Finding the Application & Version#

../../_images/ovas_api_banner_thin.png

To create a Omniverse Kit App stream you have to notify the Application Streaming API of the exact application, version and profile to use. The Application & Profile APIs have methods to query or confirm what applications, versions and profiles exist.

It is important to consider that applications can have multiple versions, and each version/application combination can have multiple profiles.

Never assume that the application, version and profile you want to use, exists. Always confirm using the respective GET methods. Implement user-friendly error-handling if an error status is returned, as trouble-shooting why a stream is not starting can be difficult.
