PROCESS_SWITCH_SOURCE

Payload	sink stream name (string) current source stream name (string) intended new source stream name, after switch (string) Current process timestamp (milliseconds) stream process configuration (JSON)
Response	always
Response Action	Overrides the intended new source stream name to the response value. If empty, the source switch is aborted. Aborting a fallback-related source switch will shut down the process, aborting other source switch types will prevent the switch from happening and keep the source attached to the previous source stream.
Stream Specific	true
When	Whenever a stream process is about to switch source stream, for any reason
Argument	null

Response: Whether a response is required or ignored. If always a response is needed to continue, if ignored the response will be ignored.

Response Action: What will happen if the trigger is given a certain response. If the response action is none then the trigger cannot directly interrupt the server flow.

Stream Specific : Whether the trigger applies only to selected streams (or all if none are chosen) or whether it always applies.

When : The timing of when the trigger activates.

Argument: If applicable, when the trigger should activate.

If you're having issues working with the trigger we recommend reading up on the Trigger introduction.
