Quick Start

Here is a quick example:

GET /your/api/{param}/call

Client client = new Client();

Request request = new Request();
request.setBaseUri("api.test.com");
request.setMethod(Method.GET);
String param = "param";
request.setEndpoint("/your/api/" + param + "/call");

try {
    Response response = client.api(request);
    System.out.println(response.getStatusCode());
    System.out.println(response.getBody());
    System.out.println(response.getHeaders());
} catch (IOException ex) {
    throw ex;
}

POST /your/api/{param}/call with headers, query parameters and a request body.

request.addHeader("Authorization", "Bearer YOUR_API_KEY");
request.addQueryParam("limit", "100");
request.addQueryParam("offset", "0");
request.setBody("{\"name\": \"My Request Body\"}");
request.setMethod(Method.POST);
String param = "param";
request.setEndpoint("/your/api/" + param + "/call");

try {
    Response response = client.api(request);
    System.out.println(response.getStatusCode());
    System.out.println(response.getBody());
    System.out.println(response.getHeaders());
