DO NOT USE to create a new campaign. For new campaigns: - Video campaign - `create_meta_video_campaign` - Image campaign - `create_meta_image_campaign` - Carousel campaign - `create_meta_carousel_campaign` Common scenarios: - A/B test ad copy: Different headlines, primary text, or CTAs for the same audience - A/B test creatives: Different images or videos for the same audience - Format testing within one audience: Image vs video ad in the same ad set - Dynamic Creative (DCO): Multiple images + text variations in one ad — Meta auto-optimizes KEY DISTINCTION — add_meta_ad vs add_meta_ad_set: - Same audience, different creative/copy - use THIS tool (add_meta_ad) - Different audience/targeting - use `add_meta_ad_set` instead (creates a new ad set) Ads in the same ad set SHARE: targeting, budget, schedule, pixel tracking. Each ad has its OWN: creative (image/video/carousel), headline, primary text, CTA, landing page. IMPORTANT: You need an ad_set_id from a previously created ad set. Use `list_meta_ad_sets` first if you don't have the ad_set_id. Supports all 3 ad types + Dynamic Creative: - `image`: Different image + copy variation - `video`: Different video + copy variation - `carousel`: Different card set + copy variation - **Dynamic Creative (DCO)**: Pass `image_urls` (2-10 images), `headlines` (up to 5), `primary_texts` (up to 5), `descriptions` (up to 5). Meta tests ALL combinations and optimizes delivery automatically. Dynamic Creative Optimization (DCO) workflow: 1. Create ad set with `is_dynamic_creative=true` via `add_meta_ad_set` 2. Call this tool with `image_urls` (list of 2-10 image URLs), plus optional `headlines`, `primary_texts`, `descriptions` arrays 3. Meta will test all image × headline × text combinations and optimize 4. DCO ad sets support only 1 ad — if the ad set already has is_dynamic_creative enabled, this tool auto-detects it Note: Cannot mix image_urls (DCO) with image_url (single image) or placement-specific images. Standard workflow: 1. Get ad_set_id from prior campaign creation or `list_meta_ad_sets` 2. Write variant ad copy (different headline/primary_text/image) 3. Call this tool with ad_set_id + new creative + copy ## OpenAPI ````yaml /api-reference/openapi.json post /api/v1/tools/add_meta_ad/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/add_meta_ad/execute: post: tags: - meta-ads summary: Add Meta Ad description: >- User wants to add another ad/creative variation to an EXISTING ad set.
