# Real-time webhooks Commerce Layer provides a [webhook](https://en.wikipedia.org/wiki/Webhook) mechanism to react to specific events in real-time. To subscribe to one (or more) of those events you need to [create](https://app.gitbook.com/s/RWJeylueWkzLadK710XZ/webhooks/create) the related webhook(s). Each time a subscribed event occurs, we trigger a `POST` request to the endpoint that you specified in the webhook's `callback_url` field. The request contains a JSON payload in the same format that you get when fetching the same resource through the REST API. {% content-ref url="fetching-resources" %} [fetching-resources](https://docs.commercelayer.io/core/fetching-resources) {% endcontent-ref %} For each resource, you can also configure the related resources that should be included in the request body. The relationships will be set as the resource `include` query parameter. {% hint style="info" %} When a `.tagged` event is triggered, the related tag(s) are automatically included in the callback's payload, as relationships of the tagged resource. {% endhint %} {% content-ref url="including-associations" %} [including-associations](https://docs.commercelayer.io/core/including-associations) {% endcontent-ref %} {% hint style="info" %} When a `.destroy` event is triggered the resource payload sent to the webhook endpoint is simplified — since the reference resource is deleted at the time the event is fired, only the destroyed resource's `id` is valorized, while all of the other attributes and included relationships are `null`. {% endhint %} {% content-ref url="deleting-resources" %} [deleting-resources](https://docs.commercelayer.io/core/deleting-resources) {% endcontent-ref %} When you create a new webhook, a **shared secret** is generated. It will be used each time the webhook is fired to sign the payload. The related signature will be stored in the **`X-CommerceLayer-Signature`** header so that you can verify the callback authenticity and consider it reliable. {% content-ref url="callbacks-security" %} [callbacks-security](https://docs.commercelayer.io/core/callbacks-security) {% endcontent-ref %} {% hint style="success" %} If you need to receive real-time notifications for any changes to the resources exposed by our platform, consider also to leverage our SSE-based [event stream hub](https://docs.commercelayer.io/core/event-stream-hub). {% endhint %} ## Supported events You can find here

topic of the the event the triggered the request to the callback URL is also stored in the **`X-CommerceLayer-Topic`** [header](https://docs.commercelayer.io/core/external-resources#request-headers) of the request. {% endhint %} ### Webhooks and imports During [imports](https://docs.commercelayer.io/core/importing-resources) all of the real-time webhooks are **disabled** with the exception of some of the ones related to order status change events, namely: * `orders.place` * `orders.approve` * `orders.cancel` * `orders.authorize` * `orders.void` * `orders.pay` * `orders.refund` * `orders.start_fulfilling` * `orders.cancel_fulfilling` * `orders.fulfill` {% hint style="warning" %} In case you need to leverage all the other real-time events you have to create/update resources via the related API endpoints. {% endhint %} ## Retriggering events Events are automatically triggered at creation time, notifying all listening webhooks. If, for some reason, you want to force the firing of an existing event manually, you can leverage the related trigger attribute on the [event](https://app.gitbook.com/s/RWJeylueWkzLadK710XZ/events#retriggering-events) resource — the event will be immediately triggered, regardless of its uniqueness. ## Responding to webhook callbacks The endpoint listening for webhooks has **5 seconds** to respond with a **`2xx`** (usually `200` ) response code, acknowledging a successful delivery. If the request times out or gets a response with a status code other than `2xx`, it is considered failed. ## Handling webhook failures If a webhook fails (whatever the reason) Commerce Layer tries to fire it again up to **10 times**. After **30 consecutive failures** (retry failures included) no further calls to the related endpoint are made and the webhook has to be reset. {% hint style="info" %} To let you properly handle this scenario and inspect the reasons for the failure, after **5** consecutive non-successful attempts a communication is sent to the owner and all the admins of the organization. {% endhint %}
