<IntegrationHeader integration={wudIntegration} categories={["Health Monitoring"]} />

The What's Up Docker integration lets Homarr connect to your [WUD](https://github.com/getwud/wud) instance so you can see how many of your watched containers have image updates available directly from your dashboard.

### Widgets & Capabilities

<IntegrationCapabilites items={[{ widget: wudWidget }]} />

### Adding the integration

<AddingIntegration />

:::info URL configuration
Use the root URL of your WUD instance, for example `https://wud.example.com`. Homarr calls the `/api/app` and `/api/containers` endpoints under that URL automatically.
:::

### Secrets

WUD does not require authentication by default. If your instance is protected with [Basic Authentication](https://github.com/getwud/wud/blob/main/docs/configuration/authentications/basic/README.md), you can provide a username and password.

<IntegrationSecrets
  secrets={[
    {
      credentials: [],
      steps: [],
    },
    {
      credentials: ["username", "password"],
      steps: [
        "Open your WUD instance's configuration and configure a WUD_AUTH_BASIC_* user as described in the WUD documentation",
        "Enter that username and password in Homarr — Basic authentication is handled automatically",
      ],
    },
  ]}
