An agent may receive an event from a source calendaring system, wherein the event specifies a person, perhaps including a uniform resource locator, having disparate calendaring system. The disparate calendaring system may use a native event format for coordinating events. The agent may lookup a template to convert the event to a native event. The agent may transmit a message with attributes such as a unique identifier to the disparate calendaring system. If the disparate calendaring system acknowledges the event with a success, the agent may log the occurrence of a success. Agent may transmit additional messages having native events to additional disparate systems.
