# Attach a draft container tree to a program or specialisation

PUT https://unsw-v6-dev.advance-uac.com/institution-api/institution/catalogue/structures/{structureId}/owner

Attaches a draft container tree to a program or specialisation, stamping the owner onto the
root and every container beneath it.

Only a draft ROOT can be attached. A container with a parent already belongs to its parent's
curriculum, and an already-attached tree is rejected rather than moved, because relocating a
live curriculum wholesale isn't something to do by accident.

Supply exactly one owner: `programCode`+`programYear` or
`specialisationCode`+`specialisationYear`.

## Authentication

- `Authorization` header (bearer token, required) — Paste a Keycloak access token (no "Bearer " prefix)

## Servers

- `https://unsw-v6-dev.advance-uac.com/institution-api` (Dev, default)
- `https://unsw-v6-test.advance-uac.com/institution-api` (Test)

## Request

### Path parameters

- `structureId` (string, required)

### Query parameters

- `programCode` (string, optional)
- `programYear` (integer, optional)
- `specialisationCode` (string, optional)
- `specialisationYear` (integer, optional)

## Response

### 200

The draft and everything beneath it are now part of that curriculum.

- `structureId` (string, optional)
- `containersAttached` (integer, optional) — How many containers were stamped with the new owner: the root plus everything beneath it.

## Errors

### 400 Bad Request Error

No owner supplied, the container isn't a root, or it is LIVE. Set it back to DRAFT first.

- `status` (integer, optional) — Repeats the HTTP status code.
- `error` (string, optional) — What went wrong, in a form safe to show a developer.

### 404 Not Found Error

No such container, program or specialisation.

- `status` (integer, optional) — Repeats the HTTP status code.
- `error` (string, optional) — What went wrong, in a form safe to show a developer.
