URLs to backend

According to This Document the front end of a datasource connects to the backend at the path:

    return this.backendSrv.datasourceRequest({
      url: '/api/tsdb/query',
      method: 'POST',
      data: tsdbRequest

Is that regardless of the name of your specific backend? It just knows how to find the right backend gRPC server to route to?

As far as I know, yes. I’m not exactly sure how those parts operate, but that’s how the stuff I’m working on uses backendSrv.
