Obtaining token to embed report

[Michele_Zanoni]

Hello all,

I write for some clarifications. Following the instructions in the last two videos of the documentation section of this page, I have embedded a report into an html code that I have run and that places a report into a web page. So far so good.

Problem is, I have obtained the token by running the code from the app owns data on this github in debug mode. I realize now (it probably was obvious to more savvy developer, but not to me) that that was likely just a trick. In fact, I have noticed that the token after a while expires and I need to run the software again and obtain a new (different) token.

Am I correct in thinking that the authorization token is not static, i.e. it changes and I will not be able to simply copy paste it into my html code once and be done with it?

Assuming I have to obtain the token dynamically, could you give me a suggestion on where to start? I know little (read nothing) of GET, POST, PUT and so on. I'm trying to reverse engineering what I find scattered on forums and the like. For example I have been using this simple code to embed the report:

// Get models. models contains enums that can be used.
var models = window['powerbi-client'].models;

var embedConfiguration = {
	type: 'report',
	id: '5dac7a4a-4452-46b3-99f6-a25915e0fe55',
	embedUrl: 'https://app.powerbi.com/reportEmbed',
	tokenType: models.TokenType.Aad,
	accessToken: 'e4...rf'
};

var $reportContainer = $('#reportContainer');
var report = powerbi.embed($reportContainer.get(0), embedConfiguration);

What can I use to get the accessToken? Should I expand this html code adding something before it? Should I use the code in the example "App owns data"? But in that case, where shall I put the code I have downloaded from Github?

Take a look at the following:

Refresh token using JavaScript SDK example

Basically you need to set a listener on token expiration, once expired, call the SetAccessToken function to update it.

Michael,

thank you for your answer. Unfortunately we need to take a step back. As the document at the link says, I'd need to implement a function generateEmbedToken() that calls the application Back End. Problem is, I've never written a single line of code in javascript, C# or html, nor do I know how Front End or Back End work or communicate.

I've downloaded the code app owns data at this link, I can try to understand what it does and I would be content with simply changing what I need in order to glue together something that works and embeds a report in a web page that I can later on go and change to my liking, but that's a second step. But the first obstacle is already "how do I turn the code I have downloaded in to a web page?"
