Meta Ads API, Google Ads API, and TikTok Ads API are platform-specific APIs that let developers manage advertising campaigns, access performance data, and integrate advertising capabilities into internal dashboards, business applications, and automation tools.
In this guide, you'll learn how the Meta Ads API, Google Ads API, and TikTok Ads API compare in terms of capabilities, integration, and limitations. You'll also learn how Zernio, a unified ads API, gives you access to these advertising platforms through a single API or MCP server integration, instead of building and maintaining separate integrations for each platform.

Meta Ads API: Overview
Meta Ads API is a collection of Graph API endpoints that lets developers programmatically create, manage, and analyse advertising campaigns across Meta platforms, including Facebook, WhatsApp, and Instagram. The API enables you to pause and update campaigns, ad sets, ads, and creatives, and retrieve insights and performance data for reporting and analysis.
You can also configure campaign and ad set settings such as budgets, schedules, audiences, and optimisation goals using the Meta Ads API. Before an ad goes live, Meta reviews it to ensure it complies with its advertising standards, and changes to certain elements, including the creative (such as images, text, links, or video), targeting, optimisation goals, or billing events, may pause the ad and trigger another review.
Meta provides a hosted MCP server that lets AI clients interact with its advertising tools through structured, permission-scoped tools. The server exposes tools for campaign reporting, ad and campaign management, catalog management, signals and datasets, Meta Business Help Centre searches, A/B tests and lift studies, and activity logs to AI chat tools.
Key features
- Create campaigns, ad sets, ads, and upload ad creatives programmatically through the Marketing API.
- Modify, pause, and delete campaigns, ad sets, and ads using API requests.
- Create and manage audiences for targeting users based on supported audience criteria.
- Configure bid strategies, optimisation goals, budgets, pacing, scheduling, and billing events for advertising campaigns.
- Retrieve advertising metrics such as impressions, clicks, reach, spend, conversions, and click-through rate.
- Access performance data at the ad account, campaign, ad set, and individual ad levels and filter by dimensions such as age, gender, country, platform, placement, and device.
- Generate reports for specific time periods and campaign criteria to analyse ad performance and identify trends across campaigns, ad sets, and ads.
- Meta MCP server with read and write access to manage ad campaigns.
Pricing
The Meta Ads API does not charge a separate fee for API calls. However, access to some Marketing API capabilities is subject to Meta's access tiers, permissions, and app review requirements.
Limitations
- Limited to Meta platforms.
- Meta regularly updates API versions and capabilities, so you need to monitor the documentation and update your integration for new versions, deprecated fields, and deprecated endpoints.
- API usage is subject to dynamic rate limits that vary by business use case, access tier, and ad account activity.
- API access requires appropriate Meta permissions and access tokens for the requested ad data.
- Meta ads require review before they can go live, and changes to certain ad attributes can trigger another review.
Google Ads API: Overview
The Google Ads API allows developers to programmatically create and manage different types of Google Ads campaigns, including Search, Display, Shopping, and Performance Max campaigns.
Search campaigns can serve ads in Google Search results and partner networks based on relevant search queries, while Display campaigns reach users across millions of websites and apps.
Shopping campaigns promote products across Google's shopping surfaces, and Performance Max campaigns use Google's automated optimisation to serve ads across multiple Google channels from a single campaign.
You can also use the Google Ads API to upload and manage creative assets, configure account-level budgets, manage billing operations, retrieve conversion and audience data, and monitor campaign, ad group, and ad performance.
Google Ads provides a read-only MCP server that lets AI clients retrieve customer names and IDs, campaign and ad group metadata and performance metrics, and analyse Google Ads data using natural language. Google doesn't host the server, so you can either run it locally or deploy it to cloud infrastructure such as Google Cloud Run when you need to make it accessible as a web service or share it across multiple AI agents.
Key features
- Create and manage Google Ads campaigns, ad groups, ads, assets, keywords, users, and audiences programmatically.
- Read-only MCP server for retrieving campaign and ad group data and analysing Google Ads.
- Use Google Ads Query Language (GAQL) to filter, sort, and retrieve specific advertising data.
- Retrieve, apply, and dismiss recommendations for bidding, budgets, keywords, ads, and targeting.
- Access optimisation scores and metrics to identify campaign improvement opportunities.
- Forecast video campaign reach on YouTube and Google Video Partners based on budgets, audiences, and reach goals.
- Access campaign, asset, search term, placement, and product-level data for analysing advertising performance, including Performance Max campaigns.
Pricing
The Google Ads API is free to use, and Google does not charge for API calls. You only pay for the advertising costs generated by your campaigns in your Google Ads accounts.
Limitations
- Limited to Google Ads only.
- Google frequently releases new API versions and deprecates older ones, so you must monitor version changes and update integrations when required.
- API requests and operations are subject to quotas and limits that depend on your developer token access level and the type of operation.
- OAuth authentication and account access can be complex to set up, particularly when managing multiple Google Ads accounts.
- GAQL and the Google Ads API have a learning curve, especially for developers who are unfamiliar with Google Ads account structures and reporting resources.
- Access requirements and developer token approval can add complexity when setting up a production integration.
TikTok Ads API: Overview
TikTok Ads API enables developers to create, manage, and optimise advertising campaigns, ad groups, and ads programmatically. It also supports creative assets, audiences, catalogs, ad account management, and customisable reporting data based on the metrics and dimensions relevant to your analysis.
The TikTok Ads API provides tools for measuring campaign effectiveness and multiple reporting options that analyse campaign and advertising performance, including basic reports, audience reports, Playable Ads reports, Dynamic Showcase Ads reports, Business Centre reports, and GMV Max Ads reports.

Platform-Specific Ads API vs Unified Ads APIs
Platform-specific advertising APIs give you direct access to one ad platform, requiring you to build and maintain each integration. A unified ads API acts as a middle layer across multiple platforms, allowing you to manage cross-platform campaigns through a single integration.
Other differences include:
| Criteria | Platform-specific ad APIs | Unified ad APIs |
|---|---|---|
| Platform coverage | Owned by one advertising platform | Connects to multiple advertising platforms through a single API |
| Integration effort | Requires a separate integration for each advertising platform | One integration provides access to multiple platforms |
| Data structure | Uses each platform's native data structure, metrics, and response formats | Normalises data into a common structure where possible |
| Scalability | Adding a platform requires another API integration | Add supported platforms without building separate integrations |
| API maintenance | Your team manages updates, authentication, deprecations, and API changes for each platform | The provider manages platform integrations and API changes |
| API rate limits | Your application must handle each platform's limits, quotas, pagination, and errors | Abstracts platform-specific limits and optimises requests using automatic retry mechanisms |
| Cost | APIs are free, but multiple integrations add development and maintenance costs | Paid based on connected platforms, accounts, usage, or data volume |
| Best for | Applications that require deep control over a specific advertising platform | SaaS apps, cross-platform ad tools, and unified marketing dashboards |

FAQs
What is the difference between Meta Ads API, Google Ads API, and TikTok Ads API?
Meta Ads API, Google Ads API, and TikTok Ads API are platform-specific APIs. Each provides programmatic access to its own advertising platform, including campaign management, audience targeting, creative management, reporting, and performance data.
Which API is best for managing Meta, Google, and TikTok ads?
Zernio is the best unified API for managing Meta, Facebook, TikTok, LinkedIn, Pinterest, X, and ChatGPT ads through a single integration. It lets you create and update campaigns, manage and monitor ad spend, budgets, and audiences, access ad performance and analytics, and use an ad library to research competitor campaigns.
What is the difference between an Ads API and an Ads MCP server?
An Ads API provides programmatic access that developers can integrate into applications and services. An MCP server exposes advertising capabilities as tools that AI clients and agents can use. Zernio provides both a unified Ads API and a hosted MCP server with read and write access.
Can AI agents manage Google, Meta, and TikTok ads?
Yes, AI agents can use advertising MCP servers to retrieve campaign data, analyse performance, and perform supported management tasks. Zernio provides a hosted MCP server with read and write access across supported advertising platforms.
How do Meta Ads API, Google Ads API, and TikTok Ads API handle authentication?
All three use token-based authentication, but their requirements differ. Google Ads API uses OAuth 2.0 and a developer token, while Meta and TikTok use OAuth-based authentication and access tokens. Zernio abstracts these platform-specific authentication requirements, allowing you to connect supported ad platforms and access them through a single API key.
What are the main limitations of platform-specific advertising APIs?
Each platform-specific API has its own authentication requirements, rate limits, data structures, permissions, API changes, and implementation requirements. Building integrations for multiple platforms therefore requires maintaining each integration separately. A unified API can abstract many of these differences.
