Qlik Talend Cloud: How to Change the Value of Context Parameters and Propagate the Change to all Tasks?

[FangZhen_TAO]

For Qlik Talend On-premises Solution, when using global context values in all jobs, If you want to change the file path values to replace d:/ with t:/, you can propagate the change to all jobs in the Studio.

 
How about Qlik Talend Cloud and Hybrid Solutions? This article provides a brief introduction to changing the value of context parameters and propagating the change to all Tasks in Talend Cloud.

How To

You can use this API to update artifact parameters

Put https://api.eu.cloud.talend.com/orchestration/executables/tasks/{taskid}

In the body, set the paramters you want to update:

Example: change the ContextFilePath": from "C:/Franking/in.csv" to  "h:/Franking/in.csv")

{
 "name": "contextpath",
 "description": "CC",
 "workspaceId": "61167bef18d7d656bfae071d",
"artifact": {
   "id": "689b5d04febbe74489779c31",    
   "version": "0.1.0.20251208032554"
 },
 "parameters":{
"ContextFilePath": "h:/Franking/in.csv"
}
}

To maintain context values better in the long run for multiple jobs, create a Connection in Talend Cloud. This way, all context in the job can be updated by updating the file name in the Qlik Talend Management Console Connection as opposed to running the API multiple times. For information on how to set up a connection, see Managing connections.
