# What is Atlas API?

Atlas API supports flight shopping, booking, payment, ticketing, and post-booking operations.

Use it to integrate air-travel booking workflows into your product. The documentation covers implementation guidance, endpoint schemas, and operational support.

### What can you build with Atlas API?

Atlas API supports these core workflows:

* Search and price flight offers.
* Create, pay for, and follow flight orders.
* Manage refunds, voids, ancillaries, and booking records.

### How do I start an Atlas API integration?

Start with [Quick Start](/api-document/readme-1/quick-start.md). It leads through sandbox access, development, UAT validation, and production go-live.

Use [Integration Guides](/api-document/readme-1.md) for the complete implementation lifecycle.

### Which Atlas API booking flow should I use?

Choose a path based on your shopping model and booking requirements.

* Use [Standard booking](/api-document/product-guides/booking/booking-flows/standard-booking-flow.md) for the main search-to-order journey.
* Use [Get Offer](/api-document/product-guides/booking/booking-flows/get-offer-flow.md) for known itineraries.
* Use [Fulfilment API](/api-document/product-guides/booking/booking-flows/fulfillment-flow.md) for its offer-pricing path.

See [Booking Overview](/api-document/product-guides/booking/booking-overview.md) before implementing a flow.

### Where are the endpoint specifications?

[API Reference](/api-document/api-reference.md) contains request schemas, response fields, and endpoint samples.

Use [Product Guides](/api-document/product-guides.md) first for workflow choices. Use API Reference for field-level implementation details.

### Where can I get help?

[Support & Reference](/api-document/support-and-reference.md) covers FAQs, error codes, sandbox test data, and operational utilities.

Start with [Troubleshooting & Support](/api-document/support-and-reference/troubleshooting-and-support.md) when an integration needs diagnosis.
