REST API: Overview
Documentation for the deprecated SOAP API feature, can be found here.
The MageRewards API allows a remote interface for authorized external sources to access MageRewards data. You can use this to integrate MageRewards with third party applications which are not necessarily using the Magento system.
Magento 1.x uses oAuth 1.0 as the authentication method for API calls.
The oAuth process is explained in detail on Magento's documentation site under REST Authentication.
Similar to Magento's REST API, MageRewards also supports
json responses based on the
Accept request header.
More details are explained on Magento's documentation site under REST Response Formats.
