# L'Oréal Studio Tracker — External API (v1)

Server-to-server API for creating projects and deliverables from external
systems (e.g. OMG, brief intake forms, integration scripts).

Base URL: `https://optical-dev.oliver.solutions/loreal-prod-tracker/api/v1`

## Auth

Send the shared API key on every request:

```
x-api-key: <API_KEY>
```

The key matches `process.env.API_KEY` on the server. Requests with a
missing or wrong key get `401 Unauthorized`.

Optionally specify which organization the request applies to:

```
x-org-id: <organization-id>
```

If omitted, requests apply to the first organization in the database
(useful in single-org deployments).

## Idempotency

POST endpoints honour `Idempotency-Key`. A retried request with the same
key + same payload returns the cached response without re-executing:

```
idempotency-key: 7f3c8e2a-...-deterministic-uuid
```

The same key with a *different* payload returns `409 Conflict`. Records
expire after 24 hours.

## Endpoints

### `GET /api/v1/projects`

List all projects visible to the caller. Returns the same shape as the
in-app `/api/projects`.

### `POST /api/v1/projects`

Create a project. If `pipelineTemplateId` is omitted, the org's default
pipeline template is auto-applied. Body matches `createProjectSchema`
(see `src/lib/validators/project.ts`).

Required fields:
- `projectCode` (string, unique per org)
- `name` (string)

Recommended fields:
- `omgJobNumber` (string) — enables Box-folder matching downstream
- `clientTeamId` (string) — drives team visibility
- `requestorUserId` (string) — project owner
- `priority` (`LOW` | `MEDIUM` | `HIGH` | `URGENT`)
- `status` (`PIPELINE` | `ACTIVE` | …)
- `startDate`, `dueDate` (ISO 8601)

Returns `201` + the created project.

```bash
curl -X POST \
  -H "x-api-key: $API_KEY" \
  -H "idempotency-key: $(uuidgen)" \
  -H "content-type: application/json" \
  -d '{
        "projectCode": "API-001",
        "name": "Test integration project",
        "omgJobNumber": "12345",
        "priority": "MEDIUM"
      }' \
  https://optical-dev.oliver.solutions/loreal-prod-tracker/api/v1/projects
```

### `GET /api/v1/projects/{projectId}`

Read-back. Same shape as in-app `/api/projects/{id}` — includes
deliverables, stages, attachments, requestor user, client team.

### `POST /api/v1/projects/{projectId}/deliverables`

Create a deliverable on the given project. Pipeline stages auto-applied
from the project's template (`Deliverable.pipelineTemplate` cascades to
`DeliverableStage` rows). Body matches `createDeliverableSchema`.

Required fields:
- `name` (string)

Common fields:
- `priority`, `dueDate`, `notes`, `externalId` (idempotency for upstream
  webhook callers — distinct from the `Idempotency-Key` header)

Returns `201` + the created deliverable with its stage chain populated.

```bash
curl -X POST \
  -H "x-api-key: $API_KEY" \
  -H "idempotency-key: $(uuidgen)" \
  -H "content-type: application/json" \
  -d '{
        "name": "Hero banner",
        "priority": "HIGH",
        "dueDate": "2026-06-30T12:00:00Z"
      }' \
  https://optical-dev.oliver.solutions/loreal-prod-tracker/api/v1/projects/$PROJECT_ID/deliverables
```

## Error shapes

```json
{ "error": "Project code \"X\" already exists" }
```

All errors return JSON with an `error` string. Status codes:
- `400` — validation error (zod issues joined into one message)
- `401` — missing/wrong API key
- `404` — project not visible (RBAC) or not found
- `409` — Idempotency-Key reused with a different payload
- `500` — server error (check server logs)

## What's NOT here

- Update/delete endpoints — out of scope for v1. External callers create;
  in-app users update.
- Deliverable read-back — `GET /api/v1/projects/{id}` includes
  deliverables in its response. A dedicated deliverable read endpoint can
  be added if external callers need it.
- Bulk endpoints — call POST per project/deliverable.

## Internal notes

- Auth path: `src/middleware.ts` short-circuits API-key requests before
  the session check. `src/lib/api-utils.ts` `getAuthSession()` resolves
  the key into a synthetic ADMIN session for the chosen org.
- Idempotency: `src/lib/api/idempotency.ts` + `IdempotencyRecord` prisma
  model. 24-hour TTL — sweep via cron (see `scripts/`).
- Default pipeline fallback: `src/lib/services/project-service.ts`
  `createProject()` — looks up the org's `PipelineTemplate.isDefault` if
  no `pipelineTemplateId` is supplied.
