### Programmatically add metadata

You can programmatically add metadata by creating an `IEnumerable<UmbCheckoutMetaData>()` object

{% code title="Create object example" %}

```csharp
var metaData = new List<UmbCheckoutMetaData>
{
    new()
    {
        Name = "Dictionary Key 1",
        Value = "Dictionary Value 1"
    },
    new()
    {
        Name = "Dictionary Key 2",
        Value = "Dictionary Value 2"
    }
}
```

{% endcode %}
