Abstract: A network mapping events to workflow instances. One or more event messages are received with an embedded token from one or more event sources associated with an application. A workflow specification is received that specifies a location of the token embedded in the one or more event messages, and the token is extracted from the one or more event messages using the location of the token specified in the workflow specification. The events are then mapped to a workflow instance of the application based on the token the one or more event messages.
