GitRefname is available under the Update refs preview. During the preview period, the API may change without notice.
An ISO-8601 encoded date string. Unlike the DateTime type, GitTimestamp is not converted in UTC.
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.
Represents non-fractional signed whole numeric values. Int can represent values between -(2^31) and 2^31 - 1.
Represents textual data as UTF-8 character sequences. This type is most often used by GraphQL to represent free-form human-readable text.
