Meta REST API

Updated: Jul 6, 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 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, the framework provides a consistent, predictable, and standardized interface that simplifies development, maintenance, and integration. The framework is designed to align with modern API design principles and best practices. It is 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 expansion across messaging, virtual reality, and AI, and to 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 already supports new Meta products, including the Llama API⁠ for large language models and Fediverse⁠ integrations. These integrations expand Meta’s AI capabilities.

What to expect

As Meta rolls out the REST API framework, here is what to expect across availability, migration, authentication, documentation, and support:
  • Availability: Starting July 1, 2025, Meta will build new APIs 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. Meta will communicate any migration plans well in advance.
  • Authentication: Some new RESTful APIs use different authentication methods. Meta will document any changes 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.
  • Connect with the developer community for support and best practices.
