[Bug] Requesting changes to 'Create a Campaign Filter' (create-campaign-filter)

[jason545454]

1. Create Campaign Filter should not have 'id' in body, as you are creating a new filter, so ID is set by IDN.

2. description is not required, as it successfully creates filters without it.

3. This page should explain or give definitions of the following attributes

"negateResult": false,
"shortCircuit": false,
"recordChildMatches": false,
"suppressMatchedItems": false,

Also, if campaign filter already exists, then error message returned is very unhelpful. It should say filter already exists, and not 'The request was syntactically correct but its content is semantically invalid.'
