Problem sending web API to Spotify using Laravel and Guzzle package

I'm trying to communicate with Spotify using web API. So here's the case. In order to retrieve any information from Spotify, first I need to be authorized by Spotify. To do so, I need to send a post request to https://accounts.spotify.com/api/token containing authorization credentials(containing client_id and client_secret), and then in response, I should receive an access token which later I shall use to retrieve any other information. Here's a quick Spotify documentation on how it works :

So the problem here is that I'm doing everything I should but I don't get the token in response.

Here's my code using the Guzzle package in laravel :

And instead of an access token as a response, This HTML output is what I'm receiving from Spotify in return (Without any further information of the problem and any error code):

It is possible that you are misinterpreting this line?

Authorization: Basic <base64 encoded client_id:client_secret>

It looks like you are doing this:

base64_encode($client_id) . ":" . base64_encode($client_secret)

But perhaps they want this:

base64_encode($client_id . ":" . $client_secret);

That is, assuming you have base 64 encoded them at all as this is not actually shown in your code.

Additionally, the documentation states that it wants application/x-www-form-urlencoded encoding.

# Sending Form URL Encoded Requests
https://laravel.com/docs/8.x/http-client#sending-form-url-encoded-requests

To meet this requirement, it looks like you may need to add asForm() to the request.

$response = Http::withHeaders(...)->asForm()->post(...);
