Hi Suhas,

from where are you trying to query this information? Does this help?
https://docs.camunda.org/manual/latest/reference/rest/history/variable-instance/get-variable-instance/

https://docs.camunda.org/manual/latest/reference/rest/history/variable-instance/post-variable-instance-query/

You POST
{{rest_url}}/history/variable-instance/?deserializeValue=false
with filter criteria in the JSON body. For instance:
{
“processInstanceId”:“da0e220e-0ae1-11ea-a5c4-00155d00d800”
}

Here is a postman collection with a working usage example:
