# Add a new catalogue subject

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

Creates a subject in the institution's catalogue. `code` and `year` are required and together
identify it.

This never updates. If a subject already exists for that (`code`, `year`) the response is 409,
so use `PUT /{code}/{year}` instead. An `externalIds` value already registered against a different
subject is a 400.

Reference: https://docs-unsw-v6.advance-uac.com/unsw-advance-institution-api/catalogue/add-a-new-catalogue-subject

## 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

### Body (application/json)

This endpoint expects a SubjectCreateRequest.

- `code` (string, optional) — The subject code, e.g. "MATH1131".
- `year` (integer, optional) — Catalogue year, e.g. 2026. The same code in another year is a distinct subject with its own id.
- `name` (string, optional)
- `creditPoints` (integer, optional) — Credit points (UOC) the subject is worth.
- `studyLevel` (string, optional) — e.g. Undergraduate / Postgraduate. A cross-listed subject is one row; use the level it is primarily offered at.
- `fieldOfEducation` (string, optional)
- `facultyName` (string, optional) — The owning faculty's name as your system records it. The matching group on our side is resolved separately, so this is a label, not a link.
- `schoolName` (string, optional)
- `kind` (string, optional) — Whether this row is a specific subject or an unspecified credit block (a placeholder used to grant credit without naming a subject).
- `complexity` (string, optional) — How advanced the subject is. Free text, but use the same vocabulary as the `studyLevel` recorded on applicants' subjects (introductory, intermediate, advanced), because credit matching compares the two and a mismatch fails to match silently rather than erroring.
- `description` (string, optional) — Summary of what the subject covers. Shown in the UI, and intended as input to similarity matching later, so prose is more useful here than keywords.
- `learningOutcomes` (string, optional) — What a student can do on completing the subject. Same purpose as `description`: display now, similarity matching later.
- `discipline` (string, optional) — Discipline code for the subject. Lets a structure group by discipline directly instead of parsing a prefix out of the subject code, which breaks as soon as a code doesn't follow the usual pattern.
- `availability` (string, optional) — When the subject can be studied. Carried into outcome reporting for international students, who need to know which terms are offered.
- `conditions` (string, optional) — Prerequisites, equivalents, exclusions and anything else that affects whether credit can be granted for this subject. Displayed to whoever is assessing an RPL claim, not evaluated automatically.
- `externalIds` (map from string to string, optional) — Your own identifiers for this subject, keyed by system name, e.g. \{"sis": "CRS-1131"}. An id already used for a different subject is rejected.

## Response

### 201

The subject was created.

- `id` (string, optional) — Our stable id for the subject, unchanged by an update.
- `code` (string, optional)
- `year` (integer, optional)
- `status` (string, optional) — created | updated.

## Errors

### 400 Bad Request Error

Missing or invalid fields, or an `externalIds` value already registered against a different subject.

- `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.
