The iframe sends some message events to its parent’s window object. To receive such events, you need to listen to JS ‘message’ events. Please note that this is not a Kudo specific mechanism but the native JavaScript message event is used so potentially you receive message events from other origin than Kudo iframe.
You can listen for dispatched messages by executing the following JavaScript:
| Code Block |
|---|
window.addEventListener("message", (event) => {
if (event.origin !== "http://example.org:8080")
return;
// ...
}, false); |
The properties of the dispatched message are:
origin - The origin of the window that sent the message. If you are using ARES Kudo SaaS, the origin is “https://app.kudo.graebert.com”.
data - The object passed from the iframe
Kudo sends data as a JSON object with a messageName string and a message object with some message dependent strings.
| Code Block |
|---|
{
messageName: "nameOfTheMessage",
message: {}
} |
