# POST /internal/api/v2/workspaces is deprecated

Split Admin API deprecated POST /internal/api/v2/workspaces without giving a shutdown date yet.

- API: Split Admin API (api.split.io)
- Kind: Endpoint removal
- Takes effect: no date given yet
- Calls after that day: fail
- Calls it hits: `POST /internal/api/v2/workspaces`
- Source: [Announcement](https://developer.harness.io/feature-management-experimentation/troubleshooting-and-resources/split-to-harness-migration/migrate-from-split-to-harness/api-updates)

## What to use instead

Create projects with the Harness Platform Projects API (apidocs.harness.io/org-project); GET /internal/api/v2/workspaces stays available.

The replacement endpoints are Harness Platform APIs that need a Harness API key, a new credential to create.

## Split Admin API's words

> On your migration date, five Split Admin API endpoints will be disabled and replaced with new endpoints on the Harness platform.
