An Azure service that provides geospatial APIs to add maps, spatial analytics, and mobility solutions to apps.
According to the Bing maps terms of use here: https://www.microsoft.com/en-us/maps/product Truck routing is considered a premium service and the premium services are not included with the known user licenses (regular or lite). So you would need to license additional transactions to cover that usage. I recommend reaching out to the Bing Maps licensing team to verify this and to move things forward. If based in North America contact maplic@microsoft.com, if outside of North America contact mapemea@microsoft.com
As for transactions, truck routing generates 3 transactions per request. This is documented here: https://learn.microsoft.com/en-us/bingmaps/getting-started/bing-maps-dev-center-help/understanding-bing-maps-transactions
