Abstract

Examples described herein may include a playback device receiving, from a control device, a validation-key that includes an application identifier corresponding to a controller application. The playback device may create a session identifier and transmit the session identifier to the control device. The playback device may receive, from the control device, a playback request comprising the session identifier and a playback command. The playback device may determine that the session identifier is valid and then execute the playback command. A computing system may receive identification information related to a controller application and generate the validation-key based on the controller application meeting at least one quality-control metric. The controller application may receive the validation-key from the computing system.
