The CORS Header 'Access-Control-Allow-Origin' is missing

Question

I\'m trying to use webUntis\'(docs) API for a school project. For now I\'m just trying to establish any kind of connection to the API.

var result;
const url          


        

Answer 1

Sending Access-Control-Allow-Origin to the server solves nothing. Server has to send Access-Control-Allow-Origin set to * to your browser to allow ajax requests to run.
