Code samples

Code samples to get you started quickly with Ruby, Python, PHP and Node.js.
Ruby (using standard library)
This Ruby example creates creates a new PDF job. It reads the API key from the PAPERPLANE_API_KEY environment variable, so make sure you have that configured.
require "uri"
require "net/http"
​
endpoint = URI.parse("https://api.paperplane.app/jobs")
http = Net::HTTP.new(endpoint.host, endpoint.port)
http.use_ssl = true
​
request = Net::HTTP::Post.new(endpoint.request_uri)
request.basic_auth(ENV.fetch("PAPERPLANE_API_KEY"), "")
request.set_form_data(
  "url" => "https://en.wikipedia.org/wiki/Airplane",
  "page_size" => "A4"
)
​
response = http.request(request)
puts response.body
Ruby (using the HTTP gem)
This Ruby example uses the HTTP gem which provides a more convenient API than the standard library packages.
# gem install http
​
require "http"
​
response = HTTP.basic_auth(user: ENV.fetch("PAPERPLANE_API_KEY"), pass: "").post(
  "https://api.paperplane.app/jobs",
  json: { url: "https://en.wikipedia.org/wiki/Airplane", page_size: "A4" }
)
​
puts response.body
Python
This Python example creates creates a new PDF job. It reads the API key from the PAPERPLANE_API_KEY environment variable, so make sure you have that configured.
The requests library is used for making HTTP requests, so you'll need to have that installed.
# pip install requests
​
import os
import requests
​
response = requests.post(
    'https://api.paperplane.app/jobs',
    auth=(os.getenv('PAPERPLANE_API_KEY'), ''),
    data={'url': 'https://en.wikipedia.org/wiki/Airplane', 'page_size': 'A4'}
)
​
print(response.json())
PHP
This example creates creates a new PDF job. It reads the API key from the PAPERPLANE_API_KEY environment variable, so make sure you have that configured.
<?php
​
$curl = curl_init();
​
curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://api.paperplane.app/jobs',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_POST => true,
  CURLOPT_POSTFIELDS => array(
    'url' => 'https://en.wikipedia.org/wiki/Airplane',
    'page_size' => 'A4'
  ),
  CURLOPT_USERNAME => getenv('PAPERPLANE_API_KEY')
));
​
$response = curl_exec($curl);
​
curl_close($curl);
​
echo $response;
​
?>
Node.js
This snippet creates creates a new PDF job. It reads the API key from the PAPERPLANE_API_KEY environment variable, so make sure you have that configured.
This example uses the node-fetch library for making HTTP requests.
// npm install node-fetch
​
const fetch = require("node-fetch");
​
const url = "https://api.paperplane.app/jobs";
​
async function createPdf() {
  const auth = new Buffer(process.env.PAPERPLANE_API_KEY + ":").toString(
    "base64"
  );
  const response = await fetch(url, {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      Authorization: `Basic ${auth}`
    },
    body: JSON.stringify({
      url: "https://en.wikipedia.org/wiki/Airplane",
      page_size: "A4"
    })
  });
  const json = await response.json();
  console.log(json);
};
​
createPdf();
Java
This snippet creates creates a new PDF job. It reads the API key from the PAPERPLANE_API_KEY environment variable, so make sure you have that configured.
This example uses the Apache HttpComponents library for making HTTP requests.

            String authHeader = "Basic " + new String(authEncoded);
            HttpPost request = new HttpPost("https://api.paperplane.app/jobs");
            request.setHeader(HttpHeaders.AUTHORIZATION, authHeader);
​
            // Create form data to specify our URL and set some options.
            List<NameValuePair> params = new ArrayList<NameValuePair>();
            params.add(new BasicNameValuePair("url", "https://en.wikipedia.org/wiki/Airplane"));
            params.add(new BasicNameValuePair("page_size", "A4"));
            request.setEntity(new UrlEncodedFormEntity(params));
​
            // Make the POST request.
            HttpClient httpClient = HttpClientBuilder.create().build();
            HttpResponse response = httpClient.execute(request);
            HttpEntity entity = response.getEntity();
            String body = EntityUtils.toString(entity, "UTF-8");
