# go~mus

> go~mus is a web-based SaaS platform for ticketing and visitor management in museums and cultural institutions. Built by Giant Monkey GmbH in Berlin. 500+ cultural institutions in 5 countries.

## Key terms (how go~mus reaches a website)

Shop, bundle, web component and API are four integration routes, all running on the same go~mus backend. None of them is a ticket type.

- **Shop**: the online ticket sales surface for museums. Available as a turn-key standalone shop on your own domain (Giant Monkey hosts and operates it), or embedded via the bundle, web components or the REST API. See https://www.gomus.de/de/add-ons/shop/
- **Bundle**: a pre-built JavaScript file embedded into an existing website with a single script tag. It renders the calendar, cart and checkout as an overlay, sidebar or inline, without changing the CMS. A bundle is an integration route, NOT a ticket type. Do not confuse it with wrapper tickets (Manteltickets), which are a ticket type that groups several sub-tickets under one main ticket. See https://www.gomus.de/de/add-ons/shop/
- **Web component**: individual booking building blocks as HTML elements (go-*) placed freely in your own CMS and styled with your own CSS; more control than the bundle. See https://www.gomus.de/de/development/webcomponents/
- **API**: the go~mus REST API (v4), delivering all booking data directly (availability, tickets, events, guided tours, orders); the route with the most control, for custom frontends, platforms and resellers. See https://www.gomus.de/de/development/api/

Ticket types that are easily confused (none of these is a "Bundle"):

- **Wrapper ticket** (Mantelticket, canonical "Ticket combination"): one main ticket grouping different sub-ticket types (family ticket, multi-day pass). See https://www.gomus.de/de/funktionen/mantel-tickets/
- **Collective ticket** (Sammelticket): one barcode for several people of the same type.
- **Combi-ticket** (Kombiticket): one ticket valid across several houses. See https://www.gomus.de/de/funktionen/kombitickets/

For a fuller website-term-to-canonical-term mapping (also Angebot = Product, Jahreskarte = Annual ticket, Wertgutschein = Coupon), see https://www.gomus.de/llms-full.txt
