+## Viewing the Request Body
+
+When debugging or testing, it may be useful to examine the raw request body. In the `examples/example.php` file, after your API call use this code to echo out the statuscode, body and headers:
+
+```php
+echo $response->statusCode();
+echo $response->body();
+echo $response->headers();
+```
