Upward’s components communicate with the parent application using iframe messages.
Partners can listen for these messages and take appropriate actions within their app or browser.

Listening for Messages

Add the following code block to the browser console window to see the messages

1 window.addEventListener("message", (event) => {
2   const { Event, body } = event.data;
3 
4   switch (Event) {
5     case "component.navigation":
6       console.log("Navigation detected", body);
7       break;
8 
9     case "component.closed":
10       console.log("The component was closed", body);
11       break;
12 
13     case "component.alert":
14       console.log("Alert received", body);
15       console.log(body.message || "Component alert");
16       break;
17 
18     case "plaid.token":
19       console.log(body || "Component Plaid");
20       break;
21 
22     default:
