## About scalars

[Scalars](https://spec.graphql.org/June2018/#sec-Scalars) are primitive values: `Int`, `Float`, `String`, `Boolean`, or `ID`.

When calling the GraphQL API, you must specify nested subfields until you return only scalars.

For more information, see [AUTOTITLE](/graphql/guides/introduction-to-graphql#field).
