# AWS::Lambda::EventSourceMapping SchemaRegistryAccessConfig
<a name="aws-properties-lambda-eventsourcemapping-schemaregistryaccessconfig"></a>

Specific access configuration settings that tell Lambda how to authenticate with your schema registry.

If you're working with an Amazon Glue schema registry, don't provide authentication details in this object. Instead, ensure that your execution role has the required permissions for Lambda to access your cluster.

If you're working with a Confluent schema registry, choose the authentication method in the `Type` field, and provide the Amazon Secrets Manager secret ARN in the `URI` field.
