我试图了解为什么有时在Woocommerce中购买后Webhook似乎启动，而有时却不启动。
我的理解是应该向woocommerce插件webhook中添加custom topic的自定义插件，其中添加了以下代码（我将在下面放置整个代码）
function add_new_webhook_topics( $topics ) {
// New topic array to add to the list, must match hooks being created.
$new_topics = array(
'order.gift_card' => __( 'Order Gift Card', 'woocommerce' ),
);
return array_merge( $topics, $new_topics );
}
add_filter( 'woocommerce_webhook_topics', 'add_new_webhook_topics' );
有两个文件，一个是插件，我所能告诉的是它当前所做的就是将自定义主题添加到webhook下拉选项中，以便我们可以在成功下订单后触发一个webhook。但是有时它会触发webhook，有时甚至不尽人意。我之所以这样说，是因为在将有效载荷发送到礼品卡平台后，应该从Webhook发出电子邮件，然后将礼品卡退回并发送电子邮件。
首先是插件PHP代码。我认为其他排队脚本是计划的功能，但仍不确定。

现在，我无法确定这是否实际上是在向礼品卡平台发送有效载荷，或者网络挂钩是否正在完成所有工作。我很困惑，因为礼品卡平台是在Webhook和此插件中调用的，希望有人可以帮助阐明该插件中发生的事情，而不是根据主题触发Webhook。
这是网络挂钩

现在这是我的问题所在。我不知道邮件的原因（$ to，$ subject，$ message，$ headers）；永远不会发送是因为Webhook无法提交到礼品卡服务器，并且在礼品卡服务器端出现错误，或者是因为此Webhook无法发送电子邮件。或者，如果此webhook从未触发过。
现在可以帮助调试如果此Webhook的邮件功能从未发送过，那么通过将订单状态从处理更改为完成就可以发送它的一半时间。但是，这仅应用于内部，我们确实希望自动发送礼品卡信息，但是我希望有一种方法可以执行自定义操作，以从woocommerce的订购页面重新发送该Webhook。就像一个按钮或说重新发送礼品卡电子邮件的内容。
因此，我想了解的是，在Webhook或插件中，真正的有效负载在哪里提交给了礼品卡服务器？以及为什么当我在woocommerce中更改订单状态时，webhook电子邮件只提交一半时间，然后又提交另一半时间。
这里也有JS脚本，但是我现在不认为它们有任何作用。
check-balance.js
jQuery(document).ready(function($) {
// checks card balance
$('.gi-check-balance').submit(function() {
var gx_card_number = $(this).find('[name=card-number]').val()
