Listen to Embedded Preparation events in your iFrame

You can now listen to JavaScript events emitted by Embedded Preparation when it is embedded in an iFrame. Subscribe to window.postMessage on the parent page to react in real time, instead of polling or guessing when your user is done:

• ready: the portal is authenticated and displayed.
• done: your user completed the preparation with the Done button.
• expired: the preparation link or the one-hour session ran out.
• invalid: the link is invalid and could not be opened.
• field.added / field.deleted: a Field was added or removed, fetch the current Fields from the API to get the exact state.
