+= Plugin service proxy
+
+If you need to make HTTP requests to an in-cluster service from your plugin, you can declare a service proxy in its `ConsolePlugin` resource by using the `spec.proxy` array field. The console backend exposes the `/api/proxy/plugin/<plugin-name>/<proxy-alias>/<request-path>++?++<optional-query-parameters>` endpoint to proxy the communication between the plugin and the service. A proxied request uses a _service CA bundle_ by default. The service must use HTTPS.
+
+[NOTE]
+====
+The plugin must use the `consolefetch` API to make requests from its JavaScript code or some requests might fail. For more information, see "Dynamic plugin API".
+====
+
+For each entry, you must specify an endpoint and alias of the proxy under the `endpoint` and `alias` fields. For the Service proxy type, you must set the endpoint `type` field to `Service` and the `service` must include values for the `name`, `namespace`, and `port` fields. For example, `/api/proxy/plugin/helm/helm-charts/releases++?++limit++=++10` is a proxy request path from the `helm` plugin with a `helm-charts` service that lists ten helm releases.

+If the service proxy request does not contain the logged-in user's {product-title} access token, set the authorization field to `None`.
+====
+<3> If the service uses a custom service CA, the `caCertificate` field must contain the certificate bundle.
