Hi oflok000,

Based on my research, you may need to use the ADAL.js to get the access_token in pure js code. Here is a similar thread for your reference. :smileyhappy:

Sample Code:

<!DOCTYPE html>

<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title></title>
		
       <script src="https://secure.aadcdn.microsoftonline-p.com/lib/1.0.12/js/adal.min.js"></script>
	   <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
			 <script>
			  window.config  = {
				  instance: 'https://login.microsoftonline.com/',
				  tenant: 'common', //COMMON OR YOUR TENANT ID

				  clientId: '49df1bc7-db68-4fb4-91c0-6d93f770d1a4', //This is your client ID
				  redirectUri: 'https://login.live.com/oauth20_desktop.srf', //This is your redirect URI

				  callback: userSignedIn,
				  popUp: true
			  };
			  
			  var ADAL = new AuthenticationContext(config);

				function signIn() {
				      ADAL.login();
				  }
				
				  function userSignedIn(err, token) {
				      console.log('userSignedIn called');
				      if (!err) {
                				          
                  showWelcomeMessage();
				  
				  ADAL.acquireToken("https://analysis.windows.net/powerbi/api", function (error, token) {

            // Handle ADAL Error
            if (error || !token) {
                printErrorMessage('ADAL Error Occurred: ' + error);
                return;
            }

            // Get TodoList Data
            $.ajax({
                type: "GET",
                url: "https://api.powerbi.com/v1.0/myorg/datasets",
                headers: {
                    'Authorization': 'Bearer ' + token,
                },
            }).done(function (data) {

               
                console.log(data);

                    

                // Update the UI
                $loading.hide();
               

            }).fail(function () {
                printErrorMessage('Error getting todo list data')
            }).always(function () {

                // Register Handlers for Buttons in Data Table
                registerDataClickHandlers();
            });
        });
				      }
				      else {
				          console.error("error: " + err);
				      }
				  }
				  
				  
				  
				  
				  function getDataSets(){
				   
						      
                  var trythis = "Bearer " + token;
    							var request = new XMLHttpRequest();

                  request.open('GET', 'https://api.powerbi.com/v1.0/myorg/datasets');
                  
                  request.setRequestHeader('Authorization', trythis);
                  
                  request.onreadystatechange = function () {
                    if (this.readyState === 4) {
                      console.log('Status:', this.status);
                      console.log('Body:', this.responseText);
                    }
                  };
                  
                  request.send();
				  
				  
				  }
				  
				  
				  
				
				  function showWelcomeMessage() {
				      var user = ADAL.getCachedUser();
				      var divWelcome = document.getElementById('WelcomeMessage');
				      divWelcome.innerHTML = "Welcome " + user.profile.name;
				  }
        </script>

    </head>
    <body>
        
        
			 <button id="SignIn" onclick="signIn()">Sign In</button>
			 <h4 id="WelcomeMessage"></h4>	
             
      
             
             
    </body>
</html>
