Create a new draft dataset version for a dataset group. A draft (version_number = -1) is a mutable staging area where you can add rows before publishing.

​
Authentication

This endpoint requires API key authentication only.

​
Workflow

This endpoint is the first step in the dataset version creation workflow:
  1. Create draft — Use this endpoint to create a draft
  2. Add rows — Use Add Request Log to add request logs as rows
  3. Save — Use Save Draft to publish as a new version

​
Source Dataset

Optionally provide source_dataset_id to copy rows from an existing dataset version. The source dataset must belong to the same dataset group. When a source is provided, rows are copied asynchronously in the background (returns 202).

​
Notes

  • Only one draft can exist per dataset group at a time. Returns 409 if a draft already exists.
  • Without source_dataset_id, an empty draft is created (returns 201).
