Hey Champ
You cant just consume these via your browser/pulling down the content from that URL unless you use that webclient version which I have never looked at other that seeing the page in the documentation, plus these all (including the API endpoints) run on different ports to the Enterprise Manager website
you will need to create a session with the sessionmanager first, then pass the authentication header in your requests
Typical workflow for using the API here (note the urls/ports for the API)
https://helpcenter.veeam.com/docs/backu ... tml?ver=95
You can authenticate easily using process here (essentially posting using a basic http auth header to the session manager endpoint)
https://helpcenter.veeam.com/docs/backu ... tml?ver=95
Once your authenticated you'll see a list of available URLs available under your version/roles etc - use the X-RestSvcSessionID that is returned via sessionmanager post above for future requests passing this as a header to the API
Then you can call (http get) the URLs such as (remember to pass the X-RestSvcSessionID header)
http://<Enterprise-Manager>:9399/api/reports/summary
