README

omnisense/omniticket's Billetweb, under any PHP host: an organizer's events with their rates, sessions and places left, the attendees of an event (incrementally, as Billetweb asks), and a ticket's barcode checked at the door. Reading only.

use Omniticket\Billetweb\BilletwebFactory;
use Omniticket\Registry;
use Symfony\Component\HttpClient\HttpClient;

$registry = new Registry([new BilletwebFactory(HttpClient::create())], [
    'box_office' => ['factory' => 'billetweb', 'options' => ['user' => '...', 'key' => '...']],
]);
$registry->checker('box_office')->check('1235', '4475320')->result; // CheckResult::Valid...

Options: user, key (Billetweb's back office, "API": a read-only key, restricted to the events the site shows, is enough), timezone (Europe/Paris: Billetweb's dates carry none), currency (EUR: its prices name none), url.

The API, as read on 2026-10-24

Billetweb's API v1 (https://www.billetweb.fr/bo/api.php, OpenAPI description at https://www.billetweb.fr/api/openapi.json), the key in an HTTP Basic header: GET /api/events (and ?id= for one), /api/event/{id}/avail (places left by event, category, rate and session: -1 is no limit), /api/event/{id}/tickets (rates and prices), /api/event/{id}/attendees (last_update for what changed since, barcode for one ticket, disabled=1 to include refunded and cancelled ones). used: 0 not scanned, 1 scanned, 2 gone out, 3 expired. An event's shop URL is its purchase page and the module Billetweb's own embedding code frames.

Terms: the attendee functions are limited to 10 calls a minute; the API is under fair use and monitored: store the data on your side and read attendees incrementally; abuse, intended or not, can suspend the key. What this package does: event() makes three calls (event, avail, tickets), attendees() one, check() one (a lookup by barcode, not a scan of the whole list); updatedSince maps to last_update; nothing throttles the calls - an application checking at the door at more than 10 tickets a minute keeps the attendee list itself (attendees() then Check::among()). The POST check endpoint, which marks a ticket as scanned, is not used.

No PHP client of Billetweb's API was found to reuse (Billetweb publishes the OpenAPI description only).

Verified, and not

• Verified (the core's harness, PHP 8.4): events, one event whole (rates, sessions, places left, "no limit"), attendees with last_update, checks valid, already used, refunded and unknown, a refused key - against the examples of Billetweb's OpenAPI description, as published; every class loading with the package's requirements alone (BareTest).
• Not verified live: no Billetweb account was used.
