+
+Below are the properties for each entry inside `backend.mikrotik`:
+
+#### `id`
+- **Default:** *(empty)*
+- **Description:** A unique identifier for this backend.

+# Backends
+
+WireGuard Portal can manage WireGuard interfaces and peers on different backends. 
+Each backend represents a system where interfaces actually live. 
+You can register multiple backends and choose which one to use per interface. 
+A global default backend determines where newly created interfaces go (unless you explicitly choose another in the UI).
+
+**Supported backends:**
+- **Local** (default): Manages interfaces on the host running WireGuard Portal (Linux WireGuard via wgctrl). Use this when the portal should directly configure wg devices on the same server.
+- **MikroTik** RouterOS (_beta_): Manages interfaces and peers on MikroTik devices via the RouterOS REST API. Use this to control WG interfaces on RouterOS v7+.
+
+How backend selection works:
+- The default backend is configured at `backend.default` (_local_ or the id of a defined MikroTik backend). 
+  New interfaces created in the UI will use this backend by default.
+- Each interface stores its backend. You can select a different backend when creating a new interface.
+
+## Configuring MikroTik backends (RouterOS v7+)
+
+> :warning: The MikroTik backend is currently marked beta. While basic functionality is implemented, some advanced features are not yet implemented or contain bugs. Please test carefully before using in production.
+
+The MikroTik backend uses the [REST API](https://help.mikrotik.com/docs/spaces/ROS/pages/47579162/REST+API) under a base URL ending with /rest. 
+You can register one or more MikroTik devices as backends for a single WireGuard Portal instance.
+
+### Prerequisites on MikroTik:
+- RouterOS v7 with WireGuard support.
+- REST API enabled and reachable over HTTP(S). A typical base URL is https://<router-address>:8729/rest or https://<router-address>/rest depending on your service setup.
+- A dedicated RouterOS user with the following group permissions:
+  - **api** (for logging in via REST API)
+  - **rest-api** (for logging in via REST API)
+  - **read** (to read interface and peer data)
+  - **write** (to create/update interfaces and peers)
+  - **test** (to perform ping checks)
+  - **sensitive** (to read private keys)
+- TLS certificate on the device is recommended. If you use a self-signed certificate during testing, set `api_verify_tls`: _false_ in wg-portal (not recommended for production).
+
+Example WireGuard Portal configuration (config/config.yaml):
+
+```yaml
+backend:
+  # default backend decides where new interfaces are created
+  default: mikrotik-prod
+
+  mikrotik:
+    - id: mikrotik-prod              # unique id, not "local"
+      display_name: RouterOS RB5009  # optional nice name
+      api_url: https://10.10.10.10/rest
+      api_user: wgportal
+      api_password: a-super-secret-password
+      api_verify_tls: true         # set to false only if using self-signed during testing
+      api_timeout: 30s             # maximum request duration
+      concurrency: 5               # limit parallel REST calls to device
+      debug: false                 # verbose logging for this backend
+```
+
+### Known limitations:
+- The MikroTik backend is still in beta. Some features may not work as expected.
+- Not all WireGuard Portal features are supported yet (e.g., no support for interface hooks)

docs/documentation/usage/webhooks.md

@@ -0,0 +1,285 @@
+
+Webhooks allow WireGuard Portal to notify external services about events such as user creation, device changes, or configuration updates. This enables integration with other systems and automation workflows.
+
+When webhooks are configured and a specified event occurs, WireGuard Portal sends an HTTP **POST** request to the configured webhook URL. 
+The payload contains event-specific data in JSON format.
+
+## Configuration
+
+All available configuration options for webhooks can be found in the [configuration overview](../configuration/overview.md#webhook).
+
+A basic webhook configuration looks like this:
+
+```yaml
+webhook:
+  url: https://your-service.example.com/webhook
+```
+
+### Security
+
+Webhooks can be secured by using a shared secret. This secret is included in the `Authorization` header of the webhook request, allowing your service to verify the authenticity of the request.
+You can set the shared secret in the webhook configuration:
+
+```yaml
+webhook:
+  url: https://your-service.example.com/webhook
+  secret: "Basic dXNlcm5hbWU6cGFzc3dvcmQ="
+```
+
+You should also make sure that your webhook endpoint is secured with HTTPS to prevent eavesdropping and tampering.
+
+## Available Events
+
+WireGuard Portal supports various events that can trigger webhooks. The following events are available:
+
+- `create`: Triggered when a new entity is created.
+- `update`: Triggered when an existing entity is updated.
+- `delete`: Triggered when an entity is deleted.
+- `connect`: Triggered when a user connects to the VPN.
+- `disconnect`: Triggered when a user disconnects from the VPN.
+
+The following entity models are supported for webhook events:
+
+- `user`: WireGuard Portal users support creation, update, or deletion events.
+- `peer`: Peers support creation, update, or deletion events. Via the `peer_metric` entity, you can also receive connection status updates.
+- `peer_metric`: Peer metrics support connection status updates, such as when a peer connects or disconnects.
+- `interface`: WireGuard interfaces support creation, update, or deletion events.
+
+## Payload Structure
+
+All webhook events send a JSON payload containing relevant data. The structure of the payload depends on the event type and entity involved.
+A common shell structure for webhook payloads is as follows:
+
+```json
+{
+  "event": "create", // The event type, e.g. "create", "update", "delete", "connect", "disconnect"
+  "entity": "user",  // The entity type, e.g. "user", "peer", "peer_metric", "interface"
+  "identifier": "the-user-identifier", // Unique identifier of the entity, e.g. user ID or peer ID
+  "payload": {
+    // The payload of the event, e.g. a Peer model.
+    // Detailed model descriptions are provided below.
+  }
+}
+```
+
+### Payload Models
+
+All payload models are encoded as JSON objects. Fields with empty values might be omitted in the payload.
