Replace a value rule set

THIS IS A FULL REPLACE, NOT A PATCH. Meta's update is declarative: the body you send becomes the rule set.

GET /v1/ads/value-rule-sets/{valueRuleSetId} FIRST.
Keep a rule or criterion by echoing its id.
Create one by including the object WITHOUT an id.
Delete one by OMITTING it from the array. There is no warning and no undo.

name and rules are both required for exactly this reason: a partial body would silently destroy every rule left out.

Rule order is semantic: the array order you send is the evaluation order, and only the first matching rule adjusts the bid for an overlapping audience.

Existing rule sets created elsewhere may contain LOCATION_DMA criteria. Those went inert on 2026-06-22 and are rejected here; migrate them to LOCATION_COMSCORE_MARKET.
