Paubox NodeJS

This is the official NodeJS wrapper for the Paubox Email API.

The Paubox Email API allows your application to send secure, compliant email via Paubox and track deliveries and opens. The API wrapper allows you to construct and send messages.

Further documentation can be found at docs.paubox.com.

Installation

Using npm:

$ npm install --save paubox-node

Getting Paubox API Credentials

You will need to have a Paubox account. You can sign up here.

Once you have an account, follow the instructions on the Rest API dashboard to verify domain ownership and generate API credentials.

Configuring API Credentials

Include your API credentials in your environment file.

Your "API Username" comes from your unique API endpoint.

Base URL: https://api.paubox.net/v1/<USERNAME>

$ echo "API_KEY='YOUR_API_KEY'" > .env
$ echo "API_USERNAME='YOUR_ENDPOINT_NAME'" >> .env
$ echo ".env" >> .gitignore

Or pass them as parameters when creating emailService

const pbMail = require('paubox-node');
const pauboxConfig = {
  apiUsername: 'your-api-username',
  apiKey: 'your-api-key',
};
const service = pbMail.emailService(pauboxConfig);

Usage

To send email, prepare a Message object and call the sendMessage method of emailService.

Sending messages

"use strict";
require('dotenv').config();
const pbMail = require('paubox-node');
const service = pbMail.emailService();

var options = {
  from: '[email protected]',
  to: ['[email protected]'],
  subject: 'Testing!',
  text_content: 'Hello World!',
  html_content: '<html><head></head><body><h1>Hello World!</h1></body></html>',
}

var message = pbMail.message(options)

service.sendMessage(message)
  .then(response => {
    console.log("Send Message method Response: " + JSON.stringify(response));
  }).catch(error => {
    console.log("Error in Send Message method: " + JSON.stringify(error));
  });

Allowing non-TLS message delivery

If you want to send non-PHI mail that does not need to be HIPAA compliant, you can allow the message delivery to take place even if a TLS connection is unavailable.

This means the message will not be converted into a secure portal message when a nonTLS connection is encountered. To do this, include allowNonTLS: true in the options, as shown below:

"use strict";
require('dotenv').config();
const pbMail = require('paubox-node');
const service = pbMail.emailService();

var options = {
  allowNonTLS: true,
  from: '[email protected]',
  to: ['[email protected]'],
  subject: 'Testing!',
  text_content: 'Hello World!',
  html_content: '<html><head></head><body><h1>Hello World!</h1></body></html>',
}

var message = pbMail.message(options)

Forcing Secure Notifications

Paubox Secure Notifications allow an extra layer of security, especially when coupled with an organization's requirement for message recipients to use 2-factor authentication to read messages (this setting is available to org administrators in the Paubox Admin Panel).

Instead of receiving an email with the message contents, the recipient will receive a notification email that they have a new message in Paubox.

"use strict";
require('dotenv').config();
const pbMail = require('paubox-node');
const service = pbMail.emailService();

var options = {  
  forceSecureNotification: 'true',
  from: '[email protected]',
  to: ['[email protected]'],
  subject: 'Testing!',
  text_content: 'Hello World!',
  html_content: '<html><head></head><body><h1>Hello World!</h1></body></html>',
}

var message = pbMail.message(options)

Adding the List-Unsubscribe Header

The List-Unsubscribe header provides the recipient with the option to easily opt-out of receiving any future communications. A more detailed explaination and usage guide for this header can be found at our docs here.

This header can be used by adding the list_unsubscribe: '<Email Unsubscribe Address>, <Web Unsubscribe URL' and list_unsubscribe_post: 'List-Unsubscribe=One-Click' key-value pairs to the options object as follows:

"use strict";
require('dotenv').config();
const pbMail = require('paubox-node');
const service = pbMail.emailService();

var options = {
  from: '[email protected]',
  to: ['[email protected]'],
  subject: 'Testing!',
  text_content: 'Hello World!',
  html_content: '<html><head></head><body><h1>Hello World!</h1></body></html>',
  list_unsubscribe: '<mailto: [email protected]?subject=unsubscribe>, <http://www.example.com/unsubscribe.html>',
  list_unsubscribe_post: 'List-Unsubscribe=One-Click'
}

var message = pbMail.message(options)


### Adding Attachments and Additional Headers


```javascript
"use strict";
require('dotenv').config();
const pbMail = require('paubox-node');
const service = pbMail.emailService();

var attachmentContent = Buffer.from('Hello! This is the attachment content!').toString('base64')

var options = {
  from: '[email protected]',
  reply_to: '[email protected]',
  to: ['[email protected]'],
  bcc: ['[email protected]'],
  cc: ['[email protected]'],
  subject: 'Testing!',
  text_content: 'Hello World!',
  html_content: '<html><head></head><body><h1>Hello World!</h1></body></html>',
  attachments: [{
    fileName: "HelloWorld.txt",
    contentType: "text/plain",
    content: attachmentContent
  }]
}

var message = pbMail.message(options)

Checking Email Dispositions

The SOURCE_TRACKING_ID of a message is returned in the response of the sendMessage method. To check the status for any email, use its source tracking id and call the getEmailDisposition method of emailService:

"use strict";
require('dotenv').config();
const pbMail = require('paubox-node');
const service = pbMail.emailService();

service.getEmailDisposition("SOURCE_TRACKING_ID")
  .then(function (response) {
      console.log("Get Email Disposition method Response: " + JSON.stringify(response));
  });
