# setNewHost

## Description

The `setNewHost` method allows you to update the host URL for the `ProgramManager`. This is useful if the API endpoint for your Aleo network changes or if you need to switch between different environments (e.g., staging, production).

### Parameters

### Example 

```javascript
zpassSdk.setNewHost('http://localhost:3030');
```
