Get started with installing the Beefree SDK within your web application.

Add JavaScript Library

Congratulations on registering your first application! Now it’s time to install it. The first step is to add the Beefree SDK library to your application. You can use plain HTML or our convenient NPM module.


<script src="" type="text/javascript"></script>


npm i @mailupinc/bee-plugin

Initialize the application

Step 1. Create a container

The embedded application (email builder, page builder, popup builder, file manager) will load into any HTML element on your page.

We recommend starting with an empty div, as follows:

<div id="bee-plugin-container"></div>

Step 2. Authentication

Beefree cares about your security. This is why we use a standard JSON Web Token, or JWT, to authenticate your application.

To authenticate your application, pass your Client ID and Client Secret to our authorization service, and we’ll send your unique token back to you.

We talk about this step in detail here, but here’s a quick example using jQuery:


var endpoint = "";
var payload = {
  client_id: "string", // Enter your client id
  client_secret: "string", // Enter your secret key
  grant_type: "password" // Do not change
$.post(endpoint, payload)
  .done(function(data) {
    var token = data;
    // continue initialization here...

Step 3. Create an application

Now that you have a token, you can initialize the application into your empty div.

To do so, you will call the create method, which has three parameters:

  • token This is the result of the previous step.

  • config This contains your settings and event handlers.

  • callback This is a function that receives the application instance

Here is an example in plain JavaScript:

// Define a global variable to reference the application instance
// Tip: Later, you can call API methods on this instance, e.g. bee.load(template)
var bee;
// Define a simple Beefree application configuration...
var config = {
    uid: 'string',
    container: 'string'

// Call the "create" method:
// Tip:  window.BeePlugin is created automatically by the library...
window.BeePlugin.create(token, config, function(instance) {
    bee = instance;
    // You may now use this instance...

The following table shows all of the required configuration settings:




An alphanumeric string that identifies the user and allows the embedded application to load resources for that user (e.g. images).

  • Min length: 3 characters

  • Can contain letters from a to z (uppercase or lowercase), numbers and the special characters _ (underscore) and – (dash)

  • It is a string and not a numeric value

It uniquely identifies a user of the Beefree application. When we say “uniquely”, we mean that:

  • It will be counted as a unique user for monthly billing purposes.

  • Images (and other files) used by the user when creating and editing messages will be associated with it and not visible to other users (when using the default storage).



Identifies the id of div element that contains the application

Step 4. Start the application

The final step is to start the application, using the start method.

  • If the application is one of the builders, do so by loading a template.

  • If the application is the File Manager, no parameters are needed.

Call the start method as follows:

var template = { ... }; // Any valid template, as JSON object

The instance method bee.start(template) does not need to be called immediately after create. In a SPA (Single Page Application) or React app, you can create the editor in a hidden global state but then call the start method when the template is selected and available. The application loads quickly when all steps are completed consecutively. However, by separating the loading workflow into two parts, the end-user will perceive loading in a fraction of the overall time. Remember, if the client_id belongs to a File Manager application, bee.start() can be called without any parameters.
