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.
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 precison.
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.
