I think the easiest way is to interpolate the variables in the (frontend) data source plugin, and pass them to the backend plugin. Since the backend plugin isn’t running in the browser, you need to pass any dependencies you need.

Thanks. I can do it using

import { getTemplateSrv } from '@grafana/runtime';

the @grafana/runtime canary version including the latest code of grafana, lincluding applyTemplateVariables.

Done. thanks grafana, great tool!
