Frequently Asked Questions

What is the Meta Ads API?

└The Meta Ads API (officially the Meta Marketing API) is Meta's programmatic interface for creating, managing, and reporting on ads across Facebook, Instagram, Messenger, and Audience Network. Zernio wraps it in a REST API with sane defaults.

How much does the Meta Ads API cost?

└Meta's API itself is free - you only pay for ad spend. The real cost is engineering: building OAuth flows, managing token refresh, handling rate limits, and staying current with quarterly API deprecations. Zernio's Ads add-on starts at $10/mo on the Build plan.

Do I need Meta App Review?

└No. Direct API access requires creating a Meta App, submitting ads_management, ads_read, and business_management permissions for review. Zernio is an approved Meta Marketing Partner - we handle all of it.

Will my ad account get banned?

└Meta regularly flags accounts that connect to unvetted third-party tools. Our Marketing Partner status and compliant authorization flow reduce this risk dramatically compared to building your own app or using unverified integrations.

Can I boost Instagram posts?

└Yes. POST to /v1/ads/boost with the Zernio postId and platform: 'metaads'. Works for feed posts, Reels, and Stories from a connected Instagram Business account.

Can I create custom audiences with PII?

└Yes. Upload customer lists (email, phone, name) via /v1/ads/audiences/{id}/users - we handle SHA-256 hashing per Meta's requirements so you don't send plain PII. Lookalike audiences and website custom audiences are also supported.

Can I run Meta Ads alongside Google or LinkedIn?

└Yes. One unified /v1/ads endpoint - the platform parameter picks metaads, googleads, linkedinads, tiktokads, pinterestads, or xads. Same JSON structure regardless of platform.

Can AI agents manage Meta Ads through Zernio?

└Yes. Zernio's MCP server includes Meta Ads actions - create campaigns, adjust budgets, pause ads, pull analytics, all accessible from Claude Desktop, Cursor, or any MCP-compatible client.
