If you want to get a single historic process instance by ID, there is no need to query. Each instance represents a unique REST-resource. Just build up an URL using the ID:


GET history/historic-process-instances/{processInstanceId}

Hi i am newbie in Activiti, I am using 5.16.1 and when i call

GET history/historic-process-instances/{processInstanceId} the variables are empty and of course history/historic-process-instances/{processInstanceId}/variables does not work (neither {variableId} or {variableId}/data).

GET history/historic-process-instances?includeProcessVariables=true returns all the process instances with the variables included but i dont want to retrieve all the process instances stored.

The solution for me was to use the following REST api

GET history/historic-variable-instances?processInstanceId={processInstanceId}

But i consider that the first one should work, am I doing something wrong?

Thanks and regards.
Carlos.
