The javscript will parse the fragment part of the URI and sends a request to the web server in the background. The web server then notifies your appliciation via event.</p><divclass="mdxCodeBlock_iHAB"><divclass="codeBlockContent_32p_"><buttontype="button"aria-label="Copy code to clipboard"class="copyButton_1BYj">Copy</button><divtabindex="0"class="prism-code language-csharp codeBlock_19pQ"><divclass="codeBlockLines_2n9r"style="color:#bfc7d5;background-color:#292d3e"><divclass="token-line"style="color:#bfc7d5"><spanclass="token plain">private static EmbedIOAuthServer _server;</span></div><divclass="token-line"style="color:#bfc7d5"><spanclass="token plain"style="display:inline-block">
