Before adding a webhook, you need to define several settings for it. In the Add new webhook page, you need to choose the webhook type you want to add (product, profile, order, coupon) and to set additional details that may refer to: the action triggered through it (add, update, delete), the mode in which the webhook is sent (simple or multiple). You can also add the URL where the webhook is delivered, the webhook's format, and also it's status (active / inactive). In addition to these settings, you can define the regular expression that will help identify the errors that appear during the request process.
