# All Aboard API Documentation

> Tools for selling train tickets and rail passes across Europe via GraphQL API, embeds, and dashboard.

## Getting Started
- [Introduction](https://docs.allaboard.eu/index.md): The All Aboard API provides tools for selling train tickets and rail passes across Europe.
- [Getting Started](https://docs.allaboard.eu/intro/getting-started.md): Before you start, you'll need:
- [API Scopes](https://docs.allaboard.eu/intro/scopes.md): API keys are created and managed from the [Dashboard](https://allaboard.eu/agent).
- [Access Tokens](https://docs.allaboard.eu/intro/access-tokens.md): An **access token** is a credential that reaches one order and nothing else.
- [Key Concepts](https://docs.allaboard.eu/intro/concepts.md): Understanding rail-specific terminology helps you build better integrations and communicate clearly with users.
- [Distance and CO2](https://docs.allaboard.eu/intro/distance-and-co2.md): Every segment in the API carries the distance one passenger travels on it and the CO2 that passenger's trip emits, and this page explains how both figures are made.
- [Booking Flows](https://docs.allaboard.eu/intro/booking-flows.md): This guide shows the complete end-to-end flows for booking tickets and rail passes, from initial search to confirmed purchase.
- [Subscriptions & Streaming](https://docs.allaboard.eu/intro/subscriptions.md): On rare occasions, some API operations can take up to 30 seconds to complete.
- [Query Anything by ID](https://docs.allaboard.eu/intro/node.md): Many objects in the API have unique IDs and implement the [`Node`](/ref/types#Node) interface.

## Booking Tickets
- [Finding Journeys](https://docs.allaboard.eu/tickets/index.md): Before you can book tickets, you need to find available train routes between locations.
- [Getting Offers](https://docs.allaboard.eu/tickets/journey-offer.md): Once you've found a journey, the next step is getting pricing options, what we call **offers**.
- [Booking Tickets](https://docs.allaboard.eu/tickets/book-tickets.md): This guide covers the complete booking process, from creating a booking to receiving confirmed tickets.
- [Travel Cards](https://docs.allaboard.eu/tickets/travel-cards.md): Many travelers hold a card that changes what they pay: a discount card like a BahnCard or a Carte Avantage, an operator's loyalty card, a railcard in the UK, or a rail pass such as Interrail.
- [Corporate Codes](https://docs.allaboard.eu/tickets/corporate-codes.md): A company with a negotiated rate holds a **corporate agreement code** with an operator.
- [Blueprints](https://docs.allaboard.eu/blueprints/index.md): Blueprints are pre-defined journey itineraries that you create once and reuse.

## Booking Rail Passes
- [Finding Rail Passes](https://docs.allaboard.eu/passes/index.md): Rail passes offer flexible travel across Europe.
- [Booking Rail Passes](https://docs.allaboard.eu/passes/booking.md): Booking rail passes follows the same flow as booking tickets: create a booking, add passenger details, then create and finalize an order.

## Orders & Payments
- [Orders](https://docs.allaboard.eu/orders.md): Orders represent confirmed purchases.
- [Payment Methods](https://docs.allaboard.eu/payments/index.md): The All Aboard API supports three ways to pay for orders, each suited to different use cases.
- [Cost Centers](https://docs.allaboard.eu/payments/cost-centers.md): A **cost center** is a named billing configuration on your sales agent.
- [Fees and Reconciliation](https://docs.allaboard.eu/payments/fees.md): Commercial terms vary by client and are agreed separately.

## Manage Orders
- [Refunds](https://docs.allaboard.eu/refunds/index.md): Refunds allow you to return purchased tickets and rail passes to the original payment method.

## Embeds
- [Overview](https://docs.allaboard.eu/embeds/index.md): Embeds provide a simple way to add train content to your website without investing time or effort in complex technologies.
- [Journey List](https://docs.allaboard.eu/embeds/aa-journey-list.md): Building an interface for finding and comparing journeys can be more complex than it first seems.
- [Offer Selection](https://docs.allaboard.eu/embeds/aa-offer-selection.md): The Offer Selection embed is an interface for selecting an offer, place properties and ancillaries for a given [`JourneyOfferSelection`](/ref/types#JourneyOfferSelection).
- [Rail Pass List](https://docs.allaboard.eu/embeds/aa-passbundle-list.md): There is a great variety of rail passes available in the All Aboard API, and to make displaying the options to your customers easier, we offer the embeddable Rail Pass List.
- [Rail Pass Modal](https://docs.allaboard.eu/embeds/aa-passbundle-modal.md): All Aboard offers many different rail passes.
- [Refund Manager](https://docs.allaboard.eu/embeds/aa-refund-manager-modal.md): The Refund Manager embed provides a complete interface for managing refunds on an order.
