1 Scope ®
The present document is part of the MirrorLink specification which specifies an interface for enabling remote user
interaction of a mobile device via another device. The present document is written having a vehicle head-unit to interact
with the mobile device in mind, but it will similarly apply for other devices, which provide a colour display, audio
input/output and user input mechanisms.
The MirrorLink API specifies an interface to the MirrorLink Server, which allows any application to either get
information about MirrorLink Server's or Client's properties or to set them to specific values. In addition, the API
specifies callback functions, which are used from the MirrorLink Server to inform the application about any change.

4 Introduction
The MirrorLink API specifies an interface to the MirrorLink Server, which allows any application to either get
information about MirrorLink Server's or Client's properties or to set them to specific values. In addition, the API
specifies callback functions, which are used from the MirrorLink Server to inform the application about any change.
Callback functions shall be implemented from the applications for any evented function.
rd
The MirrorLink APIs define a baseline API that shall be made accessible to 3 party app developers and does in no way
restrict private APIs that can be developed by a MirrorLink Server vendor to satisfy his proprietary needs.
The MirrorLink API specifies the interface in a platform/OS independent manner. Platform specific specification will
describe the detailed platform specific view of the MirrorLink API, which shall be implemented from any MirrorLink
Server device.
The platform specific implementation of the MirrorLink API shall provide method to implement the features specified
in the present document, with at least the values provided in the present document.
A specific API function can be marked as Mandatory or Optional:
• Any Mandatory marked function shall be fully implemented from the MirrorLink Server.
• Any Optional marked function should be fully implemented from the MirrorLink Server. In case the function
is not fully implemented, the MirrorLink Server shall implement an empty shell, which responds with defined
default values and a success flag set to "False" (if available).
The MirrorLink API specifies functions with three types of API functions:
• Get: The function is providing read access to information available on the MirrorLink Server.
• Set: The function is providing write access to information available on the MirrorLink Server.
• Callback: The function is a callback function, invoked from the MirrorLink Server. The implementation of
the callback functionality will be specified in the platform specific specifications.
All three functions may have a Success return value specified. The return value is set to True, if the action has been
successful or the information requested is available. Otherwise the return value is set to False.
Some of the data provided via the MirrorLink API will not be available from MirrorLink 1.0 clients. In such case, the
MirrorLink Server shall provide a default value as specified.
The MirrorLink API uses a set of Data Types, given in Table 1. The platform specific API may use other data types, as
long as the original intend of the MirrorLink API is not compromised. Therefore, the platform specific implementation
of the MirrorLink API may use existing platform APIs are sub-classed versions of them.
