Outbound APIs

An outbound API is a specific type of Application Programming Interface (API) that transfers data from one application to another. In the context of SAP Sustainability Control Tower, an outbound API facilitates the transfer of data from the SAP Sustainability Control Tower database to your client application.

Utilizing an outbound API allows you to access and retrieve information about measures or metrics from the SAP Sustainability Control Tower database. This capability enables the design of customized displays and facilitates the integration of acquired data into your custom systems. SAP Sustainability Control Tower has predefined outbound APIs for various use cases, helping you to efficiently extract and use data in your custom applications.

SAP Sustainability Control Tower and API services are accessible on multiple data centers. To ensure seamless access, you must specify the appropriate datacenter URL when making calls to the service. The relevant datacenter URL can be found within the API specification, available in both JSON and YAML formats. Refer to the table below for the specific URL for metrics and measures.
