## Multi-Account Usage

If you have multiple UpCloud accounts configured, use account-specific namespaces:

```lua
-- Default account (always works)
app.integrations.upcloud.function_name({...})

-- Explicit default (portable across setups)
app.integrations.upcloud.default.function_name({...})

-- Named accounts
app.integrations.upcloud.production.function_name({...})
app.integrations.upcloud.staging.function_name({...})
```

All functions are identical across accounts — only the credentials differ.
