Meta REST API

Updated: Mar 16, 2026

The Meta REST API is a modern, flexible, and developer-friendly way to build and integrate with Meta's diverse platforms.

What is the Meta REST API?

The Meta REST API framework is a new API platform built to support current and future development needs. It follows the widely adopted REST architectural style, using standard HTTP methods like GET, POST, PUT, and DELETE to enable straightforward communication between clients and servers.

Built on the OpenAPI standard, this framework provides a consistent, predictable, and standardized interface that simplifies development, maintenance, and integration. It is designed to align with modern API design principles and best practices — not a reintroduction of the deprecated REST API from 2011.

Why use the Meta REST API?

Meta's ecosystem has expanded beyond the social graph into messaging, virtual reality, AI, and more. To support this growth and improve your developer experience, the REST API framework offers:

• Contract-driven approach for enhanced schema stability and better documentation
• Alignment with industry standards for easier adoption and interoperability
• Simplified integration to accelerate your development cycles

The framework is already powering new Meta products, including the Llama API⁠ for large language models and Fediverse⁠, expanding Meta's capabilities in AI.

What to expect

• Availability: Starting July 1, 2025, new APIs will begin to be built on the REST API framework. Llama API is already using it. Initially, this applies to APIs without Graph API dependencies. From January 2026, all new third-party APIs will use this framework.
• Migration: If you currently use Graph API, no immediate action is needed. Existing integrations will continue to work. Migration plans, if any, will be communicated well in advance.
• Authentication: Authentication methods may change for some new RESTful APIs. Any changes will be clearly documented with each API release.
• Documentation: New REST APIs will be fully documented on the official Developer Portal, including endpoint references, usage guides, and code examples to help you get started quickly.
• Support: Existing developer support channels remain your primary resource. Meta will provide guidance on support options for new REST APIs, typically through Developer Community Forums and reporting tools.

Getting started

To begin working with the Meta REST API:

• Explore the Developer Portal for the latest API documentation and examples.
• Use the provided SDKs and tooling to streamline your integration.
• Engage with the developer community for support and best practices.
