Hi,

I just tested on the latest version. The `impersonateusername` parameter does work fine.

Make sure the username of the person using the impersonation is defined in the WorkflowGen main web.config’s parameter `ProcessesRuntimeWebServiceAllowedUsers` as indicated in the article [Web Services API: User Impersonation with ImpersonateUsername parameter](https://discuss.workflowgen.com/t/web-services-api-user-impersonation-with-impersonateusername-parameter/319/3).

e.g. `<add key="ProcessesRuntimeWebServiceAllowedUsers" value="wfgen_admin" />`

In this example, `wfgfen_admin` can impersonate `jsmith` when specifying `impersonateusername=jsmith` in the URL.
