Table of Contents


This library relies on Node Package Manager(NPM) which will help in resolving dependencies. Hope you have latest NPM installed, if not please go ahead and follow the instruction to update NPM from here


  • npm (by default installed when node is installed).
  • node
  • Pepipost library
  • A free account on Pepipost. If you don't have a one, click here to sign-up and get 30,000 emails free every month.

Quick Start

  1. To check if node and npm have been successfully installed, write the following commands in command prompt:

    • node --version
    • npm -version

    Version Check

  2. Since npm is installed, you can directly clone the pepipost reposistory using below command:

    git clone pepi-nodejs


    cd pepi-nodejs
    npm install 


    Once your package is installed, you will see node_modules folder.

  3. The following section explains how to use the library in a new project:

    1. Open Project Folder

      Open an IDE/Text Editor for JavaScript like Sublime Text. The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

      Click on File and select Open Folder.

      Select the folder of your SDK and click on Select Folder to open it up in Sublime Text. The folder will become visible in the bar on the left.

      Open Project

    2. Creating a Test File

      Now right click on the folder name. Select the New File option to create a new test file.

      Save it as test.js. Now import the Pepipost NodeJS library using the following lines of code:

      var lib = require('./lib');

      Save changes.

      Create new file

    3. Copy and paste the code from SampleUsage in example.js file

      Get your API key and Sending Domain from your Pepipost account.

      • apikey will be available under Login to Pepipost -> Settings -> Integration
      • Sending Domain will be available under Login to Pepiost -> Settings -> Sending Domains
  *Note :: Domains showing with Active status on Sending Domain dashboard are only allowed to send any sort of emails.* In case there are no Sending Domain added under your account, then first add the domain, get the DNS (SPF/DKIM) settings done and get it reviewed by our compliance team for approval. Once the domain is approved, it will be in ACTIVE status and will be ready to send any sort of emails. 
  1. Running the test file

    To run the test.js file, open up the command prompt and navigate to the path where the SDK folder resides. Type the following command to run the file:

      node test.js
   "data": {
   	"message_id": "e8820eeb0ee94807f1ce88652b1dd627"
   "message": "OK",
   "status": "success"


'use strict';

const lib = require('lib');
const configuration = lib.Configuration;
const controller = lib.MailSendController;

configuration.apiKey = '4D51B3ECA2D4ED3A67E4E043B3F1A4D1';

let body = new lib.Send();

body.from = new lib.From(); = 'hello@your-registered-domain-with-pepipost'; = 'Pepipost';
body.subject = 'Pepipost Test Mail from SDK';

body.content = [];
body.content[0] = new lib.Content();
body.content[0].type = lib.TypeEnum.HTML;
body.content[0].value = '<html><body>Hello, Welcome to Pepipost Family.<br>My name is [% name %].<br>my love is sending [% love %]</body> <br></html>';

body.personalizations = [];
body.personalizations[0] = new lib.Personalizations();
body.personalizations[0].attributes = JSON.parse('{"name":"Pepi","love":"Email"}');

body.personalizations[0].attachments = [];
body.personalizations[0].attachments[0] = new lib.Attachments();
body.personalizations[0].attachments[0].content = 'SGVsbG8sIHRoaXMgZmlsZSBpcyBhbiBpbmZvcm1hdGlvbmFsIGZpbGU6OiBTZW5kaW5nIGVtYWlscyB0byB0aGUgaW5ib3ggaXMgd2hhdCB3ZSBkbywgYnV0IHRoYXTigJlzIG5vdCB0aGUgb25seSByZWFzb24gd2h5IGRldmVsb3BlcnMgYW5kIGVudGVycHJpc2VzIGxvdmUgdXMuIFdlIGFyZSB0aGUgb25seSBFU1AgdGhhdCBkb2VzbuKAmXQgY2hhcmdlIGZvciBlbWFpbHMgb3BlbmVkLg==';
body.personalizations[0].attachments[0].name = 'personalized-file.txt';

body.personalizations[0].to = [];
body.personalizations[0].to[0] = new lib.EmailStruct();
body.personalizations[0].to[0].name = 'to-address';
body.personalizations[0].to[0].email = '';

body.tags = ['campaign'];

const promise = controller.createGeneratethemailsendrequest(body);

promise.then((response) => {
}, (err) => {
