Headers

Description

Add an audience signal to an existing Performance Max campaign. Audience signals hint Google AI about who your ideal customers are. Uses in-market segments (actively researching), affinity segments (long-term interests), and custom audiences (remarketing lists, customer match). Use search_audiences tool first to discover relevant audience segment IDs. **Parameters:** - campaign_id: The PMax campaign ID - audience_config: Dict with segment IDs **Execution time:** 2-5 seconds

Request body

All tool arguments are wrapped in an arguments object.

FieldTypeDescription
campaign_idstring requiredThe Google Ads campaign ID (numeric). Example: '21854471508'
audience_configobject optionalAudience configuration with segment IDs. CRITICAL: Only use IDs returned by search_audiences tool. NEVER fabricate or guess IDs -- wrong IDs target unrelated audiences. Canonical keys: 'in_market_audience_ids' (List[int]), 'affinity_audience_ids' (List[int]), 'custom_audience_ids' (List[str] customAudiences resource names), 'user_list_ids' (List[str] userLists resource names from search_audiences custom results), 'audience_name' (str). Example: {'in_market_audience_ids': [80432, 80210], 'user_list_ids': ['customers/123/userLists/456'], 'audience_name': 'SaaS Buyers'}. Input is shape-tolerant (#559): synonyms 'user_interests'/'in_market_audiences', 'remarketing_lists'/'user_lists', and 'name'/'signal_name' are accepted, as are flat (no wrapper) and nested 'segments' shapes — they are normalized for you.
customer_idstring optionalGoogle Ads customer ID. Required for multi-account users. Get from get_connections_status.
