Trigger webhook when a select field value changes from one status into another

Hello, I’d like to know if there’s a way to trigger a webhook only when a field value (a select in this case) changes from a previous value to a new one.

What we want to do is:

  1. Create a document.
  2. Trigger a webhook only when the select field value changes (example: from Requested to Responded).

The problem is that we can’t do checks to what the previous value was before triggering the webhook.

We also checked server scripts, but we couldn’t find a way to trigger a webhook from those.

Does anyone have an idea?

We’ve also considered moving this into a lambda/micro, but we’d rather use the provided tools first.
