+
+# Basic usage
+
+For every call you need devID and certID that you can obtain here: https://api.bonanza.com/accounts/new
+
+###Unsecure calls
+
+```php
+<?php
+
+use Shoplo\BonanzaApi\Client\BonanzaClient;
+use Shoplo\BonanzaApi\Credentials\Credentials;
+use Shoplo\BonanzaApi\Request\GetBoothItemsRequest;
+
+//Create credentials object using obtained data
+$credentials = new Credentials('devID', 'certID');
+
+//Create bonanza client
+$client = new BonanzaClient($credentials);
+
+//Create request
+$request = new GetBoothItemsRequest();
+$request->page = 1;
+$request->itemsPerPage = 3;
+$request->boothId = 'boothName';
+
+//Make a call and receive GetBoothItemsResponse object
+$response = $client->getBoothItems($request);
+```
+
+###Secure calls
+
+To make secure call, you need to obtain user auth token first.
+To receive it, you need to make fetchToken call:
+
+```php
+<?php
+
+use Shoplo\BonanzaApi\Request\FetchTokenRequest;
+
+//Create request, and provide the callback url
+$request = new FetchTokenRequest();
+$request->validationCompleteURL = 'http://return.to/url';
+
+//Make a call and get the authorization URL
+$response = $client->fetchToken($request);
+
+//You have the auth token here, but it is inactive, so you can save it for example in the session
+$authToken = $response->fetchTokenResponse->authToken;
+
+//Then you redirect user to the page, where he need to log in and confirm the token.
+// After confirmation the user is taken back to the validationCompleteURL.
+header('Location: '.$response->fetchTokenResponse->authenticationURL);
+```
+
+When the access token is signed, you can make a secure call.
+
+```php
+<?php
+
+use Shoplo\BonanzaApi\Client\BonanzaClient;
+use Shoplo\BonanzaApi\Credentials\Credentials;
+use Shoplo\BonanzaApi\Request\GetBoothItemsRequest;
+use Shoplo\BonanzaApi\Type\RequesterCredentialsType;
+
+//Create credentials object using obtained data
+$credentials = new Credentials('devID', 'certID');
+
+//Create bonanza client
+$client = new BonanzaClient($credentials);
+
+//Create requester credentials containing the received token
+$requesterCredentials = new RequesterCredentialsType();
+$requesterCredentials->bonanzleAuthToken = 'authToken';
+
+//Create request and pass the requesterCredentials to authorize the request
+$request = new GetBoothItemsRequest();
+$request->requesterCredentials = $requesterCredentials;
+$request->page = 1;
+$request->itemsPerPage = 3;
+$request->boothId = 'boothName';
+
+//Make a call and receive GetBoothItemsResponse object
+$response = $client->getBoothItems($request);
