What Sabre CSL says…
The Content Services for Lodging (CSL) product collection houses APIs to help you find properties, get information about properties, check prices, and much more.
Two types of APIs are currently available through CSL to match the needs of your solution:
Orchestrated APIs: Supports common use cases for both shopping and booking properties across fewer requests.
Granular APIs: Power the Orchestrated APIs. Using granular APIs, integrate content directly into your workflow, allowing for a more customized experience.
