### Choose the right path

#### New integration

Start with [Quick Start](/api-document/readme/quick-start.md).

Then move through:

* [Sandbox Access](/api-document/readme/quick-start/making-requests.md)
* [Sandbox Development](/api-document/readme/quick-start/sandbox-development.md)
* [UAT Validation](/api-document/readme/quick-start/uat-submission-guide.md)
* [Production Go-Live](/api-document/readme/quick-start/production-go-live.md)

#### Core booking flow

Use [Booking Overview](/api-document/readme/booking-overview.md) for search, verify, order, payment, and order lookup.

#### Post-booking operations

Use [Post-booking Overview](/api-document/readme/post-booking-overview.md) and [Post-booking Operations](/api-document/readme/post-booking-overview/post-booking-operations.md) for refunds, maintenance, ancillaries, and claims.

#### Special programs

Use [Special Integrations](/api-document/readme/special-integrations.md) only when your business flow requires airline-specific or discounted fare logic.

#### Operational tools

Use [Utility API Overview](/api-document/readme/utility-api-overview.md) for balance, email, export, and ATRIP access.

#### Shared test and reference data

Use [Integration Reference](/api-document/integration-reference.md) for shared values, sandbox test routes, and sandbox test cards.
