Scalars

Scalars are primitive values such as Int or String. For more information, see the GraphQL spec.
Scalar Definition
Boolean

Represents true or false values.

Decimal

A signed decimal number, which supports arbitrary precision and is serialized as a string.

Example values: "29.99", "29.999".

Float

Represents signed double-precision fractional values as specified by IEEE 754.

ID

Represents a unique identifier that is Base64 obfuscated. It is 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 "VXNlci0xMA==") or integer (such as 4) input value will be accepted as an ID.

Int

Represents non-fractional signed whole numeric values. Int can represent values between -(2^31) and 2^31 - 1.

String

Represents textual data as UTF-8 character sequences. This type is most often used by GraphQL to represent free-form human-readable text.

Void

A void type that can be used to return a null value from a mutation.
