Define resource attributes with connectors in Amazon SAM

Resource attributes can be defined for resources to specify additional behaviors and relationships. To learn more about resource attributes, see Resource attribute reference in the Amazon CloudFormation User Guide.

You can add resource attributes to your embedded connector by defining them on the same level as your connector properties. When your Amazon SAM template is transformed at deployment, attributes will pass through to the generated resources.
