With this approach, you first get a code which you need to trade against the access-token.
In this exchange you need to provide your Client-Secret and because of that it's not recommended.
A good thing about this method: You can always refresh your token, without having the user to auth it again.</p> <p>More info: <a href="https://developer.spotify.com/documentation/general/guides/authorization-guide/#authorization-code-flow" target="_blank" rel="noopener noreferrer">here<svg xmlns="http://www.w3.org/2000/svg" aria-hidden="true" x="0px" y="0px" viewBox="0 0 100 100" width="15" height="15" class="icon outbound"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path> <polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg></a></p> <div class="language-csharp extra-class"><pre class="language-csharp"><code><span class="token keyword">static</span> <span class="token keyword">async</span> <span class="token keyword">void</span> <span class="token function">Main</span><span class="token punctuation">(</span><span class="token keyword">string</span><span class="token punctuation">[</span><span class="token punctuation">]</span> args<span class="token punctuation">)</span>
