Introduction
YaaS is a cloud platform that allows everyone to easily develop, extend and sell services and applications. YaaS exposes REST Based API’s with OAuth 2.0 authorization.
SAP Lumira supports consumption of different data sources to create data sets but does not support REST based web services with OAuth 2.0 functionality. YaaS exposes its web services which are REST based. The extension gives the users the option to conveniently access YaaS APIs within SAP Lumira. This extension is built with the version 2 Lumira Data Access Extension SDK.
