How to create prototype for REST api in symfony 2

Question

Hi there for implementing the symfony2 base REST api bundle i have installed the following bundle.

• FosOauth server bundle for Oauth2.0 base authentication
• FosRest bundle for REST api creation.

now can any body suggest me how can i create generalize prototype for all REST API call response. in json format like

{
    "responseType" : "[FAILED|PASSED]",
    "data" : ["RESPECTIVE DATA WILL COME HERE"],
    "errorCode" : "if any ERROR comes we can set those respective code here",
    "errorMessage": "respective error messages either in the string or array"
}

Thanks in advance :)
