When navigating to Data Cloud Setup, the user interface displays a card labeled "Connections" with a numeric count.
This number represents the total aggregate count of MktDataConnection metadata records currently existing in the org. To identify the specific names and details of every connection making up this total, you must query the underlying metadata object using the Tooling API.
Follow the steps below to generate a list of all connections using the Salesforce Developer Console.
Log in to your Salesforce Org.
Click the Gear Icon in the top-right corner and select Developer Console.
In the console window, click the Query Editor tab located in the bottom panel.
Important: Check the box labeled Use Tooling API (located next to the Execute button).
Paste the following SOQL query into the editor:
SELECT CreatedDate, LastModifiedDate, ExternalRecordIdentifier, Id, MasterLabel
FROM MktDataConnection
Click the Execute button.
The Query Results grid will display a list of records.
