Schema Registry credentials

You can use these credentials to authenticate the following nodes when you enable Use Schema Registry:

• Kafka
• Kafka Trigger

The Kafka node and Kafka Trigger use a Schema Registry to encode and decode Avro messages. This credential is separate from your Kafka credentials: the registry has its own endpoint and authentication, distinct from the Kafka brokers.

Supported authentication methods

• None
• Basic Auth (username and password), such as a Confluent Cloud Schema Registry API key and secret

Refer to the Confluent Schema Registry documentation for more information about using the service.

Setting up the credential

To configure this credential, you'll need the URL of your Schema Registry and, if it requires authentication, the details to access it.

1. In the URL field, enter the base URL of your Schema Registry, for example https://psrc-xxxxx.region.aws.confluent.cloud.
2. Select the Authentication method:

• None: use this for a Schema Registry that doesn't require authentication.
• Basic Auth: use this for a Schema Registry that requires HTTP Basic Auth, such as Confluent Cloud. Then add:

1. The Username. For Confluent Cloud, this is the Schema Registry API key.
2. The Password. For Confluent Cloud, this is the Schema Registry API secret.
3. Select Save. n8n tests the credential by calling the registry's /subjects endpoint.

To use the credential, open your Kafka or Kafka Trigger node, enable Use Schema Registry, and select this credential.
