Graph API
Graph API is a RESTful web API developed by Meta (formerly Facebook) that allows developers to programmatically access data in the Facebook family of apps, including Facebook, Instagram, WhatsApp, and Oculus. It provides a unified interface for querying and manipulating social graph data, such as users, pages, posts, and events, using HTTP requests. The API supports operations like reading, creating, updating, and deleting data, with authentication handled through OAuth 2.0.
Developers should learn Graph API when building applications that integrate with Meta's platforms, such as social media apps, marketing tools, or analytics dashboards. It is essential for use cases like fetching user profiles, posting content programmatically, managing ad campaigns, or accessing insights from Facebook Pages. For example, a developer creating a social media management tool would use Graph API to automate posts and retrieve engagement metrics.
