How to use the Data Connections tab
Use the Data Connections tab to configure connection information to a database. The connection string is encrypted when saved to the database.
- From the menu on the left, select System Settings, then Data Connections.

 - Click Add New Connection to add a new connection. To view or edit an existing data connection, select the connection from the Connection Name
 - Enter a connection name and description for the connection. This helps you identify the data connection if you connect to more than one database.
Note: The only connection type available currently is REST/OAUTH. The only grant type currently is client_credentials. - Enter a client ID and client secret. This information is issued to the client during the application registration process.
 - Enter the scope of the access request that manages permissions to protected resources.
 - Enter the resource of the access request.
 - Click Test Connection to ensure your settings are correct.
 - Click Save when you've completed your changes.
