I'm using laravel to write a SMS application. So I' am also using the Nexmo API, I followed the tutorial on github,
But, when I try to send it on localhost. I got a curl SSL error:
RequestException in Promise.php line 135: <br/>
cURL error 60: SSL certificate problem: unable to get local issuer certificate
(see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
