Get details about a holdout.
### Expanding the holdout response
LaunchDarkly supports the following fields for expanding the "Get holdout" response. By default, these fields are **not** included in the response.
To expand the response, append the `expand` query parameter and add a comma-separated list with any of the following fields:
- `draftIteration` includes the iteration which has not been started yet, if any, for this holdout.
- `previousIterations` includes all iterations prior to the current iteration, for this holdout. By default only the current iteration is included in the response.
- `rel-draftIteration` includes the iteration which has not been started yet, if any, for the experiments related to this holdout.
- `rel-metrics` includes metrics for experiments related to this holdout.
- `rel-previousIterations` includes all iterations prior to the current iteration, for the experiments related to this holdout.
- `rel-secondaryMetrics` includes secondary metrics for experiments related to this holdout.
- `rel-treatments` includes all treatment and parameter details for experiments related to this holdout.
- `secondaryMetrics` includes secondary metrics for this holdout. By default only the primary metric is included in the response.
- `treatments` includes all treatment and parameter details for this holdout. By default treatment data is not included in the response.
For example, `expand=draftIteration,rel-draftIteration` includes the `draftIteration` and `rel-draftIteration` fields in the response. If fields that you request with the `expand` query parameter are empty, they are not included in the response.
