API stands for Application Programming Interface and operates as a digital intermediary which facilitates communications between two applications.
The average person uses 10 individual APIs per day through various applications such as Google Maps and social media apps. These apps wouldn’t be able to function without the API as this allows your phone to talk to the app and exchange information which is then displayed on your phone screen. In this modern digital era, APIs are an important part of everyday life.

LITE API is a REST-inspired API designed to make API client developers write a lot less client-side code. It does so by a heavy use of finite state machines (called Wizards) that encapsulate a lot of business logic therefore eliminating a need for API clients to deal with intensive financial process details. It only uses two HTTP verbs GET and POST for all its methods. Wizard API methods have their own custom naming and custom error processing standards which developers need to learn before utilizing them. It uses simple Bearer Authentication.
REST API is a fully compliant RESTful API based on JSON: API specification. It utilizes oAuth 2.0 authentication mechanism, strictly follows all RESTful standards, such as use of HTTP Error status codes to communicate all related errors, and uses a wider set of HTTP verbs (GET, POST, PUT, DELETE, PATCH) for CRUD operations, etc.
