<h3>异步通知响应</h3>
<p>当商户系统收到异步通知后,需要以JSON格式返回响应,格式如下:</p>
<pre><code class="language-json">{
errcode:0,
errmsg:&quot;success&quot;,
data:null
} </code></pre>
<ul>
<li>
<p><strong>当JSON格式数据值为此时,表示响应成功。如果出现错误,可以在 msg 字段中返回相应的错误信息。</strong></p>
</li>
<li><strong>若响应未包含 "errmsg": "success" ,平台会每隔 5分钟 重发 1次,共3次 通知,直至收到 "errmsg": "success" 。商户需及时处理并返回正确JSON,确保通知顺利接收,若 3次 重发后仍未成功,可主动联系平台确认。</strong></li>
