About scalars

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 "Introduction to GraphQL."

Boolean

Represents true or false values.

Date

An ISO-8601 encoded date string.

DateTime

An ISO-8601 encoded UTC date string.

Float

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

GitObjectID

A Git object ID.

GitRefname

A fully qualified reference name (e.g. refs/heads/master).

Preview notice

GitRefname is available under the Update refs preview. During the preview period, the API may change without notice.

GitSSHRemote

Git SSH string.

GitTimestamp

An ISO-8601 encoded date string. Unlike the DateTime type, GitTimestamp is not converted in UTC.

HTML

A string containing HTML code.

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.

PreciseDateTime

An ISO-8601 encoded UTC date string with millisecond precision.

String

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

URI

An RFC 3986, RFC 3987, and RFC 6570 (level 4) compliant URI string.

X509Certificate

A valid x509 certificate string.
