# Update Audience

`PATCH /v2/campaigns/{id}/audiences/{audience_id}`

Updates an audience's enabled status, description, targeting rule, variant optimization, or variants. Provide a structured `rule_conditions` rule to update targeting: it is compiled into the audience's expression and drives `expression_cel` for modern SDKs, and the audience is switched to the rule editor so it stays in sync with the dashboard. The legacy raw `expression` field is no longer accepted. When variants are provided they replace the existing set. Requires campaigns:write scope.

## Path parameters

- `id` string, required — Campaign ID
- `audience_id` string, required — Audience ID

## Request body

- object
  - `enabled` boolean — Whether this audience is enabled
  - `description` string, nullable — Human-readable description of the audience
  - `rule_conditions` RuleConditions — Structured audience targeting rule (the dashboard rule-editor AST). Compiled server-side into the runtime expression and `expression_cel`. Provide an empty `conditions` array to match all users.
