GraphQL queries and mutations GraphQL uses a specific query format, called a “mutation query,” to create, update, or delete elements from a data set.

More flexible and more efficient than REST, GraphQL enables a more streamlined API architecture. Use GraphQL with Ballerina and Choreo for seamless integration.

But it's more than just a protocol: The Graph also has an implementation, which is open source and uses GraphQL. GraphQL is a query language for APIs, developed and open sourced by Facebook.
