Stats calculated based on data on gs.statcounter.com from December 2018
100% compatibility is possible, but implies adding quite a few additional polyfills. We opted for a leaner SDK instead of supporting old and mostly unused browser versions.
Our SDK weighs around 500kb.
Overview
After following the instructions below, your html will look approximately like this:
1
<html>
2
​
3
<head>
4
  ...
5
  <link rel="stylesheet" type="text/css" href="path/to/appsmiles-sdk.css" />
6
  ...
7
</head>
8
​
9
<body>
10
  ...
11
  <div id="apm-sticker"></div>
12
  ...
13
​
14
  ...
15
  <script>
16
    var apmConfig = {...};
17
  </script>
18
  <!-- or <script src="path/to/apm-config.js"></script> -->

  <script src="path/to/appsmiles-sdk.js"></script>

Vocabulary
I. Installation
We generally create a release personalized for your needs. Contact us to get the SDK files.
In order for everything to work properly, we require that the folder we provide be integrated as-is. Do not move the files inside, or some paths will be broken.
II. Configuration
There are 3 different HTML tags to add to your html for the SDK. They must be put in the following order:
1. Style (appsmiles-sdk.css)
One file:
appsmiles-sdk.css
The SDK comes with it's own stylesheet (1st file). All of the class and ids are prefixed with apm- in order to prevent interference in the global scope.
1
<head>
2
    ...
3
    <link rel="stylesheet" type="text/css" href="path/to/appsmiles-sdk.css" />
4
</head>
Copied!
Don't hesitate to contact us if you would like style changes
If instead you see squares instead of icons, this means that the icon font wasn't properly configured in the BO.  Same thing if you see raw text appearing with no style (temporarily, or permanently) where the sticker is supposed to be. This can often happen when files are loaded asynchronously, in which case you have to load these files synchronously in respect to each other (see Ajax and other asynchronous integrations).
​
 
 
(left) No icons (right) No SDK CSS
2. Configuration (apmConfig)
There are many configuration options, some required and others optionals. There are also configuration to help during the development process.
You can externalize this variable into its own JS file, as long as it is called before the main JS file
1
var apmConfig = {    
2
      
3
    // Required
4
    apiBaseUrl: "[Required] {string} URL of the appsmiles API, modify to point to sandbox or prod environment",
5
    clientSignature: "[Required] {string} Signature created with HmacSHA256(timestampString, partnerSecretString).toString().substring(0, 15).toUpperCase();",
6
    clientSignatureTimestamp: "[Required] {number} Timestamp used for client signature creation",
7
    lang: "[Required] {string} Language in which the SDK should be. 2 letter country code.",
8
    openFrom: "[Required] {string} Direction from which the SDK should open (N, NNE, NE, ENE, E, ESE, SE, SSE, S, SSW, SW, WSW, W, WNW, NW, NNW, C)",
9
    partnerId: "[Required] {string} ID of the partner in the appsmiles back-office",
10
    closeIconPosition: "[Required] {string} Position of the close icon. Same values than openFrom. Keep empty field (default) to hide.",
11
    ribbonDirection: "[Required] {string} Direction towards which the notification ribbon should extend (N, E, S, W)",
12
    
13
    // Conditional (scenario specific)
14
    showBalanceInSticker: "[Conditional] {boolean} Whether to show the user's balance in the sticker",
15
    
16
    // Optional
17
    defaultSticker: "[Optional] {string} Absolute or relative url of the image to use for the default sticker, can be configured in the BO too. Needed if you want to change the sticker according to screen width and height",
18
    stickerNotificationBadgePolicy: "[Optional] {number} Policy as to when to show the notification badge on the sticker. -1: never show, 0: always show, 1: show when new content available"
19
    playStickerAnimationOnReload: "[Optional] {boolean} If the sticker is a Lottie animation, play it only the first time the user come on the website. Default is false",
20
    waitForInit: "[Optional] {boolean} If needed, the sdk can be initialized by the client when he decided, with the apmApi.init() method. Default is false"
21
    
22
    // Development
23
    enableLogs: "[Dev] {boolean} Enable logs, overrides the appsmiles debugMode setting",
24
    logLevel: "[Dev] {string} Set log level (verbose, debug, info, warn, error)",
25
    forceRefresh: "[Dev] {boolean} Bypass the waiting time (default: 5 minutes) between API checks on page reload",
26
    forceDeeplink: "[Dev] {string} Force the deeplink button to appear and to redirect to link in variable",
27
}

3. Generating the clientSignature(required)
Among the required options in apmConfig, there is the clientSignature. You will find below what you need to know to generate this signature.
In order to enforce a higher degree of security, our SDK uses JSON Web Tokens (JWT) to encrypt requests sent to our server.
To do that, we need a signature. However, since Javascript code is completely visible to the client, the signature must be generated by your server.
This signature must be generated server-side, in the language your server uses (e.g. PHP, Ruby). It must not be calculated client-side (browser).
Signature type: HMAC SHA-256.
Arguments: timestamp (current time) and the partnerSecret key that we will have provided to you.
Post-processing: Keep first 15 characters and convert to uppercase.
JS
PHP
1
HmacSHA256( // using CryptoJS library
2
  timestamp: string, // ! Very important for it to be a STRING
3
  partnerSecret: string)
4
  .toString()
5
  .substring(0, 15)
6
  .toUpperCase();
Copied!
1
<?php
2
​
3
$partnerSecret = <PARTNER_SECRET>;
4
$clientSignatureTimestamp = (new DateTime())->getTimestamp();
5
$rawClientSignature = hash_hmac('sha256', $clientSignatureTimestamp, $partnerSecret);
6
$clientSignature = strtoupper(substr($rawClientSignature, 0, 15));
7
// TODO: make $clientSignatureTimestamp and $clientSignature available to the client
Copied!
The signature must be regenerated on each page load. The timestamp is only valid 10 minutes.
Now on the client side, you add clientSignature and clientSignatureTimestamp in the apmConfig object:
1
<script>
2
    apmConfig.clientSignature = <clientSignature>;
3
    apmConfig.clientSignatureTimestamp = <clientSignatureTimestamp>;
4
</script>
Copied!
4. The SDK (appsmiles-sdk.js)
This is the main JS file, containing the logic, and UI elements (except the styling).
1
<script src="path/to/appsmiles-sdk.js"></script>
Copied!
5. HTML anchor
The SDK will look for a div with the id 'apm-sticker' like so : <div id="apm-sticker"></div>.
Place this anchor where you wish the button to appear.
The design of the sticker, the placement of the modal and the direction of the notifications are all configured in the style file.
III. Initialization
The SDK initializes itself automatically when the 4. The SDK script tag is executed.
Hurray !
Ajax and other asynchronous integrations
If you are not loading through HTML tags, make sure that the order is respected.
The most important is that the stylesheets and config  are fully loaded before  appsmiles-sdk.js is loaded.
If the order is not respected, you may see:
A bunch of text appearing where the sticker is supposed to be (CSS was not loaded in time)
Console errors about apmConfig
Here is a very basic example of asynchronous loading in one of the correct order:
appsmiles-sdk.css > apm-config.js > appsmiles-sdk.js
1
var loadApm = function () {
2
  var cssSdk = document.createElement('link');
3
  cssSdk.rel = "stylesheet";
4
  cssSdk.type = "text/css";
5
  cssSdk.href = "./appsmiles-sdk.css";
6
  cssSdk.onload = function () {
7
    var scriptConfig = document.createElement('script');
8
    scriptConfig.src = "./apm-config.js";
9
    scriptConfig.onload = function () {
10
      window['apmConfig'].clientSignature = createClientSignature();
11
      var scriptSdk = document.createElement('script');
12
      scriptSdk.src = "./appsmiles-sdk.js";
13
      document.head.appendChild(scriptSdk);
14
    }
15
    document.head.appendChild(scriptConfig);
16
  }
17
  document.head.appendChild(cssSdk);
18
}

loadApm();
