Methods and systems are provided. One method is providing access to systems of a vehicle from an application. The method includes encoding, by an application, an application programming interface (API) call to the vehicle. The encoding provides for secure communication of the API call to an API subsystem of the vehicle. The API subsystem of the vehicle is configured to decode the encoding. Sending the API call to the vehicle using the encoding. The API call is configured to provide an instruction to obtain information from a subsystem of the vehicle or send an instruction to the subsystem of the vehicle. The sending of the API call to the vehicle is via the application that operates as a third party application that is programmed for communicating with the vehicle via the API call. The method includes receiving, via the third party application, vehicle data sent encoded via the API subsystem of the vehicle responsive to the API call to obtain information. The third party application is configured to decode the vehicle data and present the vehicle data to a user interface of the third party application. The vehicle uses wireless communication for communicating with the third party application.
