Routing API Developer's Guide

Get Routing Zones

Use the getroutingzones resource to query for supported routing zones. Returned data includes zone indentifiers which may be used further in Routing Zone API, for example as values of the excludeZones parameter of the calculateroute resource. The required parameters for the getroutingzones resource are app_id and app_code. A size of the response may be optimized by specifying query criteria like restricting returned zones only to certain countries or zone types.
