Results Services are a set of APIs used to download different types of data stored by CTC. Although many telematics applications would poll this data in real time using Data Pump, the Data Pump queues have a storage life of just 48 hours and will send each data element only one time. New Data Pump queues are also not capable of sending historic data, which Results Services can provide (assuming that the data is available within the Results Services storage lifetime).
What follows are useful ways to download event data for devices. All APIs covered below require authentication to CTC. Use the login interface to obtain a new authToken any time your request is rejected with an HTTP 401 error.
