# Define a Custom Split Activity with Multiple Outcomes

You can provide multiple possible outcomes for your custom split activities in Journey Builder. First, define default outcomes in the activity's config.json. The activity's custom javascript then overrides these default outcomes programmatically, or based on user-supplied values.

:::note
Use the `RestDecision` activity type when configuring multiple outcomes.

## Define Default Outcomes

To define default outcomes, include an `outcomes` object in the activity's config.json.

- Each default outcome must contain an `arguments` object that contains a `branchResult` field. Journey Builder expects the custom activity's Execute REST call response to contain the `{ branchResult: value }` object. The `value` matches the branchResult of one of the activity's outcomes.

- Give the custom activity a label in the UI. Include a `label` field in the outcome's `metaData` object. Journey Builder displays the text in this field when users hover over the branch entry point.

:::note
If you don't define a label, it is loaded using the internationalization (i18n) strings from the config.json.

## Sample

```json
"outcomes": [
    {
        "arguments": {
            "branchResult": "buy_item",
            "some argument": "passed from config.json for buy_item"
        }
    },
    {
        "arguments": {
            "branchResult": "sell_item",
            "some argument": "passed from config.json for sell_item"
        }
    },
    {
        "arguments": {
            "branchResult": "hold_item",
            "some argument": "passed from config.json for hold_item"
        },
        "metaData": {
            "label": "MyCustomLabel"
        }
    }
]
```
