When using our API, keep the following information in mind:

• When working with events that have the “Clients can pay online or pay when they visit” purchase rule set, you’ll need to set the is_force_pay_later field of your endpoint to true to book an event without payment using the POST method. Otherwise, the “You can not book this class without payment” error message will appear, preventing you from successfully booking the event.
• Property names often include the term “promotion” in the SDK documentation. In the WellnessLiving user interface, this term refers to a Purchase Option (a membership, a session pass, or a package).
• In the WellnessLiving SDK, an SID is a string ID used for communicating information in a human-readable format.
