Loyalty Management Business APIs are RESTful APIs that are sometimes available as Apex

REST Reference
You can access Loyalty Management APIs using REST endpoints. These REST APIs follow similar conventions as Connect REST APIs.
Loyalty Management Connect API Interchangeable Request Fields
The Loyalty Management Business API supports interchangeable fields in JSON requests. For some of the request fields, you can use either an ID, number, or name. For example, if you don’t want to store and use Salesforce IDs when accessing Loyalty Management-related data from an external system, simply use names and numbers instead.
