Refreshing the Report Token

To refresh the embed token in Power BI without reloading the page, you can replace the current token by calling the `setAccessToken` method on the report object in the Web UI. This method will apply the new token without requiring a page reload, keeping the session alive.

Here's how you could modify your `getToken` method to use `setAccessToken`:

1. Modify the `getToken` function: Update it to call `report.setAccessToken(newToken)` when a new token is fetched.

2. Implement `setAccessToken`: After parsing the new token from the response, apply it directly to the existing report instance.

Here's how your modified code could look:

javascript

function getToken() {
$.ajax({
type: "GET",
url: "/embedinfo/getembedinfo",
success: function (data) {
var JSONdata = JSON.parse(data);
var newToken = JSONdata.EmbedToken.Token;
var Expiration = JSONdata.EmbedToken.Expiration;

// Update the existing report with the new token
if (report) {
report.setAccessToken(newToken)
.then(() => {
console.log('Token refreshed successfully');
})
.catch(error => {
console.error('Error setting new token:', error);
});
}

console.log('New Token Expiration:', Expiration);
},
error: function (err) {
console.error('Error fetching token:', err);
}
});
}

// Refresh token every 15 minutes or as required
setInterval(getToken, 900000); // 15 minutes

This approach will ensure that the new token is seamlessly applied to the report without needing to reload the page, maintaining the user's session with minimal interruption. Adjust the interval to refresh the token before the expiration time.
