​
Step 7: Create Draft Version

Save the model to create a draft version. Draft versions can be edited before publishing. API: POST /instances/:instanceId/twu-models Source: Feature Inventory - API Surface (TWU Models API)

​
Step 8: Publish Model

Once the draft is ready, publish it to make it available for use. API: POST /instances/:instanceId/twu-models/:modelId/publish Source: Feature Inventory - API Surface (TWU Models API)

​
Versioning

To make changes to a published model:
  1. Create a new version
  2. Edit the new version
  3. Publish when ready
Old versions remain available and can be archived. API: POST /instances/:instanceId/twu-models/:modelId/versions Source: Feature Inventory - API Surface (TWU Models API)
