This topic describes parameters that are common to all methods in the Groove RESTful API.
|accessToken||string||Required. A valid developer authentication Access Token , used to identify the third-party application using the Groove RESTful API.|
|language||string||Optional. The two-letter standard code identifying the requested language for the response content. If not specified, defaults to the country's primary language.|
|country||string||Optional. The standard two-letter code that identifies the country/region of the user. If not specified, the value defaults to the geolocated country/region of the client's IP address. Responses will be filtered to provide only those that match the user's country/region.|
|contentType||string||Optional. "xml" or "json". Specifies the requested format for response serialization. Default is json. This parameter should be used only when it's not possible to customize standard HTTP headers; otherwise the recommended way to choose serialization format is by using the Accept header.|
|continuationToken||string||Optional. A Continuation Token provided in an earlier service response and optionally passed back to the service to request the continuation of an incomplete list of content.|
Some of the APIs also require a user authentication token in the Authorization header of the request in order to access user-authenticated features such as collection management or full track streaming. See User Authentication for more information on how to create a user authentication header.
