Why we recommend GraphQL over REST 

While we support both GraphQL and REST APIs, GraphQL is our recommended integration method and receives new features first. GraphQL offers faster responses, more flexibility, and allows you to request exactly the data you need in a single call. Our REST APIs are considered end-of-life and have limited access to newer features. Learn more about why we recommend GraphQL.
