===== Register an App =====

[[https://developer.spotify.com/documentation/general/guides/authorization/app-settings/|Register App]]

===== Get your Secrets =====

Get your ClientID, ClientSecret and CallbackURL from the registered App

Create an Authcode, replace <YOURCLIENTID> and <YOURCALLBACKURL> with yours, you also might need to change the scope if you want to gather more info than just your current music. After opening the URL in your browser you will be redirected to an URL with your Code.

<code>
https://accounts.spotify.com/authorize?client_id=<YOURCLIENTID>&response_type=code&redirect_uri=http%3A%2F%2F<YOURCALLBACKURL>%2Fcallback%2F&scope=user-read-currently-playing

Example: 
https://accounts.spotify.com/authorize?client_id=123abcidontcare&response_type=code&redirect_uri=http%3A%2F%2Flocalhost:3000%2Fcallback%2F&scope=user-read-currently-playing

http://localhost:3000/callback/?code=AQCPtOSCKsPt..........YIcyfimgKFeejPg
</code>

Now decode your ClientID and ClientSecret with Base64 (online or via CLI)

<code>
echo "<YOURCLIENTID>:<YOURCLIENTSECRET>" | base64

Example:
echo "blabla:thisissecret" | base64
TH1S1SS0D3C0D3DTH1S1SS0D3C0D3DTH1S1SS0D3C0D3DTH1S1SS0D3C0D3D
</code>

Now get your AccessToken and RefreshToken via CLI

<code>
curl -H "Authorization: Basic <YOURBASE64CODE>" -d grant_type="authorization_code" -d code="<YOURAUTHCODE>" -d redirect_uri="http%3A%2F%2F<YOURCALLBACKURL>%2Fcallback%2F" https://accounts.spotify.com/api/token

Example:
curl -H "Authorization: Basic TH1S1SS0D3C0D3DTH1S1SS0D3C0D3DTH1S1SS0D3C0D3DTH1S1SS0D3C0D3D" -d grant_type="authorization_code" -d code="AQCPtOSCKsPt..........YIcyfimgKFeejPg" -d redirect_uri="http%3A%2F%2Flocalhost:3000%2Fcallback%2F" https://accounts.spotify.com/api/token

{"access_token":"BQCMW.........z8gNg","token_type":"Bearer","expires_in":3600,"refresh_token":"AQDn.........cXK_gU","scope":"user-read-currently-playing"}
</code>

===== Renew your AccessToken =====

If your AccessToken is expired, renew it with your RefreshToken

<code>
curl -H "Authorization: Basic <YOURBASE64CODE>" -d grant_type="refresh_token" -d refresh_token="<YOURREFRESHTOKEN>" -d redirect_uri="http%3A%2F%2F<YOURCALLBACKURL>%2Fcallback%2F" https://accounts.spotify.com/api/token

Example:
curl -H "Authorization: Basic TH1S1SS0D3C0D3DTH1S1SS0D3C0D3DTH1S1SS0D3C0D3DTH1S1SS0D3C0D3D" -d grant_type="refresh_token" -d refresh_token="AQDn.........cXK_gU" -d redirect_uri="http%3A%2F%2Flocalhost:3000%2Fcallback%2F" https://accounts.spotify.com/api/token

{"access_token":"BQC2e.........LDSA","token_type":"Bearer","expires_in":3600,"scope":"user-read-currently-playing"}
</code>

===== Get your current music =====

You can get your music via the following CURL to check your AccessToken

<code>
curl -X "GET" "https://api.spotify.com/v1/me/player/currently-playing" -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer <YOURACCESSTOKEN>"

Example:
curl -X "GET" "https://api.spotify.com/v1/me/player/currently-playing" -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer BQCMW.........z8gNg"
