# Duplicate a Batch

POST https://api.prolific.com/api/v1/data-collection/batches/{batch_id}/duplicate
Content-Type: application/json

Create a duplicate of an existing AI Task Builder batch. The dataset does not need to be in READY status for duplication. Supports two modes:
- Duplicate with dataset (default): Creates a copy with the same dataset (the dataset is shared between both batches, not duplicated)
- Duplicate without dataset: Creates a copy that requires a new dataset upload (set upload_new_dataset to true)

You can optionally provide a new name for the duplicated batch. If no name is provided, the duplicate will be named "[Original Batch Name] (Copy)".
