401 Error with seemingly working access token

d9eman — Tue, 28 Nov 2023 22:04:03 GMT

I am using the following code to get an access token, and the final post request returns a status code of 200 and when I print out the access token it looks good. However as soon as I try to use the access token I get a 401 Unauthroized error. I have been slamming my head against the wall looking everywhere for what I am doing wrong and can't find it, please let me know if you have any tips.

app.get('/spotifylogin', function(req, res) {

let url = AUTHORIZE;

url += "?client_id=" + client_id;

url += "&response_type=code";

url += "&redirect_uri=" + redirect_uri;

url += "&show_dialog=true";

url += "&scope=user-top-read";

res.redirect(url); // Show Spotify's authorization screen

});

app.get('/callback', function(req, res) {

const authConfig = {

headers: {

Authorization: `Basic ${Buffer.from(

`${client_id}:${client_secret}`

).toString('base64')}`,

}

};

axios.post(

'https://accounts.spotify.com/api/token',

'grant_type=client_credentials',

authConfig

).then(data => {

access_token = data.data.access_token;

//refresh_token = data.refresh_token;

//localStorage.setItem('refresh_token',refresh_token);

spotify_linked = true;

res.redirect('/toptracks');

})

.catch(error => {

console.log(error);

})

});

This is the function I am calling with the access token which gives me the 401 error.

async function getProfile(accessToken) {

const response = await fetch('https://api.spotify.com/v1/me', {

headers: {

Authorization: 'Bearer ' + accessToken

}

});

const data = await response.json();

console.log(data);

}

It seems you're using the wrong grant type for the Spotify API authentication. Instead of grant_type=client_credentials, for user authentication, you should use grant_type=authorization_code. This change allows you to exchange the authorization code for an access token and refresh token.
