The Manage Connections feature in Zuora Mediation lets you create and maintain reusable connections that can be selected when configuring processors in a meter flow. You can securely connect external data systems such as AWS S3, Snowflake, and Kafka to the mediation platform for use with meters. Connections centralize credential management, support versioning, and enforce validation so your data pipelines remain secure and reliable. When you create a new connection, it starts in the INACTIVE status and cannot be used by meters until it is successfully tested and activated. Activating a connection automatically runs a connection test, and if the test passes the connection moves to ACTIVE and can be referenced by meters. Updating the configuration of an active connection creates a new version in INACTIVE status; when you activate the new version, all previous versions are deactivated so that only one version of a connection is active at a time. Sensitive connection fields such as passwords, private keys, and secret keys are extracted at creation time, stored securely in AWS Secrets Manager, merged back at runtime when a connection is used, and are never returned in API responses. Each connection type has a configurable limit per tenant or entity; attempts to create or activate connections beyond this limit result in an error. Navigate to **Mediation** > **Meters**. 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. Click **Create New** to create a new connection. To edit the connection details of an existing connection, click **Edit**. To activate an existing connection so it will be available for use, click **Activate**. To remove a connection, click **Delete**. A managed connection can be reused by multiple meters and processors and changes to a connection can affect all dependent flows. Before editing or deleting a connection, review which meters use it and plan any required testing. > The Manage Connections feature in Zuora Mediation lets you create and maintain reusable connections that can be selected when configuring processors in a meter flow. ## Docs - [Create HTTP connections in meters](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-http-connections-in-meters.md): Create and configure HTTP connections in Meters, including base URL, authentication, and connection testing. - [Create AWS S3 connections in meters](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-aws-s3-connections-in-meters.md): The AWS S3 connection type in the Manage Connections window lets you register AWS S3 buckets that can be used by meters in Zuora Mediation. - [Create a Zuora-managed S3 connection](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-aws-s3-connections-in-meters/create-zuora-s3-connection.md): Create a single Zuora-managed S3 connection so Zuora can manage the AWS S3 bucket on your behalf. - [Create an external AWS S3 connection](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-aws-s3-connections-in-meters/create-external-s3-connection.md): Create an external S3 connection when you want to use your own AWS S3 bucket. - [Create Snowflake connections in meters](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-snowflake-connections-in-meters.md): Use Snowflake connections to let Mediation connect to a Snowflake account that can be used as a source or target in meters. - [Prepare a Snowflake user and role for Mediation](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-snowflake-connections-in-meters/prepare-a-snowflake-user-and-role-for-mediation.md): Before using Snowflake with Mediation, create a dedicated Snowflake user and assign a default role with the required privileges. - [Define the Snowflake connection](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-snowflake-connections-in-meters/snowflake-define-connection.md): Define a Snowflake connection in Mediation to enable Zuora-managed access to your Snowflake account. - [Configure Snowflake authentication](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-snowflake-connections-in-meters/configure-snowflake-authentication.md): Snowflake connections support password-based authentication and key-pair authentication. On the Authentication step of the wizard, configure one of the authentication options. - [Configure Zuora-managed S3 for Snowflake (Credentials)](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-snowflake-connections-in-meters/config-snowflake-creds.md): Use the Zuora Managed S3 setup using the Credentials option when you want the simplest Snowflake setup. - [Configure Zuora-managed S3 for Snowflake (Storage Integration, Inline)](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-snowflake-connections-in-meters/config-snowflake-storage-int-inline.md): Use these steps when your Snowflake environment uses a storage integration to control access to external S3 locations, but you do not need separate stages for every data flow. - [Configure Zuora-managed S3 for Snowflake (Storage Integration, Stage)](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-snowflake-connections-in-meters/config-snowflake-storage-int-stage.md): Use these steps your Snowflake standards require all external data access to go through named stages. - [Validate and activate the Snowflake connection](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-snowflake-connections-in-meters/validate-snowflake-connection.md): Validate the Snowflake connection and activate it for use in meters - [Create Kafka connections in meters](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-kafka-connections-in-meters.md): Use Kafka connections to let Mediation connect to an external Kafka (or Kafka‑compatible) cluster that can be used as a source or sink in meters. The connection stores the cluster's bootstrap servers, security protocol, and authentication settings so it can be reused across multiple meters. - [Define the Kafka connection](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-kafka-connections-in-meters/kafka-define-connection.md): Define a Kafka connection in Mediation and specify the cluster configuration. - [Security options for Kafka connections](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-kafka-connections-in-meters/security-options-for-kafka-connections.md): Learn how to configure security protocols, SASL mechanisms, and TLS/SSL settings for Kafka connections, including required properties and validation rules. - [Configure Kafka authentication](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-kafka-connections-in-meters/security-options-for-kafka-connections/configure-kafka-authentication.md): Configure how Zuora authenticates with your Kafka cluster using SASL (SCRAM or PLAIN) or TLS/SSL, and review how credentials and certificates are handled securely. - [Validate and activate the Kafka connection](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/manage-connections-in-meters/create-kafka-connections-in-meters/validate-kafka-connection.md): Validate the Kafka connection and activate it for use in meters.
