Define a Kafka connection in Mediation and specify the cluster configuration.

1. Navigate to Mediation > Meters.
2. Click the Manage Connections button at the top of the page.
   The Manage Connections window is displayed and lists all existing connections with the connection details.
3. Click Create New to create a new connection.
4. From the list of connection types, select Kafka and then click Continue.
5. In the Basic Information section, provide the Connection Name (required) – A name for the connection.
   It must be unique across all connections.
6. In the Cluster Configuration section, under Bootstrap Servers, enter at least one Kafka broker in the host:port format. For high availability, you can add 2–3 brokers using the Add button.
   kafka-01.acme.com:9092
   Zuora connects to the host:port values you configure. Ensure your network or security group allows inbound connections from Zuora IP ranges to those host and port combinations. Internally, this field maps to the bootstrapServer parameter, which is sent as a comma‑separated list of broker addresses. For example, broker1:9092,broker2:9092.

   Kafka connections enforce the following validation rules for bootstrap servers:

   • bootstrapServer is always required; missing or empty values are rejected.
   • Each entry must include a valid port; hostnames without a port, or ports outside the valid range (1–65535, including 0), are rejected.
   • Invalid host/port formats are rejected; valid IPv6 host:port formats are accepted.
7. Click Save & Continue.
