Session states - Connector API

State	Description	Allowed actions
`UPLOADING`	Accepting data	ingest, `start-upload`, `delete`
`STARTED`	Data loading is in progress	`terminate`
`DONE`	Data loading finished	`initialize-session` (new session; `delete` returns `409`)

Tracking status

Session status is tracked with:

GET /api/v1/uploading/{upload_uuid}/status

Poll this endpoint while packages are being prepared and after start-upload until the session reaches DONE (or returns to UPLOADING after terminate). Additionally:

an email notification about completed data loading can be enabled (ask support);
status is also visible in data-console.datawiz.io.

`GET /status` fields

Field	Description
`session_status`	Current state
`entities`	Uploaded entities (task-type names)
`upload_tasks_finished`	Previously uploaded packages are fully prepared and ready for data loading
`can_upload_entities`	Ingest allowed
`can_start_upload`	`start-upload` allowed
`can_terminate`	`terminate` allowed

Additional transitions

terminate — stop data loading, return to UPLOADING (more uploads allowed)
delete — remove collected data and session (UPLOADING only); returns 409 if status is DONE or STARTED
