# Create a dataset

Creates a new dataset within the specified data source. A dataset acts as a container for ingested data and can later be populated with rows. Once created, the dataset can be used for reporting, visualizations, and transformations within the platform.

Notes:
  - Requires a valid x-api-key with permission to manage datasets in the target account.
  - Each dataset must belong to an existing data source; it cannot exist independently.
  - The dataset is created empty; data is added afterward through ingestion events.

Endpoint: POST /v1/datasets
