The Multi-Tenant LoadMaster Application Program Interface (API) is an interface designed to allow remote applications to access the Multi-Tenant LoadMaster in a simple and consistent manner. The interface is a REST-like interface. REST (Representational State Transfer) is a style of software architecture for distributed systems and is one of the predominant web service design models.

The implementation of the Multi-Tenant LoadMaster API is based on the LoadMaster API. The infrastructure of these APIs is not fully RESTful compliant. For example, the PUT or DELETE HTTP methods are not supported.
