# API Consumer Guide This document describes the public JSON API exposed under `/api`, written for developers implementing a **client** in another application. It is self-contained: no access to this codebase is required to use it. ## Overview A Symfony application exposing a read-mostly JSON API under the `/api` prefix. All `/api/*` requests are stateless and authenticated via OAuth2 Bearer tokens (League OAuth2 Server, JWT access tokens). Responses are `application/json`. HTTPS is enforced on all routes. ## Authentication - Token endpoint: `POST /token` (unauthenticated). - Enabled grants: **client_credentials**, **authorization_code** (PKCE required for public clients), **refresh_token**. Password and implicit grants are disabled. - Access token TTL: **10 minutes** — clients must refresh/re-request frequently. - Available scopes: `email`, `id`, `profile`, `roles`, `api`. Default scope if none requested: `email`. - Each granted scope maps to a role `ROLE_OAUTH2_` (e.g. scope `api` → `ROLE_OAUTH2_API`). - Send the token as `Authorization: Bearer `. Scope required per endpoint: | Scope needed | Endpoints | |---|---| | `api` | everything except the two below | | `profile` | `GET /api/crm-attributes` | | `email` | `GET /api/userinfo` (optional extra scopes `id`, `profile`, `roles` widen the response) | `/api/userinfo` and `/api/crm-attributes` act on the **authenticated end user**, so they require an authorization_code token issued for a user. All other endpoints are machine-to-machine and work with client_credentials. ### Machine-to-machine example ``` POST /token Content-Type: application/x-www-form-urlencoded grant_type=client_credentials&client_id=...&client_secret=...&scope=api ``` ``` GET /api/hotels Authorization: Bearer eyJ0eXAi... ``` ## Error conventions There is no single error envelope; three shapes occur: - `{"message": "..."}` — commonly with 404 / 400. - `{"error": "...", "type": "api_error"}` — upstream failures on some endpoints. **Caution:** on `/api/products` and `/api/travels/{dateId}/{hotelId}/{dateTo}/availability` this shape is returned with HTTP **200**, so clients must check for the presence of an `error` key, not only the status code. - `{"success": false, "message": "..."}` — the write endpoints (contact form, newsletter). Validation failures on endpoints using mapped query strings / payloads (`/api/contingents/*`, `/api/newsletter-subscriptions`) return **400** with Symfony's constraint-violation body. Missing/invalid token yields **401**; insufficient scope yields **403**. The HTTP methods listed below are the intended ones. Several read routes do not restrict methods server-side; clients should still use `GET` for them. --- ## Endpoints ### Reference data (BusProNet master data) #### `GET /api/hotels` — scope `api` List of hotels. Array of objects: `id` (int), `code` (string), `name`, `city`, `street`, `phone`, `country`. #### `GET /api/hotels/{id}` — scope `api` Single hotel by numeric id, same field set as the list. `404 {"message":"Not found"}` if unknown. #### `GET /api/countries` — scope `api` Array of `{id, name, token, nationality}`. #### `GET /api/products` — scope `api` Product master data from the upstream BusProNet system, cached server-side for 1 hour. On upstream failure returns `{"error": "...", "type": "api_error"}` **with status 200**. #### `GET /api/last-update` — scope `api` Timestamp of the last upstream data export: `{"timestamp": "YYYY-MM-DD HH:MM:SS"}`. Note: if no export marker file exists the current implementation errors (500) rather than returning null — treat a non-JSON/500 response as "unknown". --- ### Pickups (bus boarding points) #### `GET /api/pickups` — scope `api` Array of `{id, code, city, postalCode, street}`. #### `GET /api/pickups/{id}` — scope `api` Single pickup by numeric id, same fields as the list. #### `GET /api/pickups-planning/{travelCode}` — scope `api` Planned outbound (HIN) boarding stops for one travel code. Returns an array, chronologically sorted: ```json [{"city": "...", "location": "...", "datetime": "YYYY-MM-DD HH:MM", "busNumber": "..."}] ``` `404 {"error":"Planning data not available"}` if no planning has been uploaded yet, `404 {"error":"Travel code not found"}` for an unknown code, `500 {"error":"Failed to read planning data"}` on storage errors. #### `POST /api/pickups-planning` — scope `api` Bulk-replaces the planning dataset. Body: a JSON **array** of raw planning rows using the upstream German keys: ```json [ { "PlanungsArt": "HIN", "Reisecode": "ABC123", "Zustieg/Ausstieg Ort": "Köln", "Zustieg/Ausstieg Strasse": "Hauptbahnhof", "Zeit": "24.12.2026 07:30", "BusNummer": "1" } ] ``` Rows without `PlanungsArt === "HIN"` or without `Reisecode` are dropped; duplicates (same city + location + datetime + bus) are de-duplicated; results are grouped by `Reisecode` and sorted by time. Response `{"status":"ok"}` (200). `400 {"error":"Invalid JSON payload"}`, `500 {"error":"Failed to write pickups planning data"}`. This is a full overwrite, not a merge. --- ### Travels #### `GET /api/travels` — scope `api` Index/mapping of all known travel dates. Object keyed by numeric travel id, each value `{id, code, label, dateFrom, dateTo, hotels: [...]}`. #### `GET /api/travels/{dateId}/{hotelId}` — scope `api` Single travel by **numeric** ids (`hotelId` optional). Route matches only when both segments are digits. #### `GET /api/travels/{dateCode}/{hotelCode}` — scope `api` Same, addressed by **string** codes (`hotelCode` optional). The date code is sanitized (separators stripped) before lookup. `404 {"message":"Not found"}` if the date code is unknown, `404 {"message":"Travel not found"}` if no data exists. Both variants accept optional query parameters: - `source=local` — force the local XML/snapshot data. - `source=remote` — force a live upstream call. - `prefer_remote=1` — used only when `source` is absent; prefers upstream with local fallback. Response fields: `id`, `code`, `productCode`, `productId`, `label`, `hotelId`, `hotel` (hotel object), `dateFrom`, `dateTo`, `type`, `status`, `allowedBookingStatus[]`, `priceFrom`, `selectionGroups[]`, `additionalServices[]`, `transportationServices[]`, `pickups[]`, `dropOffs[]`, `rooms[]`, `guide`, `insurances[]`. #### `GET /api/travels/{dateId}/{hotelId}/{dateTo}/availability` — scope `api` Live hotel availability from the upstream system. `dateTo` must be `Y-m-d`. On upstream failure returns `{"error":"...","type":"api_error"}` **with status 200**. --- ### Contingents & accommodation prices #### `GET /api/contingents/prices?hotelCode=…&year=…` — scope `api` Price timeline for one accommodation and calendar year, collapsed into contiguous segments (adjacent days with the same effective price are merged into one row). The timeline never starts before today; if the requested year is entirely in the past the response is `[]`. - `hotelCode`: required, max 16 chars, `[A-Za-z0-9_-]+` (matches the accommodation's calendar code). - `year`: required int, 1000–9999. Each row: ```json { "dateFrom": "2026-06-01", "dateTo": "2026-06-14", "season": "high|low|...|null", "includedPax": 2, "pricePerNight": 89.5, "priceAdditionalPerson": 25.0, "defaultPricePerNight": 99.0, "defaultPriceAdditionalPerson": 30.0, "currency": "EUR", "type": "discount|null" } ``` Prices are **decimal major units** (converted from integer minor units server-side). `default*` fields are non-null only when the winning price is a discount, and then carry the undiscounted price. `400 {"error":"Hotel not found for hotelCode."}` for an unknown code; `400` with violations for invalid parameters. #### `GET /api/contingents/calendar?hotelCode=…&dateFrom=…&dateTo=…` — scope `api` Per-day availability enriched with prices. Both dates are `Y-m-d` and **inclusive** (`dateTo` is the last night, not the checkout day); the range may not exceed 366 days and `dateTo` must not precede `dateFrom`. Upstream contingent data is cached 1 hour per (hotelCode, dateFrom, dateTo). Each entry: ```json { "date": "2026-06-01", "status": "Free|Blocked|...", "type": "discount|null", "pricePerNight": 89.5, "defaultPricePerNight": 99.0, "priceAdditionalPerson": 25.0, "defaultPriceAdditionalPerson": 30.0, "currency": "EUR", "includedPax": 2, "minNights": 2 } ``` Important rule: **a day with no maintained price is forced to `Blocked`** regardless of what the upstream contingent says. Price fields may be `null` in that case. Errors: `400 {"error":"Hotel not found for hotelCode."}`, `502 {"error":"Failed to fetch contingent data."}` when the upstream contingent service fails, `400` with violations for invalid parameters. --- ### Accommodation bookings (group bookings) #### `GET /api/accommodation-bookings/{uuid}` — scope `api` Single booking by UUID. `404 {"message":"Not found"}` if unknown. ```json { "uuid": "...", "status": "...", "type": "...", "dateFrom": "2026-06-01", "dateTo": "2026-06-08", "nights": 7, "paxCount": 40, "minorsCount": 12, "childrenCount": 3, "groupName": "...", "acceptedAt": "2026-05-01T10:00:00+00:00", "personalData": {}, "accommodation": {}, "boardService": {}, "additionalServices": [], "accommodationDiscount": null, "boardServiceDiscount": null, "additionalServicesDiscount": null, "totalPrice": 123456, "pricingCurrency": "EUR", "pricingVersion": 3, "priceBreakdown": {} } ``` `totalPrice` and the `*Discount` fields are integer **minor units** (cents) — unlike the contingent endpoints. `dateFrom`/`dateTo` are `Y-m-d`; `acceptedAt` is a full ISO-8601 datetime and is `null` until accepted. `priceBreakdown` is a computed nested structure. #### `POST /api/accommodation-bookings/{uuid}/accept` — scope `api` Marks the booking as accepted (server-side side effects: status change, `acceptedAt`, notifications). No request body. Returns the same booking representation as the GET. `404` if unknown. Not idempotent in terms of side effects — call once. --- ### Contact form #### `POST /api/contactform` — scope `api` Creates or matches an address record in the upstream CRM. Request body (all fields optional strings; the upstream system decides what is required): ```json { "lastName": "...", "firstName": "...", "gender": "...", "street": "...", "zipCode": "...", "city": "...", "email": "...", "phone": "..." } ``` - `201` — `{"success": true, "addressId": 123, "personId": 456, "isNewRecord": true}` - `409` — `{"success": false, "message": ""}` (upstream rejected/conflicted) - `400` — `{"success": false, "message": ""}` (upstream call failed) - `422` — malformed payload --- ### Newsletter #### `GET /api/newsletters` — scope `api` The configured newsletter lists as an array of `{id, name, ...}` mapping objects. Use the returned `id` values as `listIds` below. #### `POST /api/newsletter-subscriptions` — scope `api` Request: ```json { "email": "user@example.com", "firstName": "Ada", "lastName": "Lovelace", "listIds": [1, 2] } ``` - `email`: required, strict email validation. - `firstName` / `lastName`: optional, max 255 chars. - `listIds`: required, at least one positive integer; every id must be one of the configured lists. Responses: - `200` — subscription completed, `state: "subscribed"`. - `202` — a double-opt-in confirmation mail was requested, `state: "confirmation_requested"`. - Body in both cases: ```json { "success": true, "email": "user@example.com", "lists": [{"id": 1, "name": "...", "state": "success|pending|already_registered"}], "state": "subscribed|pending_confirmation|confirmation_requested", "confirmationRequested": true } ``` - `400` — unknown or disallowed list ids: `{"success": false, "message": "...", "listIds": [...], "unknownListIds": [...]}`, or validation violations. - `503` — `{"success": false, "email": "...", "listIds": [...], "message": "Newsletter subscription request could not be processed."}` when the newsletter provider is unavailable. Safe to retry. --- ### End-user endpoints (require a user-bound token) #### `GET /api/userinfo` — scope `email` (+ optional `id`, `profile`, `roles`) OIDC-style claims for the authenticated user. The response contains only the claims covered by the granted scopes: - always: `email` - scope `id`: `person_id`, `address_id` - scope `roles`: `roles` (array; the implicit baseline role is stripped, only explicitly assigned roles are exported) - scope `profile`: `profile` object: ```json { "first_name": "...", "last_name": "...", "title": "...", "salutation": "...", "gender": "...", "date_of_birth": "1990-01-01", "nationality": "...", "address": {"street": "...", "postcode": "...", "city": "...", "district": "...", "country": "..."}, "communication": {"email": "...", "mobile": "...", "phone": "...", "newsletter": true}, "hotel_codes": ["..."], "height": null, "weight": null, "shoe_size": null, "remarks": "..." } ``` Note: `profile.communication.email` comes from the CRM address record and is **not necessarily** the login email — a single address can hold several contacts. Use the top-level `email` claim for identity. `400 {"message": "...", "code": "..."}` when the upstream lookup fails or rejects the credentials. #### `GET /api/crm-attributes` — scope `profile` CRM selection attributes/segments for the authenticated user. `400 {"message": "...", "code": "..."}` on upstream failure. --- ## Client implementation notes 1. **Token lifetime is 10 minutes** — implement refresh/re-fetch with a safety margin and retry once on 401. 2. **Check for an `error` key even on 200 responses** for `/api/products` and the travel availability endpoint. 3. **Money units are inconsistent across endpoints**: contingent endpoints return decimal major units; accommodation-booking fields return integer cents. Normalize at the client boundary. 4. **Dates**: `Y-m-d` everywhere except `acceptedAt` (ISO-8601 datetime) and pickup planning (`Y-m-d H:i`). Contingent `dateFrom`/`dateTo` are inclusive night boundaries. 5. **Server-side caching** (1 h on products and the contingent calendar) means upstream changes may not be visible immediately. 6. **Route ambiguity**: `/api/travels/{a}/{b}` resolves to the id-based route when both segments are numeric, otherwise to the code-based route. Non-numeric codes are safe; purely numeric *codes* will hit the id route.
