## [What are Webhooks?](https://github.com/woocommerce/woocommerce/blob/trunk/docs/webhooks#what-are-webhooks)
A [Webhook](http://en.wikipedia.org/wiki/Webhook) is an event notification sent to a URL of your choice. Users can configure them to trigger events on one site to invoke behavior on another.
Webhooks are useful for integrating with third-party services and other external API that support them.
## [Webhooks in WooCommerce](https://github.com/woocommerce/woocommerce/blob/trunk/docs/webhooks#webhooks-in-woocommerce)
Webhooks were introduced in WooCommerce 2.2 and can trigger events each time you add, edit or delete orders, products, coupons or customers.
It's also possible to use webhooks with WooCommerce actions, e.g., Create a webhook to be used every time a product is added to the shopping cart, using the action `woocommerce_add_to_cart`.
- **Name**: The **name** is auto-generated as "Webhook created on [date and time of creation]" as a standard to facilitate creation. Change the name to something else.
- **Topic**: Indicate when the webhook should be triggered - **Order Created**, **Product Deleted**, or **Customer Updated**. There are also **Action** and **Custom** options.
- **Action Event**: This option is available when the Topic is a WooCommerce **Action**, such as `woocommerce_add_to_cart` for when customers add products to the shopping cart.
- **Custom Topic**: This option is for **advanced users only**. It's possible to introduce new, customized topics with the help of `woocommerce_webhook_topic_hooks` filter.
- **Secret**: The Secret Key generates a hash of the delivered webhook and is provided in the request headers. This defaults to the current API user's consumer secret, if nothing is entered.
> **Note**: The first time your webhook is saved with the Activated status, it sends a ping to the Delivery URL.
Webhooks are disabled after 5 retries by default if the delivery URL returns an unsuccessful status such as `404` or `5xx`. Successful responses are `2xx`, `301` or `302`.
To increase the number of retries, you can use the `woocommerce_max_webhook_delivery_failures` filter function.
## [Editing and deleting webhooks](https://github.com/woocommerce/woocommerce/blob/trunk/docs/webhooks#editing-and-deleting-webhooks)
Webhooks are listed the same way as posts or products.
1. Find the webhook you wish to alter.
2. Hover over the name, and **Edit** and **Delete permanently** options appear.
3.**Delete**, or make **Edits** and **Save changes**. Bulk deletion is also possible with the dropdown.
