Ids and dates

An id is 24 hexadecimal characters, sent and returned as a string. A value that is not a well-formed id where one is expected is a 400, or reads as "not found".

A date is returned as an ISO 8601 string in UTC, for example 2026-10-01T09:30:00.000Z. Where a route accepts a date it accepts an ISO 8601 string; a route that also accepts a time in milliseconds says so.

Field names are the stored ones and are not uniform: a task carries TaskName, ProjectID and Task_Priority beside sprintId and statusKey. Use the names exactly as each route shows them.
