Ecwid is an E-commerce solution, providing shopping carts and services for online stores. Ecwid also provides a RESTful API (only active for paid accounts) that allows developers to integrate some of Ecwid's services into other applications or websites. For users or developers who want to create applications for Ecwid but don't want to get a paid account, Ecwid provides a test store id (1003) to pass as a parameter, or contact Ecwid and they will provide access to an API test server.
