How do I get the location of various vehicles at the same time?

The /devices API is always updated with the latest data reported by any device, simply pass the IMEI like this:

https://SITE_URL/api/devices/IMEI

https://pegasus1.pegasusgateway.com/api/devices/357042062897906

the response can be filtered using the select param by passing any of the top level json keys, such as network, version.  Two of these keys can actually provide us with the latest location data:

In order to get more than one device or vehicle’s response in the same request you can use the /vehicles API, and pass the same select parameter with device:keys

https://site_url/api/vehicles?ids=CSV_VEHICLE_IDS&select=device:KEYS

Example:

https://pegasus1.pegasusgateway.com/api/vehicles?ids=1673,2600&select=device:gpsknit

You can even get the vehicle’s information by adding a space and vehicle
