Adding javascript event listener to E-signature popup

[messly]

Hello,

I’m trying to add a javascript event listener to my page, which triggers an action when an e-signature is completed in a third party embedded iFrame.

Foe e.g. here is the guidance they provide for listening to a signature on completion.

client.on(‘sign’, (data) => {
console.log(‘The document has been signed!’);
console.log('Signature ID: ’ + data.signatureId);
});

How do I take this listener and allow it to trigger an action in Bubble? Is it a combination to Toolbox and Bubble to JS?

Any help much appreciated.

You’ll probably need to fire an http request from the origin.
