GraphQL is a query language and runtime for APIs, developed by Facebook in 2012 and later open-sourced in 2015. And it has changed the way we fetch data from our server. Typically, most front-end clients – like React, Angular, Vue, or mobile apps like iOS and Android – use REST APIs to fetch data from the server. REST APIs require more HTTP calls than GraphQL, which leads to over and underfetching.

In token-based architecture, tokens represent the client’s entitlement to access protected resources. Access tokens (or bearer tokens as they're commonly known) are issued by authorization servers after successful user authentication. The tokens are passed as credentials in the request to the target APIs which inform the API that the bearer of the token is authorized to access the API and perform certain actions.

APIs (application programming interfaces) are increasingly acting as the “missing link” to help organizations integrate all their systems, applications, and databases. So how can you take advantage of API integrations for yourself? The answer is API-led connectivity. API-led connectivity is a systematic approach that uses APIs to seamlessly integrate diverse technologies within an organization, enabling efficient data and application access while fostering agility and innovation.

This article is based on Ballerina Swan Lake Update 7.2. Today, I want to share insights into implementing GraphQL subgraphs in Ballerina. But before we dive into coding, let's take a moment to understand GraphQL federation and the problems it solves. Ballerina Swan Lake WSO2 is an open-source and cloud-native programming language optimized for integration GraphQL Federation is a way to build a unified GraphQL API by combining multiple GraphQL services.
