Problem

-- Is it possible to update KPS value though a policy?

-- Which filter to use?

Resolution

* There is no default filter which enable to update KPS value.

* The REST API to update KPS (documentation about it can be found in [apigateway_home]/docs/restapi/APIGatewayAPI/api/rest/kps.html) has to be used. The call to this REST API can be done with a "Connect to URL" filter.
