+## DeindexTicket API
+
+The minimatch Frontend has a DeindexTicket API that the Open Match Frontend does not have.
+
+DeindexTickets removes the ticket from the matching candidates.
+unlike DeleteTicket, it does not delete the ticket body;
+you can still get the Assignment with GetTicket after Deindex.
+
+To use the Frontend API added by minimatch,
+you need to use [connect-go](https://github.com/connectrpc/connect-go) and `github.com/castaneai/minimatch/gen/openmatch` instead of package `open-match.dev/open-match`.
+Please see [examples/frontendclient](../examples/frontendclient/frontendclient.go).
