unique identifier of the Data Studio workflow. Note Prior to SDK version 8.0.0, this field is of type Long. In SDK version 8.0.0 and later, it is of type String. This change does not affect the normal use of the SDK. The parameter is returned based on the type defined in the SDK. However, compilation failures may occur due to the type change only when upgrading the SDK across version 8.0.0. In this case, you must manually update the data type.	{ "kind": "CycleWorkflow", "version": "1.1.0", "spec": { "workflows": [ { "id": "652567824470354XXXX", "script": { "path": "XX/OpenAPI_Test/Workflow_Test/OpenAPI_Test_Workflow_Demo", "runtime": { "command": "WORKFLOW" } }, "trigger": { "type": "Scheduler", "cron": "00 02 00 * * ?", "startTime": "1970-01-01 00:00:00", "endTime": "9999-01-01 00:00:00", "timezone": "Asia/Shanghai", "delaySeconds": 0 }, "strategy": { "timeout": 0, "instanceMode": "T+1", "rerunMode": "Allowed", "rerunTimes": 3, "rerunInterval": 180000, "failureStrategy": "Break" }, "name": "OpenAPI_Test_Workflow_Demo", "outputs": { "nodeOutputs": [ { "data": "workflow_output", "artifactType": "NodeOutput", "refTableName": "OpenAPI_Test_Workflow_Demo" } ] }, "dependencies": [] } ] } }
