What is REST API? To make it simple, REST API defines a set of functions to which the developers can perform requests and receive responses. The interaction is performed via the HTTP protocol. An advantage of such an approach is the wide usage of HTTP. That is why REST API can be used practically for any programming language.
Common characteristics of Magento REST API resources are as follows: (magentohost is your domain)
- You access the resource by sending an HTTP request to the Magento API server. The server replies with a response that contains either the data you requested, or the status indicator, or even both.
- All resources are located at https://magentohost/api/rest/.
