## Body (application/json)

| Name | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| id | string | Yes | groupid123 | The ID of the group to launch |
| decisionReason | string | Yes | Your reason for stopping early | The reason for making the decision to update the experiment status |
| removeTargeting | boolean | No | false | Indicates whether to remove targeting from the experiment |
| holdout | integer | No | 10 | Integer percentage of users to hold back when shipping with holdback. Must be an integer between 0 and 50 (inclusive): the launched group size is computed as 100 - holdout * 2, so values above 50 would produce a negative-sized launched group. When set, the experiment remains live with a holdback group so long-term impact can be measured before making a final decision. Requires the ship_experiment_with_holdout gate to be enabled for the project. Constraints: format: int64, min: 0, max: 50 |
