Basic Authorization

The value for the authorization header consists of the word “Basic”, followed by a space, followed by the Base64-encoded version of the client_id and the client_secret. The client_id and client_secret must be separated by a single colon ”:”. The RFC 4648 version of Base64 is required.

var clientId = "q-QynnbDDXVFJCHUPg58EWHH2n5kCWaWYeJ5lVQNI7A"
var clientSecret = "Mq4E2VFNssr5iA7Z7LAdS82vm59wBog5Q5Hl6J-OsL4"
var base64Encoded = btoa(clientId + ":" + clientSecret)
var authorizationHeaderValue = "Basic " + base64Encoded

console.log(authorizationHeaderValue)
