IMPORTANT: This tool modifies REAL ad sets in Meta Ads Manager. Changes take effect immediately. This is the primary tool for: - Changing audience targeting (age, gender, interests, locations) - Excluding placements (e.g., remove Audience Network) - Adjusting budgets at the ad set level - Changing bid amounts - Pausing/resuming specific ad sets - Modifying optimization goals Returns: - Confirmation of updates applied - Summary of all changes made - Ads Manager URL for the ad set When to use this tool: - "Change the targeting on my ad set" - "Exclude Audience Network from placements" - "Update the budget on this ad set to $50/day" - "Pause this ad set" - "Change the age range to 25-45" - "Add interest targeting for fitness" - "Exclude custom audience from this ad set" - "Change bid to $5" - "Update the optimization goal" Parameters: - ad_set_id: The Meta Ad Set ID to update (required) - status: ACTIVE, PAUSED, DELETED, ARCHIVED (optional) - name: New ad set name (optional) - daily_budget: New daily budget in USD (optional, min $1). DO NOT use for CBO campaigns. - lifetime_budget: New lifetime budget in USD (optional). DO NOT use for CBO campaigns. - daily_min_spend_target: CBO only — minimum daily spend for this ad set (use INSTEAD of daily_budget) - daily_spend_cap: CBO only — maximum daily spend cap for this ad set (use INSTEAD of daily_budget) - lifetime_min_spend_target: CBO only — minimum lifetime spend (for lifetime budget CBO) - lifetime_spend_cap: CBO only — maximum lifetime spend cap (for lifetime budget CBO) - bid_amount: New bid amount in USD (optional) - targeting: New targeting spec as JSON (optional) — for placements, audiences, demographics - start_time: New start time ISO format (optional) - end_time: New end time ISO format (optional) - optimization_goal: REACH, LINK_CLICKS, LANDING_PAGE_VIEWS, OFFSITE_CONVERSIONS, VALUE, etc. (optional) **CBO (Advantage Campaign Budget) campaigns:** For ad sets under CBO campaigns, do NOT set daily_budget or lifetime_budget. Use daily_min_spend_target / daily_spend_cap to control spend distribution. Setting daily_budget on a CBO ad set will cause Meta to reject with an error. At least one update field must be provided. Targeting Spec Examples: *Exclude Audience Network:* ```json { "publisher_platforms": ["facebook", "instagram"], "facebook_positions": ["feed", "stories", "reels"], "instagram_positions": ["stream", "story", "reels"] } ``` *Change age and gender:* ```json { "age_min": 25, "age_max": 45, "genders": [1] } ``` (genders: 1=male, 2=female, omit for all) *Add interest targeting:* ```json { "flexible_spec": [{"interests": [{"id": "6003139266461", "name": "Fitness"}]}] } ``` *Exclude custom audience:* ```json { "excluded_custom_audiences": [{"id": "AUDIENCE_ID"}] } ``` Execution time: 2-5 seconds Modifies: Real ad set in Meta Ads Workflow: 1. Use `list_meta_ad_sets` or `get_meta_campaign_details` to find the ad set ID 2. Use `update_meta_ad_set` with the changes you want to make 3. Verify changes in Ads Manager ## OpenAPI ````yaml /api-reference/openapi.json post /api/v1/tools/update_meta_ad_set/execute openapi: 3.1.0 info: contact: email: support@adspirer.com name: Adspirer Support description: >- REST endpoints for every Adspirer tool. Same surface as the MCP server, over plain HTTP for consumers that can't speak SSE (n8n, Zapier, Make, curl, any language's HTTP client). ## Envelope Every request wraps tool-specific input in an `arguments` object: ```json { "arguments": { } } ``` Every response wraps the result in either a success envelope (`success: true`, `data: {...}`) or an error envelope (`success: false`, `error: "..."`, `is_error: true`). ## Authentication Pass your API key as `Authorization: Bearer sk_live_...` on every request. Generate keys at https://adspirer.ai/keys. ## Quota & billing Every successful billable call decrements your monthly tool-call allowance. The current counter is attached to every 200 response under `data.quota`: ```json "quota": { "used": 42, "limit": 150, "tier": "plus", "period_end": "2026-05-01" } ``` When the limit is hit, the API returns HTTP 402 with a full `quota` block including `upgrade_url`. Read-only diagnostic tools (`get_usage_status`, `list_connected_accounts`, `get_connections_status`) are exempt and never consume quota. ## Idempotency Write operations accept an `Idempotency-Key: ` header. A repeated call with the same key returns the cached result rather than executing twice. **Strongly recommended for n8n, Zapier, and any retry-prone client** — it prevents duplicate campaigns when networks misbehave. Generate a fresh UUID per logical operation (not per retry). ## Multi-account users Customers with multiple connected accounts on the same platform (e.g. an agency with 10 Meta ad accounts) must specify which account to use via `ad_account_id`, `customer_id`, `advertiser_id`, or `account_id` depending on the platform. Omitting it returns HTTP 400 with a list of valid account IDs. See `list_connected_accounts` to discover available IDs. ## HTTP status codes - `200` — success (parse `data`) - `400` — tool-level error (surface `error` to users) - `401` — bad/missing API key - `402` — Adspirer quota exhausted - `404` — unknown tool name - `429` — upstream ad platform rate-limited us (Meta/Google/etc.) — retry with backoff - `500` — server error, report to support ## Streaming This endpoint is plain request-response JSON. There is **no SSE, no chunked streaming**. Safe to use from n8n Cloud's HTTP Request node, Zapier Webhooks, Make HTTP module, curl, and every mainstream HTTP library. title: Adspirer REST API version: 1.0.0 servers: - description: Production url: https://api.adspirer.ai security: [] tags: - description: Audit tools name: audit - description: General (Account Management) tools name: general - description: Google Ads tools name: google-ads - description: LinkedIn Ads tools name: linkedin-ads - description: Meta Ads tools name: meta-ads - description: Monitoring & Reporting tools name: monitoring - description: TikTok Ads tools name: tiktok-ads paths: /api/v1/tools/update_meta_ad_set/execute: post: tags: - meta-ads summary: Update Meta Ad Set description: >- User wants to edit an existing Meta ad set's targeting, budget, bid, placements, schedule, or optimization settings.
