The REST API can do that, and is easy to learn, but you will need to do the php coding part yourself. It looks like "jsonencode" and "jsondecode" are two libraries that come with PHP that you could use. You will also need to set the header with the API token.

This is how you can get json data

     function curlPost($url,$post_data = NULL) {
       $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        // curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' . 	$this->access_token));
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Authorization: Bearer ' . $this->access_token
        )                                                                       
        );
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        if($post_data != NULL){
            curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($post_data));
        }
        $data = curl_exec($ch);
        $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        return $data;
    }

I m working on REST Api in PHP and I could get all the data from clover api but its taking long time to load the data. How can we reduce the time in order to get the data. Your suggestions would be appreciable.
