Flags: add or remove one tester without touching the rest of a rule
Add a QA account or an early-access customer to a targeting list, or take them out, without re-sending the rules that target everyone else.
In the console, press Add or remove values under any list condition of a flag’s rules or a segment. Only that list changes, so a slip cannot switch the feature off for the people the other rules target. Each change is one entry in History.
From code, send rule_edits when you update a flag’s value, or condition_edits when you update a segment. Adding a value that is already there, or removing one that is not, changes nothing. The version check still rejects an edit made from an out-of-date read. See Testing.
