Can we map a rule to a particular field only in work item?

[KamranAslamBhatti]

Hi, Is there a way we can map any rule to a specific field only, in the following command can we give field name so the rule myRule only fires/run when that particular field updated? As right now if any field updated the rule fires.

Current command aggregator-cli map.rule --verbose --project "myProject" --event workitem.updated --instance myInstance --rule myRule

Required command aggregator-cli map.rule --verbose --project "myProject" --event workitem.updated --instance myInstance --rule myRule --field System.Description

Thanks, Kamran

That's why we are going to introduce selfChanges, see example With this you can decide to skip your rule execution if a certain field was not changed. You can also get old and new value.

BUT: selfChanges is merged to master but you have to build and deploy the updated runtime in the install.instance command using the sourceUrl option.

The answer to the original question is no: the Web Hook mechanism has limited filtering features. You have to filter on the receiving side, i.e. the rule must use some if statement to check what changed as @BobSilent suggested.

Thanks Bob and giuliov for the prompt response.
