# Add a subject to a curriculum container

POST https://unsw-v6-dev.advance-uac.com/institution-api/institution/catalogue/structures/{structureId}/subjects
Content-Type: application/json

Adds a subject to this container, appended after the subjects already in it.

The subject must already exist in the institution's subject catalogue for the same year.
A code we don't hold is a 400, so a typo can't become a dangling reference. 404 if the
container is unknown, 409 if the subject is already in it.

Optionally assert the owner with `programCode` and `programYear`, or `specialisationCode` and `specialisationYear`. Supply one pair, not both.

## 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)

### Body (application/json)

This endpoint expects an AddSubjectRequest.

- `code` (string, optional) — The subject code, e.g. "MATH1131".
- `year` (integer, optional) — Catalogue year of the subject, e.g. 2026.

## Response

### 201

The subject was added to the container.

- `id` (string, optional)
- `itemType` (string, optional) — Course | Major | Minor | Honours | Specialisation | Research. Only Course can be added through the API; the rest came from the handbook.
- `code` (string, optional)
- `year` (integer, optional)
- `name` (string, optional)
- `uoc` (integer, optional) — Credit points this entry contributes.
- `resolved` (boolean, optional) — False when the code isn't in our catalogue. Only ever the case for entries from the original handbook import, because subjects added through the API must resolve.

## Errors

### 400 Bad Request Error

The subject isn't in the institution's catalogue for that year, or only half an owner pair was supplied.

- `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, or it isn't part of the asserted owner.

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

### 409 Conflict Error

It already exists; use PUT to update it.

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