## 18.5.7.1 About REST Data Source Support for Oracle Cloud SaaS Applications

Learn about REST Data Source support for Oracle Cloud SaaS applications.

Determining the REST Data Source Type

For example, if the Fusion Applications REST API you want to work with contains `RestApi/resources/`, you would create a REST Data Source with a Type of Oracle Cloud Applications (SaaS) REST Service. Consider the following examples: `/hcmRestApi/resources/`,`/fscmRestApi/resources/`, or `/crmRestApi/resources/`.

In contrast, if the URL contains `/api/boss/`, you would create a REST Data Source with a Type of Oracle Cloud Applications (BOSS) REST Service.
