JavaScript HTTP Post Request via a Action Button

Hello
I’d like to add an Action button on the form view of a Ragic sheet/record that when pressed, sends the Ragic unique nodeId via an HTTP post request to a predefined webhook.

This would allow for an on demand update to my website using an ‘Integromat Webhook’ as the initial trigger to start the process, rather than using the built-in Ragic webhooks that fire with every save.

Any help on this would be much appreciated. Most of what I do is via a no-code approach so I have very little knowledge of JavaScript.

Thanks
