Steps
POST to /act_{ad_account_id}/adrules_library with evaluation_type (SCHEDULE or TRIGGER) and one or more filters (field/operator/value) scoping which campaigns, ad sets, or ads the rule applies to.
Define execution_spec.execution_type as one of PAUSE, CHANGE_BUDGET, CHANGE_BID, CHANGE_CAMPAIGN_BUDGET, NOTIFICATION, UNPAUSE, or another supported action, plus execution_options for the action's parameters.
For SCHEDULE-based rules, set schedule_spec.schedule_type (DAILY, HOURLY, SEMI_HOURLY, or CUSTOM) and the days/start_minute/end_minute evaluation windows.
Submit with a name for the rule; the response returns the new AdRule's id via read-after-write.
Update an existing rule with POST /{ad_rule_id}, or retrieve its run history via the /{ad_rule_id}/history edge to audit past executions.
Known gotchas
Rules whose execution_type turns off ads (e.g. PAUSE) cannot include cost-based conditions — attempting this returns error subcode 2703.
Rule creation/update can fail with error 368 ('deemed abusive or otherwise disallowed') if conditions or actions resemble spam-like automation patterns; test with narrower scopes first.
Rules only evaluate against ad objects already accessible to the token's permissions — a rule silently has no effect on entities outside the associated ad account's scope.
