# Start Service

> Starts an automation service.

`Unary` · [`Environment Automations`](/docs/api-reference/generated/environment-automation/overview)

Starts an automation service. This call does not block until the service is started.
This call will not error if the service is already running or has been started.

Use this method to:

* Start stopped services
* Resume service operations
* Trigger service initialization

### Examples

* Start service:

  Starts a previously stopped service.

  ```yaml theme={null}
  id: "d2c94c27-3b76-4a42-b88c-95a85e392c68"
  ```

## Endpoint

```text theme={null}
POST /api/gitpod.v1.EnvironmentAutomationService/StartService
```

Send a Bearer token as described in [Authentication](/docs/api-reference#authenticate-requests). If your organization uses a custom management-plane domain, replace `https://app.ona.com` with that domain.
