When setting up an integration with the Musement API, we strongly suggest using the <em>latest stable version</em> and specifying that version number in every request.</p>\n<p>In the example below, we are requesting the current stable version, <code class=\"language-text\">3.4.0</code>:</p>\n<div class=\"code-wrapper\">\n        <div class=\"gatsby-code-button-container\"\n             data-toaster-id=\"50404505551683920000\"\n             data-toaster-duration=\"1500\"\n             onClick=\"copyCodeToClipboard(`curl -X GET '{baseUrl}/activities/{activityUuid}' \\\\\n-H 'X-Musement-Application: {applicationValue}' \\\\\n-H 'X-Musement-Version: 3.4.0' \\\\\n-H 'Authorization: Bearer {accessToken}'`, `50404505551683920000`)\"\n        >\n          <div class=\"gatsby-code-button\" title=\"Copy the code snippet\">Copy</div>\n          <div class=\"done-indicator done-indicator-50404505551683920000\">Copied</div>\n        </div>\n        <div class=\"gatsby-highlight\" data-language=\"bash\"><pre class=\"language-bash\"><code class=\"language-bash\"><span class=\"token function\">curl</span> <span class=\"token parameter variable\">-X</span> GET <span class=\"token string\">'{baseUrl}/activities/{activityUuid}'</span> <span class=\"token punctuation\">\\</span>\n<span class=\"token parameter variable\">-H</span> <span class=\"token string\">'X-Musement-Application: {applicationValue}'</span> <span class=\"token punctuation\">\\</span>\n<span class=\"token parameter variable\">-H</span> <span class=\"token string\">'X-Musement-Version: 3.4.0'</span> <span class=\"token punctuation\">\\</span>\n<span class=\"token parameter variable\">-H</span> <span class=\"token string\">'Authorization: Bearer {accessToken}'</span></code></pre></div>\n      </div>\n<p>When a new stable API version is released, the documentation will contain a complete list of changes.
