# Releases API

## Releases API

The Releases API handles **booking data** — everything unique to a specific booking.

Your booking system creates a release → GUIBO generates a personalized Trip Link → the traveler gets all travel docs in one place.

#### What you can do

#### How it connects

Releases reference **content data** (guidebooks, libraries) managed in GUIBO or synced via the [Content API](/developers/content-api.md). The Releases API adds the booking-specific layer on top.
