Description

User wants to browse, list, or select Custom Audiences for targeting — DB lists, lookalike audiences, remarketing segments, website visitors, engagement audiences.

Returns all Custom Audiences for the ad account with ID, name, type (subtype), approximate size, and delivery status.

Workflow:
1. Call this tool to discover available custom audiences
2. Use audience IDs with campaign creation tools via `custom_audiences` parameter
3. Optionally use `excluded_custom_audiences` to exclude specific audiences

When to use:
- Before creating campaigns that need custom audience targeting
- When user asks "which audiences do I have?" or "show me my lookalike audiences"
- When setting up remarketing or DB-list campaigns

Request body

All tool arguments are wrapped in an arguments object.

Field	Type	Description
`ad_account_id`	`string` optional	Meta Ad Account ID. Required for multi-account users. Get from list_connected_accounts.
