एचटीटीपी अनुरोध और रिस्पॉन्स के लिए, ComputeRouteMatrix
तरीके का इस्तेमाल किया जा सकता है
या gRPC के साथ काम करने वाली किसी भाषा के साथ मिल सकता है, जिसमें Java और Go शामिल है.

टोल शुल्क का हिसाब लगाना
नीचे दिए गए उदाहरण में
computeRouteMatrix
किसी रास्ते पर अनुमानित टोल की जानकारी
टोल पास इस्तेमाल करने पर चुकाई जाने वाली कीमत.
यह सुविधा, routes.travelAdvisory.tollInfo
फ़ील्ड मास्क के साथ चालू है
अनुरोध में बताई गई है. टोल पास की जानकारी route_modifiers
में दी गई है
फ़ील्ड में डालें. दिखाई गई टोल की कीमत,
बताया गया है. अगर एक से ज़्यादा पास दिए गए हैं, तो सबसे सस्ता विकल्प
कीमत दिखाई जाती है.
