Robust API + Clear documentation.

Our simple JSON API will have you up and faxing in no time! Also, you can post a URL or a string of HTML and we'll send it just like you'd see it in a webkit browser. Isn't that sweet?

# It can't get any easier!
# Try this in your terminal to send a fax:

curl https://api.phaxio.com/v2/faxes \
   -u 'API_KEY:API_SECRET' \
   -F 'to=A_PHONE_NUMBER' \
   -F 'file=@/path/to/a/supported/file'
use Phaxio\Phaxio;

$phaxio = new Phaxio('YOUR_API_KEY', 'YOUR_API_SECRET');
$phaxio->sendFax(array(
    'to' => 'A_PHONE_NUMBER',
    'file' => fopen('/path/to/a/supported/file', 'rb')
));
var Phaxio = require('phaxio'),
  phaxio = new Phaxio(YOUR_API_KEY, YOUR_API_SECRET),
  callback = function(err,data){console.log(data);};

phaxio.sendFax({
    to: 'aPhoneNumber',
    filename: ['/path/to/a/supported/file']
},callback);
Phaxio.api_key = 'YOUR_API_KEY'
Phaxio.api_secret = 'YOUR_API_SECRET'

Phaxio::Fax.create(
  to: 'A_PHONE_NUMBER',
  file: File.open('/path/to/a/supported/file', 'rb')
)
Phaxio phaxio = new Phaxio("YOUR_API_KEY", "YOUR_API_SECRET");

HashMap<String, Object> faxParams = new HashMap<>();
faxParams.put("to", "A_PHONE_NUMBER");
faxParams.put("file", new File("/path/to/a/supported/file"))
phaxio.fax.create(faxParams);
from phaxio import PhaxioApi

phaxio = PhaxioApi('YOUR_API_KEY', 'YOUR_API_SECRET')

phaxio.Fax.send(
  to='A_PHONE_NUMBER',
  files=open('/path/to/a/supported/file', 'rb')
)
var phaxio = new PhaxioClient("YOUR_API_KEY", "YOUR_API_SECRET");

phaxio.Fax.Create(
  to: "A_PHONE_NUMBER",
  file: new FileInfo("/path/to/a/supported/file")
);
