External application front-end can embed Pricefx front-end. Pricefx front-end will be then rendered inside of an iframe of the external application.

This enables Unity to be used in other platforms, and also there is messaging support through the usage of postMessage method (https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage). In order to use it, please check it here: Messaging API.

Below, you can find a simple example of its implementation.

Implementation example

As you embed Unity inside another is an example how to embed Pricefx inside an external application:

<iframe
  src = "https://{partition}.pricefx.com"
  id = "pfx-iframe"/>

You can start using it with the code below:

const
iframe = document.getElementById('pfx-iframe');
const messageHandler = (event) => console.log(event.data);
window.addEventListener(messageHandler);
iframe.contentWindow.postMessage({
  "source": "pfxParentMessage",
  "type": "getUserData"
}, *);

In this case, you will attach a handler that logs the message it receives from Unity, and also will message Unity requesting the logged in user data.

On the other side, if you have an external application embedded in Unity:

const messageHandler = (event) => console.log(event.data);
window.addEventListener(messageHandler);
window.parent.postMessage({
  "source": "pfxParentMessage",
  "type": "getUserData"
}, *);

 sandbox = "allow-forms allow-modals allow-popups allow-same-origin allow-scripts"
/>

Parameters for the iframe:

The external application front-end can communicate with Pricefx front-end through the Unity Messaging API.
