title: querying across application insights resource with REST API
body: <p>I have data which are stored in 3 different application insights resources, thanks to <code>query across resource</code> feature added last year (<a href="https://azure.microsoft.com/en-us/blog/query-across-resources/" rel="nofollow noreferrer">https://azure.microsoft.com/en-us/blog/query-across-resources/</a>) was possible to query those 3 application insights at once with <code>app</code> identifier.</p>
  
  <p>I'm trying to execute this query through <code>app insights REST API</code> : <a href="https://dev.applicationinsights.io" rel="nofollow noreferrer">https://dev.applicationinsights.io</a> (app insights REST API) for a very basic need from a static HTML page (no backend)</p>
  
  <p>but without luck

  <p>I do suspect that <code>app</code> identifier isn't supported, it is actually the case ? any workaround for my use case (no backend).</p>
