Validate messages for a topic

Ensure that messages produced to a topic are validated against a schema, and reject messages that don’t conform.

Prerequisites

A schema registry configured in the Event Gateway control plane.

Set up the policy

curl -X POST https://{region}.api.konghq.com/v1/event-gateways/{eventGatewayId}/virtual-clusters/{virtualClusterId}/produce-policies \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer $KONNECT_TOKEN" \
    --data '
    {
