Webhook data from Ideas is split in two messages and is missing Category and custom fields

When a new Idea is added in the Ideas Portal, we get 2 separate "added idea" HTTP requests. The first only contains the Description field. The second contains the Name field and a few other fields. This makes it very difficult to take an action in response because we need to store the first part and wait (and hope) for a second request. All of these fields should be in a single HTTP request.

Also, we need the Idea Category and customer fields added to the (single) HTTP request.

Below is an example:

 "event" : "audit", 
 "audit" : {
 "id" : "6238786204232882123",
