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."
Base64String
A (potentially binary) string encoded using base64.
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).
Note
GitRefname is available under the Update refs preview update multiple refs in a single operation 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.
