# Crewli API Contract

Base path: `/api/v1/`

Auth: Bearer token (Sanctum) — token delivered via httpOnly cookie, never in the JSON response body. See `/dev-docs/AUTH_ARCHITECTURE.md` for full details.

## Auth

- `POST /auth/login` — returns user data in JSON body. The Sanctum bearer token is set as an httpOnly cookie via `Set-Cookie` header (not included in response body).
- `POST /auth/logout`
- `GET /auth/me`
- `POST /auth/refresh` — rotates the Sanctum token: revokes current token, creates new one, sets new httpOnly cookie. Returns current user data.
- `POST /auth/forgot-password` — request password reset (public, rate-limited). Body: `{ email, app: "app"|"portal"|"admin" }`. Always returns 200 (no email enumeration).
- `POST /auth/reset-password` — reset password with token (public). Body: `{ token, email, password, password_confirmation }`.

## Account Management (authenticated)

- `POST /me/change-password` — change own password. Body: `{ current_password, password, password_confirmation }`. Revokes other sessions.
- `POST /me/change-email` — request email change (sends verification to new address). Body: `{ new_email, password, app: "app"|"portal"|"admin" }`.
- `POST /verify-email-change` — verify email change token (public). Body: `{ token }`. Revokes all sessions.

## Organisations

- `GET /organisations` — list (super admin)
- `POST /organisations` — create
- `GET /organisations/{org}` — show
- `PUT /organisations/{org}` — update
- `GET /organisations/{org}/members` — members
- `POST /organisations/{org}/invite` — invite user
- `POST /organisations/{org}/members/{user}/change-email` — admin initiates email change for a member (org_admin only). Body: `{ new_email }`.

## Events

- `GET /organisations/{org}/events` — list (top-level only by default)
- `GET /organisations/{org}/events?include_children=true` — include sub-events nested in response
- `GET /organisations/{org}/events?type=festival` — filter by event_type (festival|series|event)
- `POST /organisations/{org}/events` — create (supports `parent_event_id` for sub-events)
- `GET /organisations/{org}/events/{event}` — detail (includes children and parent if loaded)
- `PUT /organisations/{org}/events/{event}` — update (does NOT accept `status` — use transition endpoint)
- `POST /organisations/{org}/events/{event}/transition` — change event status via state machine (see below)
- `GET /organisations/{org}/events/{event}/children` — list sub-events of a festival/series

### Event Status Transitions

`POST /organisations/{org}/events/{event}/transition`

Body: `{ "status": "published" }`

Enforces a state machine: only valid forward (and select backward) transitions are allowed.
Returns 422 with `errors`, `current_status`, `requested_status`, and `allowed_transitions` when the transition is invalid or prerequisites are missing.

**Prerequisites checked:**
- `→ published`: name, start_date, end_date required
- `→ registration_open`: at least one time slot and one section required

**Festival cascade:** Transitioning a festival parent to `showday`, `teardown`, or `closed` automatically cascades to all children in an earlier status.

**EventResource** includes `allowed_transitions` (array of valid next statuses) so the frontend knows which buttons to show.

## Event Stats

- `GET /organisations/{org}/events/{event}/stats` — aggregate dashboard counts for the event

### Response

```json
{
  "data": {
    "persons_total": 142,
    "persons_approved": 98,
    "persons_pending": 31,
    "persons_rejected": 8,
    "persons_other": 5,
    "persons_approved_without_shift": 23,
    "pending_identity_matches": 3,
    "shifts_total": 45,
    "shifts_filled": 38,
    "shifts_understaffed": 7
  }
}
```

## Crowd Types

- `GET /organisations/{org}/crowd-types`
- `POST /organisations/{org}/crowd-types`
- `PUT /organisations/{org}/crowd-types/{type}`
- `DELETE /organisations/{org}/crowd-types/{type}`

## Companies

- `GET /organisations/{org}/companies`
- `POST /organisations/{org}/companies`
- `PUT /organisations/{org}/companies/{company}`
- `DELETE /organisations/{org}/companies/{company}`

## Section Categories

- `GET /organisations/{org}/section-categories` — distinct categories used across the organisation's events (for autocomplete). Returns `{ "data": ["Bar", "Podium", ...] }`

## Festival Sections

- `GET /organisations/{org}/events/{event}/sections`
- `POST /organisations/{org}/events/{event}/sections`
- `PUT /organisations/{org}/events/{event}/sections/{section}`
- `DELETE /organisations/{org}/events/{event}/sections/{section}`
- `POST /organisations/{org}/events/{event}/sections/reorder`

> **Festival context:** `{event}` can be a festival parent or a sub-event.
> On a festival parent, sections are for operational planning (build-up, teardown).
> For sub-events, `GET` automatically includes `cross_event` sections from the parent festival.
> Shifts on cross_event sections must use the **parent festival's event_id** in API calls,
> since the section's `event_id` points to the parent.

### Registration Settings (Festival-level bulk management)

- `GET /organisations/{org}/events/{event}/sections/registration-settings` — returns unique section names across the festival with registration visibility, description, and counts
- `PUT /organisations/{org}/events/{event}/sections/registration-settings` — bulk update registration visibility for a section name across all instances in the festival

#### GET Response

```json
{
  "data": [
    {
      "name": "Hoofdpodium Bar",
      "category": "Bar",
      "icon": "tabler-beer",
      "show_in_registration": true,
      "registration_description": "Tap bier en drankjes voor festivalgangers",
      "section_count": 3,
      "section_ids": ["ulid1", "ulid2", "ulid3"]
    }
  ]
}
```

#### PUT Body

```json
{
  "name": "Hoofdpodium Bar",
  "show_in_registration": true,
  "registration_description": "Tap bier en drankjes voor festivalgangers"
}
```

Returns the full updated registration-settings response. Creates activity log `section.registration_settings_updated`.

Auth: org_admin or event_manager on the event's organisation.

## Time Slots

- `GET /organisations/{org}/events/{event}/time-slots`
- `POST /organisations/{org}/events/{event}/time-slots`
- `PUT /organisations/{org}/events/{event}/time-slots/{timeSlot}`
- `DELETE /organisations/{org}/events/{event}/time-slots/{timeSlot}`

> **Festival context:** `{event}` can be a festival parent or a sub-event.
> Festival-level time slots (operational: build-up, teardown, transitions) are separate
> from sub-event time slots (program-specific).
>
> `GET /organisations/{org}/events/{event}/time-slots` returns only the specified event's own time slots by
> default. For sub-events, pass `?include_parent=true` to also include the parent festival's
> time slots — each time slot is marked with a `source` field (`sub_event` or `festival`)
> and includes `event_name` for display grouping. This parameter has no effect on festivals
> or flat events.
>
> For festivals (events with sub-events), pass `?include_children=true` to include all
> sub-event time slots. Each time slot is marked with `source` (`own` or the sub-event's
> `event_id`) and `event_name`. Used by cross_event section shift dialogs that need access
> to all time slots across the festival. This parameter has no effect on sub-events or
> flat events.
>
> Shifts on sub-event sections may reference parent festival time slots (e.g. for build-up
> shifts). Shifts on cross_event sections may reference any time slot from the festival or
> its sub-events. The `time_slot_id` validation accepts time slots accordingly.

## Shifts

- `GET /organisations/{org}/events/{event}/sections/{section}/shifts`
- `POST /organisations/{org}/events/{event}/sections/{section}/shifts`
- `PUT /organisations/{org}/events/{event}/sections/{section}/shifts/{shift}`

- `POST /organisations/{org}/events/{event}/sections/{section}/shifts/{shift}/assign`
- `POST /organisations/{org}/events/{event}/sections/{section}/shifts/{shift}/claim`

> **Festival context:** When managing shifts on a `cross_event` section, the `{event}`
> in the URL must be the parent festival's ID (matching `section.event_id`), not the
> sub-event's ID.

## Shift Assignments

### Claim Body

`POST /organisations/{org}/events/{event}/sections/{section}/shifts/{shift}/claim`

```json
{ "person_id": "01JXYZ..." }
```

Volunteer claims a shift. Status depends on `festival_section.crew_auto_accepts`:
- `true` → status = `approved`, `auto_approved = true`
- `false` → status = `pending_approval`

Validates: shift must be `open`, person must be `approved`, claiming capacity not full (`slots_open_for_claiming`), no time slot conflict.

### Reject Body

## Identity Matches

### Endpoints

- `GET /organisations/{org}/identity-matches` — list pending matches for the organisation (paginated, 25 per page)
- `GET /organisations/{org}/persons/{person}/identity-match` — show pending match for a specific person
- `POST /organisations/{org}/identity-matches/{match}/confirm` — confirm a match (links `person.user_id`, dismisses other pending matches, syncs tags)
- `POST /organisations/{org}/identity-matches/{match}/dismiss` — dismiss a match (hidden, person stays unlinked, not re-suggested)
- `POST /organisations/{org}/identity-matches/{match}/revert` — revert a confirmed match (unlinks `person.user_id`, status → `reverted`)
- `POST /organisations/{org}/identity-matches/bulk-confirm` — bulk confirm multiple matches
- `POST /organisations/{org}/events/{event}/persons/{person}/manual-link` — manually link a person to a user account (body: `{ "user_id": "ulid" }`)
- `POST /organisations/{org}/events/{event}/persons/{person}/unlink` — unlink a person from their user account

### Match Types (`IdentityMatchMethod`)

| Value        | Description                          | Confidence |
| ------------ | ------------------------------------ | ---------- |
| `email`      | Exact email match within org         | `high`     |
| `name_fuzzy` | Levenshtein fuzzy name match         | `medium` (or `high` if DOB also matches) |
| `manual`     | Organiser-initiated manual link      | `high`     |

### Match Confidence (`IdentityMatchConfidence`)

| Value    | Description                                              |
| -------- | -------------------------------------------------------- |
| `high`   | High certainty — exact email, or fuzzy name + DOB match  |
| `medium` | Moderate certainty — fuzzy name match without DOB        |

### Match Status (`IdentityMatchStatus`)

| Value       | Description                                       |
| ----------- | ------------------------------------------------- |
| `pending`   | Awaiting organiser review                         |
| `confirmed` | Organiser confirmed — `person.user_id` is linked  |
| `dismissed` | Organiser dismissed — not re-suggested            |
| `reverted`  | Previously confirmed, then unlinked               |

### Detection

Matches are detected automatically via `PersonObserver`:
- **On Person create**: if person has no `user_id` and has an email or name, `PersonIdentityService::detectMatches()` runs
- **On Person email update**: if person's email changed and person is unlinked, detection re-runs
- **On user creation**: `PersonIdentityService::detectMatchesForUser()` finds all unlinked persons with matching email

Detection strategies (in priority order):
1. **Exact email** within same organisation → `email` / `high`
2. **Fuzzy name** (Levenshtein distance ≤2 for short names, ≤3 for longer) → `name_fuzzy` / `medium`
3. **Fuzzy name + DOB match** → upgrades to `high` confidence

No silent auto-linking. Every identity link requires explicit confirmation.

### Bulk Confirm

`POST /organisations/{org}/identity-matches/bulk-confirm`

Body: `{ "match_ids": ["ulid1", "ulid2", ...] }` (max 100)

Response: `{ "confirmed": 2, "errors": [{ "match_id": "ulid3", "error": "User already has a person record with this crowd type in this event." }] }`

### PersonResource enrichment

`GET /organisations/{org}/events/{event}/persons` now includes:

```json
{
  "has_user_account": true,
  "user_account": { "id": "ulid", "email": "jan@example.nl", "full_name": "Jan de Vries" },
  "pending_identity_match": {
    "match_id": "ulid",
    "matched_user": { "id": "ulid", "first_name": "Jan", "last_name": "de Vries", "full_name": "Jan de Vries", "email": "jan@example.nl", "date_of_birth": "1990-01-01" },
    "matched_on": "email",
    "matched_on_label": "E-mail match",
    "confidence": "high",
    "confidence_label": "Hoge zekerheid",
    "match_details": { "matched_fields": ["email"], "..." : "..." }
  }
}
```

  "auto_approve": false,
  "max_persons": 50
}
```

### Add Person Body

```json
{
  "person_id": "01JXYZ..."
}
```

**Business rules:**
- `max_persons`: when set, adding a person beyond the limit returns 422
- `auto_approve`: when true, adding a person with status `pending` automatically sets their status to `approved`
- Duplicate person on same list returns 422

## Registration Field Templates (Organisation Settings)

- `GET /organisations/{org}/registration-field-templates` — list active templates (ordered)
- `POST /organisations/{org}/registration-field-templates` — create template
- `PUT /organisations/{org}/registration-field-templates/{template}` — update template
- `DELETE /organisations/{org}/registration-field-templates/{template}` — delete (org-created) or deactivate (system)

> Templates: organisation-level reusable field definitions. System templates
> are seeded on org creation. Org-admins can customize and add their own.

## Registration Form Fields (Event Settings)

- `GET /organisations/{org}/events/{event}/registration-fields` — list all fields (ordered by sort_order)
- `POST /organisations/{org}/events/{event}/registration-fields` — create field (manually or from template)
- `POST /organisations/{org}/events/{event}/registration-fields/from-template` — create field from template
- `PUT /organisations/{org}/events/{event}/registration-fields/{field}` — update field
- `DELETE /organisations/{org}/events/{event}/registration-fields/{field}` — delete field definition (answers preserved)
- `POST /organisations/{org}/events/{event}/registration-fields/reorder` — bulk reorder
- `POST /organisations/{org}/events/{event}/registration-fields/import-from-event` — copy fields from another event

### From-Template Body

```json
{ "template_id": "ulid" }
```

Creates a COPY of the template as an event field. The copy is independent — changes don't propagate back to the template.

### Import Body

```json
{ "source_event_id": "ulid" }
```

Copies all `registration_form_fields` from the source event. Source must belong to the same organisation. Existing fields on the target event are kept.

### Tag Picker Fields

For `tag_picker` fields: the API response includes `available_tags` array (from `person_tags`, filtered by `tag_category` if set) so the frontend knows which tags to render as options.

## Person Field Values

- `GET /organisations/{org}/events/{event}/persons/{person}/field-values` — all answers for a person
- `PUT /organisations/{org}/events/{event}/persons/{person}/field-values` — bulk upsert answers

### Bulk Upsert Body

```json
{
  "values": {
    "field_slug": "value_or_array",
    "shirtmaat": "L",
    "dieetwensen": ["Vegetarisch", "Glutenvrij"],
    "certificaten": ["01JXYZ...", "01JABC..."]
  }
}
```

Replaces all field values for this person in one request. Used by both the registration form and the organiser backend. For `tag_picker` fields: values are arrays of `person_tag_id` ULIDs. If person has a `user_id`, tag sync is triggered automatically.

## Person Section Preferences

- `GET /organisations/{org}/events/{event}/persons/{person}/section-preferences` — list preferences
- `PUT /organisations/{org}/events/{event}/persons/{person}/section-preferences` — replace all preferences

### Replace Body

```json
{
  "preferences": [
    { "festival_section_id": "01JXYZ...", "priority": 1 },
    { "festival_section_id": "01JABC...", "priority": 2 },
    { "festival_section_id": "01JDEF...", "priority": 3 }
  ]
}
```

## Person List Filtering (extended)

Additional filter parameters on `GET /organisations/{org}/events/{event}/persons`:

- `?field[slug]=value` — filter by registration field value (exact match for single-value, `JSON_CONTAINS` for multiselect)
- `?section_preference={section_id}` — filter by section preference (has this section as any priority)
- `?has_preference=true` — only persons who submitted section preferences

_(Extend this contract per module as endpoints are implemented.)_

## Platform Admin

All admin endpoints require `auth:sanctum` + `role:super_admin`. They bypass OrganisationScope and query across all organisations.

Base path: `/api/v1/admin/`

### Admin Organisations

- `GET /admin/organisations` — list all organisations (paginated)
- `GET /admin/organisations/{organisation}` — show with counts and total persons
- `POST /admin/organisations` — not supported (405), use regular endpoint
- `PUT /admin/organisations/{organisation}` — update name, slug, billing_status, settings
- `DELETE /admin/organisations/{organisation}` — soft delete

#### Query Parameters (index)

- `search` — filter by name or slug (partial match)
- `billing_status` — filter by billing status (`trial`, `active`, `suspended`, `cancelled`)

  "billing_status_label": "Active",
  "settings": {},
  "events_count": 5,
  "users_count": 12,
  "total_persons": 342,
  "created_at": "2026-01-15T10:00:00+00:00",

}
```

- `organisation_id` — filter by organisation membership
- `role` — filter by Spatie role name

#### AdminUserResource

```json
{
  "id": "01JXYZ...",
  "first_name": "Jan",
  "last_name": "de Vries",
  "full_name": "Jan de Vries",
  "email": "jan@example.nl",
  "avatar": null,
  "timezone": "Europe/Amsterdam",
  "locale": "nl",
  "email_verified_at": "2026-01-15T10:00:00+00:00",
  "created_at": "2026-01-15T10:00:00+00:00",
  "roles": ["super_admin"],
  "is_super_admin": true,
  "organisations": [
    { "id": "01JXYZ...", "name": "Festival Corp", "slug": "festival-corp", "role": "org_admin" }
  ]
}
```

#### Update Body

```json
{
  "first_name": "Jan",
  "last_name": "de Vries",
  "email": "jan@example.nl",
  "timezone": "Europe/Amsterdam",
  "locale": "nl",
  "roles": ["super_admin"]

```

`roles` accepts platform-level roles only: `super_admin`, `support_agent`. Organisation/event roles are managed via the regular endpoints.

    }
  ],

}
```

### Admin Impersonation

- `POST /admin/impersonate/{user}` — start impersonating a user (requires `role:super_admin`)
- `POST /admin/stop-impersonation` — stop impersonation (requires `auth:sanctum` only, callable by impersonated user)

#### Start Response

```json
{
  "data": {
    "token": "1|abc123...",
    "user": { "...AdminUserResource..." },
    "admin_id": "01JXYZ..."
  }
}
```

#### Stop Response

```json
{
  "data": {
    "user": { "...AdminUserResource (original admin)..." }
  }
}
```

- Cannot impersonate another super_admin (403)
- Impersonation token has name `impersonation-by-{admin_id}`
- Admin ID is cached for 4 hours at key `impersonation:{token_id}`
- Activity log records both start (`admin.impersonation.started`) and stop (`admin.impersonation.stopped`)
