Configuring App Inbox for Websites

Setting up App Inbox for websites includes:

  1. Getting authentication token.
  2. Script installation and initialization.
  3. Integration of a widget displayed on the site.



App Inbox functionality works only for users authorized on the site.

Getting Authentication Token

Send the request from your backend to eSputnik API to receive the authentication token (authToken).
Authenticate the request using one of the methods specified in the API instructions, for example, using an API key.

Request methodPOST
Request headerContent-Type: application/json
Request body{
"email": string,
"phone": string,
"externalCustomerId": string
Response: HTTP 200{
“token”: “string”
Response: HTTP 400/401

The request has to contain the known contact fields: email, phone, externalCustomerId (at least one field is required). Those fields are used for searching a contact in eSputnik. Afterward, the script uses authToken in requests to the eSputnik server.

You can find additional information about managing contacts in API methods for adding contacts.



The token can become invalidated at any moment for security considerations, so you get it more than once. The script renews the token automatically by calling getAuthTokenCallback.
If a contact is not in the eSputnik system, the token is not returned, and the following response comes back instead:

“token”: “”

Script Installation and Initialization

Install and initialize the script on your frontend. Transmit getAuthTokenCallback in the parameters. This shall have the function calling your backend and returning the token.

If you have installed the eSputnik script to work with web tracking, forms and recommendations, you don’t need to reinstall it. Just add parameters for App Inbox to the initialization call.

eS('init', {RECOMS: true, TRACKING: false, APP_INBOX: true}, {getAuthTokenCallback: () => yourImplementationOfAuthCallback(),  language: 'en', });



Call the 'init' initialization command one time at every page loading.

If you have not installed the script before, contact the eSputnik support team to get it, indicating that you need it for App Inbox.

You can get the script by yourself in the Settings > Web Tracking section.

You can learn how to set up a web tracking code here.

Important: Modify the call of the `'init'’ command in the script generated in the Web Tracking section as follows:
instead of


it has to be

eS('init', {APP_INBOX: true}, {getAuthTokenCallback: () =>yourImplementationOfAuthCallback(),  language: 'en', });

Example of a script with initialization:

<script> !function (t, e, c, n) {var s = e.createElement(c); s.async = 1, s.src = '' + n + '.js'; var r = e.scripts[0]; r.parentNode.insertBefore(s, r); var f = function () {f.c(arguments); }; f.q = []; f.c = function () {f.q.push(arguments); }; t['eS'] = t['eS'] || f; }(window, document, 'script', 'UUID'); </script><script>eS('init', {APP_INBOX: true}, {getAuthTokenCallback: () => yourImplementationOfAuthCallback(), language: 'en', });</script>

Parameters of the Object Passed to eSputnik Function

getAuthTokenCallbackfunction yourImplementationOfAuthCallback() {
return new Promise((resolve, reject) => {
// place here code with your backend API request, parse token from response and pass it to resolve function call
resolve('token should be placed here');

type: () => Promise
Asynchronous function called by the script to get authToken. It has to address to the Customer Backend and return Promise
Type: String

Integration of App Inbox Widget

To integrate the widget on the site, the user has to provide to eSputnik:

In addition, you can submit an SVG file with the desired design of the notification icon (Bell button) and the design of notifications.

Also, you can ask eSputnik to develop the design of the bell button and notifications for you.
