Power BI A.P.I Authentication- Front End Application

[R3NNIE]

I am currently trying to make a call to the power b.i a.p.i so that I can use it for my application and understand how to make api calls to microsoft api's. I have not been able to get a response from the api. I get an unauthorized error, that no access control allow origin header is present on the requested resource. I come from a front-end background where I am used to making API calls using javascript and angular.js. I am not familiar with the microsoft API and how it must be authorized. I have tried to read articles but they go over my head. 

The errors are as follows- 

 Failed to load resource: the server responded with a status of 404 (Not Found)

XMLHttpRequest: cannot load https://api.powerbi.com/v1.0/myorg/dashboards. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://renniesb.github.io' is therefore not allowed access. The response had HTTP status code 404.

    nope

Repository with my project code- https://github.com/Renniesb/sample_dashboard/tree/gh-pages

File with Power B.I API call - https://github.com/Renniesb/sample_dashboard/blob/gh-pages/app/services/powerbi.service.js

expected behavior- Show power bi dashboards in the console to test the communication between the app and the power bi A.P.I

Test site: https://Renniesb.github.io/sample_dashboard. To test I authorize with my credentials. How would I let users of this forum test the behavior. How do I enable their credentials?

List of things I've tried already- 

• Created a reverse proxy using the following website: http://shawnsimondeveloper.com/nodeproxyangular/

• Used the JSONP hack to attempt to get around CORS problem.

• Tested the site both locally and on a webpage on github

Hi @R3NNIE!

Have you find any solution to the problem?
I'm in the same situation with the same error.

Thanks!
