Fax That Keeps Up With Healthcare

When fax is an essential part of your business, you need:

Full compliance with industry regulations

Reliable delivery and minimal failures

Fast transmission times

High-quality output

Integrate Rapidly with These Fax API Code Samples

Build smarter apps faster. These Fax API examples in cURL, Ruby, Python, PHP, and Node.js make integration effortless - so you can focus on building, not troubleshooting.

cURL: Rapid Testing and Integration

When fax is an integral part of your business, you can’t afford non-compliance with industry regulations, high failure rates, slow transmission times, and poor output quality.


curl  -X POST 'https://api.documo.com/vl/fax/send'  
-H 'Authorization: Basic YOUR API KEY' 
-H 'content-type: multipart/form-data'  
-F 'recipientFax=12345678900' 
-F 'coverPage=true'  
-F 'recipientName=John Snow'
-F 'subject=Winter is coming'  
-F 'notes=This fax is gonna let you know about the coming winter' 
-F ' =@/home/user/Documents/Winter. pdf'

Ruby: Streamlined App Integration

Ruby developers can embed fax functionality directly into applications or backend scripts, enabling automated document routing, cover page generation, and reliable delivery tracking.


require 'net/http' , require  'uri'
uri  =  URI . parse ( "https : //api.documo.com/v1/fax/send" )  request  =  Net: : HTTP: :
Post . new (uri)  request . content_ type  = "multipart/form-data"
request[ "Authorization" ] = "Basic YOUR API KEY" request . set_form_data( 
"recipientFax" => "12345678900",  "coverPage" => "true", "recipientName" => "John
Snow" , "subject" => "Winter is coming" ,  "notes"  =>  "This fax is gonna let you
know about the coming winter ''  ''  =>  "@/home/user/Documents/Winter . pdf " , 
reg options = {
use ssl: uri.scheme ==  "https", 
response =  http. request  (request), puts response.   read  .  .  /common/templates  _layout

Python: Workflow Automation Made Simple

Python makes it easy to incorporate faxing into broader automated processes, such as routing lab results, authorizations, or claims – reducing manual steps and accelerating document handling.


import  requests
|  url  =  "http://api.documo.com/vl/fax/send',
headers  =  {
'Authorization':'Basic YOUR API KEY',' Content-Type ':' multipart/form-data '  ,
data  =  [
('recipientFax','12345678900') , ' ( ' coverPage ' ,   true ) ,
(  ' recipientName ' ,  'John Snow '  ) ,  ' (  ' subiect ' ,  ' Winter is coming '  ) ,  
( ' notes ' ,  ' This
fax is gonna let you know about the coming winter '
files  =  [
( " ' ,  open ( ' /home/user/Documents/Winter . pdf '  ' rb '  ) ) ,
requests . post ( url,   headers=headers ,  data=data ,  files=files ) ,

PHP: Web App Connectivity

PHP scripts can integrate fax functionality into web forms, portals, or backend systems. Automating fax delivery from your web applications ensures accurate, compliant document handling without additional manual effort.


$ client   =   new   http  Client;
$ request   =   new http  Client  Request;

$body  =  new httpMessageBody;
$body -> addForm(array(  "recipientFax'  =>  '12345678900', 
' recipientName ' => 'John Snow' ,  ' subject '   => ' Winter is coming' , 
'notes' => This fax is gonna let you know about the coming winter ), array(
array(
'name' => ' '
'type' => null,
'file' => ' /home/vlad/Downloads/Winter.pdf ' , 
"data' => null
}
) ) ;
$request -> setRequesturl( ' https://api.documo.com/v1/fax/send ' ) ; $request -
> setRequestMethod (   'POST'   )  ; $request -> setBody ( $body ) ;
$request -> setHeaders ( array (
'Authorization' => ' Basic YOUR API KEY "  ) ) ;
$client->enqueue  (  $request)->send( ) ; $response = $client -> getResponse ( ) ;
echo $response -> getBody ( ) ;

Node.js: Efficient Backend Workflows

Node.js supports sending multiple faxes programmatically as part of backend services or serverless workflows. Use it to streamline document processing and integrate faxing into asynchronous or event-driven applications.


const fs = require ( " fs " ) ;
const request = require ("request")
let fileName ="/home/user/Documents/Winter. pdf"
request ( {
method: ' POST ',  url : ' https :  / / api.documo.com/vl/fax/send', headers: {
Authorization: 'Basic YOUR API KEY', ' content-type ' : ' multipart / form-data '
formData: {
recipientFax: '12345678900', coverPage: true, recipientName: 'John Snow' ,
subject: 'Winter is coming ' ,  notes: ' This fax is gonna let you know about the
coming winter' ;
files:  {
value: fs.createReadStream(fileName),  options: {

filename: fileName contenTType: 'application/pdf"
} , function (  error, response,  body )  { 
'console. log (body);  }  )  ;
