You may want\nto plan your route.\n\nThe Routes Preferred API lets you plan a route by specifying\na route objective using the `ComputeCustomRoutes` method.\n\nThe `ComputeCustomRoutes` method can also help with route compliance by letting\nyou minimize the difference between the route selected by the operator and the\nroute driven.\n\nUse both the Routes Preferred API and the\n[Navigation SDK](https://developers.google.com/maps/documentation/navigation-sdk)\nto realize the full benefit of route planning.\n| **Note:** You do not have to use the same cloud project for the Routes Preferred API and the Navigation SDK.\n| **Note:** Unlike `ComputeRoutes` API, `ComputeCustomRoutes` only supports two travel modes, `DRIVE` (or the equivalent `TRAVEL_MODE_UNSPECIFIED`) and `TWO_WHEELER`. This method also does not support `via` intermediate waypoints. If you try to use other travel modes or `via` waypoints, the request fails. For more information about `via` waypoints, see [Routes Preferred API waypoints](/maps/documentation/routes_preferred/reference/rest/Shared.Types/Waypoint).\n\nEnable the ComputeCustomRoutes method\n-------------------------------------\n\nBefore you can use the `ComputeCustomRoutes` method in your code, you must\nenable it. For more information on enabling Routes Preferred API\nmethods, see [Getting Started](/maps/documentation/routes_preferred/get_started).\n| **Important:** Check your quota limits for Routes Preferred API methods. If you need to increase your quota limits, contact support by filing a case on the [Google Maps Platform support page](https://console.cloud.google.com/google/maps-apis/support) in the Google Cloud Console, or by calling the [Google Cloud Support Hotline](/maps/documentation/routes_preferred/support#support_hotline).\n\nUse the ComputeCustomRoutes method\n----------------------------------\n\nThe `ComputeCustomRoutes` method requires that you specify a response\nfield mask in the input. You can provide the response field mask by using\nthe URL parameter `$fields` or `fields`, or by using the HTTP/gRPC header\n`X-Goog-FieldMask`. For more information, see\n[System Parameters](https://cloud.google.com/apis/docs/system-parameters).\n\nThe field mask value is a comma-separated list of field paths. Each field path\nis a dot-separated list of field names that represent the message hierarchy.\nA field name is either the JSON object key, or the protobuf field tag name.\nThe field path starts from the top level response message type,\nand is optionally followed by one or more dots, and then the next level\nof field name. In general, field paths are constructed in the following way: \n\n```\ntopLevelField[.secondLevelField][.thirdLevelField][...]\n```\n\nA special case field mask is a wildcard \"\\*\", which selects all root-level\nfields.\n\nFor more information, see:\n\n- [**gRPC API reference**](/maps/documentation/routes_preferred/reference/rpc/google.maps.routes.v1)\n- [**REST API reference**](/maps/documentation/routes_preferred/reference/rest/v1/TopLevel/computeCustomRoutes)\n\nFor examples of using the `ComputeCustomRoutes` method, see\n[Computing a Custom Route (Beta) Examples](/maps/documentation/routes_preferred/custom_route_examples).\n\nCalculating toll fees\n---------------------\n\nFor information on calculating toll fees, see\n[Calculate toll fees](/maps/documentation/routes_preferred/calculate_toll_fees).\n\nFor examples of calculating toll fees, see\n[Computing a Custom Route Examples](/maps/documentation/routes_preferred/custom_route_examples#toll-fee-examples)."]]
