+#### `webhooks`
+OpenAPI have an option to add your application `webhooks`, while this feature isn't supported by `serverless`.
+
+For those the plugin will look for the webhooks under `custom.documentation.webhooks`.
+
+For example
+
+```yaml
+custom:
+  documentation:
+    apiNamespace: MyApi
+    webhooks:
+      WebhookName:
+        post:
+          requestBody:
+            description: |
+              This is a request body description
+          responses:
+            200:
+              description: |
+                This is a expected response description
+```
+
+this will generate the next OpenAPI file
+
+```yaml
+components:
+  schemas:
+    MyApi.Webhooks.WebhookName:
+      type: object
+webhooks:
+  WebhookName:
+    post:
+      requestBody:
+        description: |
+          This is a request body description
+        content:
+          application/json:
+            schema:
+              $ref: '#/components/schemas/MyApi.Webhooks.WebhookName'
+      responses:
+        '200':
+          description: |
+            This is a expected response description
+```
+
+With the next `api.d.ts`:
+
+```typescript
+export namespace MyApi {
+  export namespace Webhooks {
+    export type WebhookName = {
+      id: string,
+      name: string,
+      age: number
+      // ...
+    }
+  }
+}
+```
