To authorize additional access to Salesforce CDP data, you can assign a connected app two new OAuth scopes. With the Perform ANSI SQL queries on Salesforce CDP data OAuth scope, the connected app can perform ANSI SQL queries of Salesforce CDP data on behalf of the user. The Manage Salesforce CDP profile data OAuth scope gives the connected app access to Salesforce CDP REST API data to manage profile records.
Where: This change applies to Lightning Experience and Salesforce Classic (not available in all orgs) in Group, Professional, Enterprise, Essentials, Performance, Unlimited, and Developer editions. Connected apps can be installed in all editions.
How: Assign the OAuth scopes to the connected app that represents your external app.
