API Maintenance for User GET Calls

Our reliability engineers have released a performance upgrade to our most popular API endpoint: Users. As a consequence, changes to Smart List criteria may not be immediately reflected in User GET requests. This does not affect the user’s actual status on a Smart List or any actions based on Smart List membership. Accordingly, sends and reports based on the user’s actual realtime list membership status will be unaffected. Going forward, all status changes will be reflected in User calls no later than 5 minutes after a Smart List criteria update. Thank you for your understanding as we improve the performance of the system for everyone.
