Endpoint Overview
An application programming interface (API) is a set of functionalities that a service owner provides so people can use its features and/or build software applications. An API details how a user makes requests and the responses they receive in return.
Please refer to these specific endpoints:
All requests to the API must be made over SSL (https, not http).
We recommend using JSON body format when performing API requests. To do a proper JSON-formatted request, ensure you provide Content-Type: application/json in HTTP request headers. Our API supports UTF-8 for character encoding.
Our API uses the HTTP verbs for each action.
