Convert JSON Java Android - MOIP

I'm using the MOIP API to create a client and I can not extract the following return for JSON in JAVA:

{"id":"CUS-K2R4F6N2E9SL","ownId":"77888888888888","fullname":"ASDASDAS FULL","createdAt":"2018-10-09T01:55:42.000-03","birthDate":"1991-10-22","email":"[email protected]","phone":{"countryCode":"55","areaCode":"19","number":"92833408"},"taxDocument":{"type":"CPF","number":"36442797805"},"shippingAddress":{"zipCode":"01234000","street":"Avenida Faria Lima","streetNumber":"500","complement":"21","city":"Campinas","district":"Itaim","state":"SP","country":"BRA"},"_links":{"self":{"href":"https://sandbox.moip.com.br/v2/customers/CUS-K2R4F6N2E9SL"},"hostedAccount":{"redirectHref":"https://hostedaccount-sandbox.moip.com.br?token=2f549afa-2827-4711-8717-abc6212ade87&id=CUS-K2R4F6N2E9SL&mpa=MPA-A887D7315C56"}}}

But if it comes with error return, something of the tip:

{"errors":[{"code":"CUS-008","path":"customer.ownId","description":"O identificador prßprio deve ser único, j¹ existe um customer com o identificador informado"}]}

I can read normally, because the header contains the "errors" and in the return of success it does not have header, tried of all the forms and I do not succeed.

I'm using OKHTTP to send the data.

Here is the code snippet responsible for sending:

//Para envio de notification para Morador
public static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");

OkHttpClient client = new OkHttpClient();

Call post(String url, String json, Callback callback) {
    RequestBody body = RequestBody.create(JSON, json);
    Request request = new Request.Builder()
            .addHeader("Content-Type", "application/json")
            .addHeader("Authorization", "Basic KEY")
            .url(url)
            .post(body)
            .build();
    Call call = client.newCall(request);
    call.enqueue(callback);
    return call;

        //TaxDocument
