How to automatically claim a task as soon as it is opened

Jump to solution

/**This File is   "task-edit-header.js" which is used for the header of the task when a workflow is started.

There is a claim button on the top by clicking the button it will trigger "onClaimButtonClick" event and that event will call a function. So now what I want to do is as soon as the user opens a task it should automatically claim that task by calling that "onClaimButtonClick" event. 

Can anyone help me what I can do..? Thanks in advance

Hi @Rahul_Nathwani,

Could I just clarify your requirement? When a user clicks this button in a workflow, you want the that task to be claimed by what task?
