About scalars

Scalarsopen in new window are primitive values: Int, Float, String, Boolean, or ID.

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



The Boolean scalar type represents true or false.



The Float scalar type represents signed double-precision fractional values as specified by IEEE 754.


The ID scalar type represents a unique identifier, often used to refetch an object or as key for a cache. The ID type appears in a JSON response as a String; however, it is not intended to be human-readable. When expected as an input type, any string (such as “4”) or integer (such as 4) input value will be accepted as an ID.


The Int scalar type represents non-fractional signed whole numeric values. Int can represent values between -(2^31) and 2^31 - 1.


The Stringscalar type represents textual data, represented as UTF-8 character sequences. The String type is most often used by GraphQL to represent free-form human-readable text.
