Quick Start

Here is a quick example:

GET /your/api/{param}/call

Client client = new Client();

Request request = new Request();
request.baseUri = "api.test.com";
request.method = Method.GET;
String param = "param";
request.endpoint = "/your/api/" + param + "/call";

try {
    Response response = client.api(request);
    System.out.println(response.statusCode);
    System.out.println(response.body);
    System.out.println(response.headers);
} catch (IOException ex) {
    throw ex;
}

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

Map<String,String> requestHeaders = new HashMap<String, String>();
requestHeaders.put("Authorization", "Bearer YOUR_API_KEY");
request.headers = requestHeaders;
Map<String,String> queryParams = new HashMap<String, String>();
queryParams.put("limit", "100");
queryParams.put("offset", "0");
request.queryParams = queryParams;
request.body ="{\"name\": \"My Request Body\"}";
request.method = Method.POST;
String param = "param";
request.endpoint = "/your/api/" + param + "/call";

try {
    Response response = client.api(request);
    System.out.println(response.statusCode);
    System.out.println(response.body);
    System.out.println(response.headers);
} catch (IOException ex) {
    throw ex;
}
