Hi,
I know that Figma emitted events so that developers can listen to some of the event that Figma notifies, but how do I know if the prototype is presenting the last frame?
Thank You!
This is only available when running a plugin and using the plugins API, which is not accessible in embeds. There is no way to listen to events in embeds.
Figma recently updated the documentation for embeds.
https://www.figma.com/developers/embed#:~:text=Events%20emitted%20from%20the%20embed
Store the nodeId value of the last frame and compare it with the presentedNodeId value that is available in the event message data with the PRESENTED_NODE_CHANGED type. Or with targetNodeId in a message with the MOUSE_PRESS_OR_RELEASE type.
Oh wow cool!
Sorry for the late respond.
Thank you but, how do I get that nodeId? If I’m trying to get that from the NEW_STATE event, the nodeId is not the same as the presentedNodeId that emitted from PRESENTED_NODE_CHANGED event.
Here’s how I handle that:
window.addEventListener('message', event => {
const { type, ...rest } = event.data;
if (!type) return;
if (type === 'NEW_STATE') {
console.log(
'[NEW_STATE] event.data.data.nodeId:',
event.data.data.nodeId
);
return;
}
if (type.includes('PRESENTED_NODE_CHANGED')) {
const { presentedNodeId } = rest.data;
console.log(
'[PRESENTED_NODE_CHANGED] presentedNodeId:',
presentedNodeId
);
}
});
And this is the logs:
Get the nodeId of the last frame manually (for example, from a prototype or design link) and hardcode it.
This is a new API that I think is just starting to develop. Perhaps more features and data will be added in the future.

Right, Thank you!!
I have similar question. I was able to know and compare it with the last node id. However, there is a scenario where the last FRAME has 2 buttons (Button A and Button B).
If they click on Button A. I want to notify the parentWindow (where prototype is running) that the “User is done interacting with a prototype. So close the prototype”
If they click on Button B. I want to continue showing next-page.
