Notes

• •  At this time, content for begin, end, id, phonetic, route and type are provided by TriMet (Portland) only


• •  Not all original feeds support routes as a query parameter for service messages. In the aggregate, TransiCast / Rasa does not require the routes parameter. As original feeds may not need this parameter, and return service messages for all routes, TransiCast / Rasa directly returns the content of the original feed, including service messages for routes that may not have been requested in the call. It is recommended to include the routes parameter, as some original feeds return error messages when routes are not provided as part of their calls


• •  Original feeds that support calls by route do not require the locIDs parameter
