My scenario is :
I want change history data of a work items which are modified in between 1 apr 2021 to 7 apr 2021 and I tried some REST API to fetch details but when I got response then I get only default attributes values I am not get customAttributes values even I change custom attributes as well, so my question is

1. can I get list of work items which modified in between 1 apr 2021 to 7 apr 2021 with REST API.

2. How can I get custom attribute values in response.

I tried following REST API to get change history of work items.

when I hit above URL then I get following response

<workitem Version="1.0.0" rel="next" href="https://localhost:9443/ccm/rpt/repository/workitem?id=_zXUqwJhHEeuAZLCPfd2uXg&fields=workitem%2FworkItem%5BprojectArea%2Fname%3D%22Tata%20Sky%20Business%20IT%20Requirement%20Management%22%20and%20modified%20%3E%202021-04-07T10%3A10%3A53.000-0500%5D%2F&size=100&pos=100"> <o:p> </o:p>

In above response I got change history of work item id 71 but I got only default attribute values not get customAttribute values so anyone can tell me how should I get custom attributes. 

Thanks in advance.

You may have more luck obtaining the information including custom attributes from JRS reports. Have you considered trying that? It may be that the REST API does not include the information for those custom attributes. You may want to tell us what version of RTC/EWM you have?

As far as I am aware, you can not change the history of the work item with public API. There is Java API to get the history states of a work item and its attributes, it is likely not exposed by a REST API. There is historical in reporting.

Note that ion an audited environment changing the history data would be forgery.
