Boxed tag
The “iAdvize Boxed Tag” is a way to include the iAdvize Tag in the most secure way, without it having access to the client’s website.
With this solution, the iAdvize tag can be loaded in an isolated box (a sandboxed iframe).
This way, the main page context cannot be accessed by the iAdvize tag: the main page only sends controlled, relevant data to the boxed tag.
Simple installation
This is the simplest way too add the iAdvize Boxed Tag to a website with the default configuration.
1 - Serve this HTML file
Serve a HTML file. We will use the name iadvize-boxed-iframe.html
, but any name can be chosen.
This file needs to be served on the same top domain as the page it will be included in.
Replace <your-sid>
with your own sid.
Ex :
<!DOCTYPE html>
<html>
<body>
<script src="https://static.iadvize.com/boxed-tag/1.4.4/index.js" integrity="sha512-NS7M2FyNHaefJ42ilas6W+t/qJleeGTWIyhM2pj2Pn+t7PgWRH/HarBqV8HT+RFDi6JVS1ReAeF2Afz5dwpBjQ==" crossorigin="anonymous"></script>
<script>
window.iAdvizeBoxedTag.initIAdvizeIframe(<your-sid>, "halc");
</script>
</body>
</html>
2 - Add the following script
Add the following script (in your frontend code, or in your tag manager), replacing https://static.brand-domain.com/iadvize-boxed-iframe.html
with the actual URL of the iframe :
const iAdvizeIframeUrl = "https://static.brand-domain.com/iadvize-boxed-iframe.html";
const style = document.createElement("style");
style.innerHTML = `
#iAdvizeSandboxedIframe {
border: none;
position: fixed;
bottom: 0;
right: 0;
width: 100vw;
height: 100vh;
pointer-events: none;
z-index: 2147483647;
}
`;
document.body.append(style);
const boxedTagScript = document.createElement("script");
boxedTagScript.src =
"https://static.iadvize.com/boxed-tag/1.4.4/index.js";
boxedTagScript.integrity =
"sha512-NS7M2FyNHaefJ42ilas6W+t/qJleeGTWIyhM2pj2Pn+t7PgWRH/HarBqV8HT+RFDi6JVS1ReAeF2Afz5dwpBjQ==";
boxedTagScript.crossOrigin = "anonymous";
const iAdvizeSandboxedIframe = document.createElement("iframe");
iAdvizeSandboxedIframe.sandbox = "allow-scripts allow-same-origin allow-popups allow-forms";
iAdvizeSandboxedIframe.allow = "camera;microphone;autoplay";
iAdvizeSandboxedIframe.src = iAdvizeIframeUrl;
iAdvizeSandboxedIframe.id = "iAdvizeSandboxedIframe";
document.body.append(iAdvizeSandboxedIframe);
boxedTagScript.onload = function () {
window.iAdvizeBoxedTag.initIAdvizeHost("iAdvizeSandboxedIframe");
};
document.body.append(boxedTagScript);
Advanced installation
This is a more advanced installation, allowing :
Install the lib on your project
npm install @iadvize-oss/boxed-tag
Create the iframe script
Create a js file that will import the iframe script.
Then call initIAdvizeIframe
to listen the host messages.
The initIAdvizeIframe
comes with 2 arguments :
sid
: your iAdvize sid.iAdvizePlatform
: the iadvize platform (default: ha).
import { initIAdvizeIframe } from '@iadvize-oss/boxed-tag';
initIAdvizeIframe(<sid>, <iAdvizePlatform>);
Add a boxed iframe
Add a boxed iframe on your site's main page.
<iframe
title="iAdvize chat notification frame"
sandbox="allow-scripts allow-same-origin allow-popups allow-forms"
allow="camera;microphone;autoplay"
src="https://my-iframe-script-url"
id="myIframeId"
></iframe>
The iframe is set with the following sandbox parameters:
sandbox param | description |
---|
allow-scripts | Allows the page to run iAdvize tag script. |
allow-same-origin | Allows the iAdvize tag to access the host cookies and storages |
allow-popups | Allows the iAdvize tag to open links sent by the agent |
allow-forms | Allows the iAdvize tag to submit the visitor email if needed |
And the following allow parameters:
allow param | description |
---|
camera | Allows the boxed tag to ask the camera permission (for video calls) |
microphone | Allows the boxed tag to ask the microphone permission (for video calls) |
autoplay | Allows the boxed tag to launch the video stream automatically |
Add the host script on your site's main page
Create a js file with the host lib import, then call initIAdvizeHost
to listen to the iframe messages.
import { initIAdvizeHost } from '@iadvize-oss/boxed-tag';
initIAdvizeHost('myIframeId');
Communication
The only way to start a communication between the host and the sandboxed iframe is the window.postMessage
method provided by the navigators (see https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage).
warning
The postMessage data is serialized, so functions cannot be sent (see https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage#parameters).
Then, the target of the postMessage calls can listen to the events using window.addEventListener('message')
.
warning
The source of the event should be checked to avoid conflicts and security concerns (see https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage#security_concerns).
Call iAdvize WebSDK methods from host
WebSDK methods cannot be called from the host context because the iAdvize tag is isolated in the iframe : we need to communicate to the iframe what we want to call.
After having called initIAdvizeHost
, a iAdvizeBoxedInterface
object is available in the host window context.
This object sends the method
name and args
to the iframe, that will call the webSDK.
The activate
, get
and on
methods can return a value to the host :
to retrieve it, add a window.addEventListener("message")
and check the e.data.method
property to recognize the method called.
Navigate
window.iAdvizeBoxedInterface.push({
method: 'navigate',
args: [window.location.href],
});
Activate
The host can listen to the result of the activate
call.
For an anonymous authentication:
window.iAdvizeBoxedInterface.push({
method: 'activate',
args: {
authenticationOption: { type: 'ANONYMOUS' },
},
});
window.addEventListener('message', ({ data: { method, activation } }) => {
if (method === 'activate') {
console.log(activation);
}
});
For a secured authentication, the JWE token should be generated on the host side and sent to the iframe :
- the host should listen a
get-activate-auth-token
message initiated by the iframe. - the backend api then gets the JWE token,
- the token is then sent to the iframe inside a
set-activate-auth-token
message.
The get-activate-auth-token
listener allows the iframe to ask for a token refresh if needed.
Example of secured authentication implementation:
const getJweToken = Promise.resolve('myJWEToken');
window.iAdvizeBoxedInterface.push({
method: 'activate',
args: {
authenticationOption: {
type: 'SECURED_AUTHENTICATION',
},
},
});
window.addEventListener('message', ({ data: { method, activation } }) => {
if (method === 'get-activate-auth-token') {
getJweToken().then((token) =>
window.iAdvizeBoxedInterface.push({
method: 'set-activate-auth-token',
args: `${token}`,
}),
);
}
if (method === 'activate') {
console.log(activation);
}
});
Logout
The host can listen to the result of the logout
call.
Example of implementation:
window.iAdvizeBoxedInterface.push({
method: 'logout',
});
window.addEventListener('message', ({ data: { method } }) => {
if (method === 'logout') {
}
});
On
The host can listen to the result of the on
call.
Example of implementation:
window.iAdvizeBoxedInterface.push({
method: 'on',
args: ['visitor:cookiesConsentChanged'],
});
window.addEventListener('message', ({ data: { method, args, value } }) => {
if (method === 'on' && args.includes('visitor:cookiesConsentChanged')) {
console.log(value);
}
});
Off
window.iAdvizeBoxedInterface.push({
method: 'off',
args: ['visitor:cookiesConsentChanged'],
});
Set
window.iAdvizeBoxedInterface.push({
method: 'set',
args: ['visitor:GDPRConsent', true],
});
Get
The host can listen to the result of the get
call.
Example of implementation:
window.iAdvizeBoxedInterface.push({
method: 'get',
args: ['visitor:cookiesConsent'],
});
window.addEventListener('message', ({ data: { method, args, value } }) => {
if (method === 'get' && args.includes('visitor:cookiesConsent')) {
console.log(value);
}
});
