Use the GET /instances/{id} endpoint to export a connector instance in JSON format. For example, 

curl -X GET "https://api.openconnectors.us2.ext.hana.ondemand.com/elements/api-v2/instances/{{INSTANCE ID}}" -H "accept: application/json" -H "Authorization: User {{USER TOKEN}}, Organization {{ORGANIZATION TOKEN}}" 

You can also make the call in our API docs. To export a connector:

1. Go to the SAP Open Connectors Platform API docs page.
2. On the Instances tab, use the GET /instances/{id} endpoint to retrieve the instance JSON.
