xAPI is the Application Programming Interface (API) for Collaboration Endpoint software(Cisco CE and RoomOS), for both on-premise registered video conferencing devices (CUCM, VCS) as well as devices registered to Cisco’s cloud service (Cisco Webex Devices).
This collection gathers commands accessible to an 'Admin' user, and local to the collaboration device.
Which commands are available depends on the product, the back-end (on-premise, cloud), and the user role of the local user (admin, audit, integrator, roomcontrol, user). To get an overview of the commands, check the reference guide for the version of CE or RoomOS you are running. Here is a link to the guide for CE 9.8 and RoomOS as of September 2019: https://www.cisco.com/c/dam/en/us/td/docs/telepresence/endpoint/ce98/collaboration-endpoint-software-api-reference-guide-ce98.pdf
