What tools are supported by SAP Customer Data Platform to call external REST APIs?

The SAP Customer Data Platform supports the use of the Generic Webservice Provider and Connector Studio to call external REST APIs. The Generic Webservice Provider can call any external REST API endpoints, and when the outbound action is executed, the SAP Customer Data Platform prepares the data and sends it to the configured REST API endpoint. The Connector Studio is recommended for building integrations with REST applications1.
