+# WebHooks
+
+WooCommerce Memberships extends WooCommerce with custom webhooks that are triggered when changes occur to User Memberships or Membership Plan objects.
+
+## User Memberships
+
+Each of the following webhooks will send a corresponding [user membership object](/#the-user-membership) as payload.
+
+Name                          | Description
+----------------------------- | ---------------------------------
+`user_membership.created`     | Triggered when a user membership is created, via any means.
+`user_membership.updated`     | Triggered when a user membership is changed or modified (e.g. status change, update in admin, etc.).
+`user_membership.transferred` | Triggered when a user membership is transferred from a user to another (the user owner of the membership has changed).
+`user_membership.created`     | Triggered when a user membership has been permanently deleted.
+
+## Membership Plans
+
+Each of the following webhooks will send a corresponding [membership plan object](/#the-membership-plan) as payload.
+
+Name                          | Description
+----------------------------- | ---------------------------------
+`membership_plan.created`     | Triggered when a membership plan has been created.
+`membership_plan.updated`     | Triggered when a membership plan has been updated (with one of its properties modified or just saved without data change).
+`membership_plan.deleted`     | Triggered when a membership plan has been moved to the trash (not permanently deleted, but assumed so unless restored).
+`membership_plan.restored`    | Triggered when a membership plan is moved back from the trash (not necessarily as published, could be in draft status or other status).

-Memberships extends [WooCommerce](https://woocommerce.com/) and builds upon the [WordPress REST API](http://v2.wp-api.org/) to handle user memberships and memberships plans data through robust REST API endpoints.
+Since version 1.11.0, Memberships extends [WooCommerce](https://woocommerce.com/) and builds upon the [WordPress REST API](http://v2.wp-api.org/) to handle user memberships and memberships plans data through robust REST API endpoints.
 
 Memberships currently supports v2 of the WooCommerce REST API extension for WordPress, therefore all its endpoints will be added to the `/wc/v2/` route.
