Understanding Linear Identifiers

Linear uses two types of identifiers for issues:

• Human-readable identifier (e.g., ALL-1234): Displayed to users, used in search queries. This is the team key + number.
• UUID (e.g., a1b2c3d4-e5f6-7890-abcd-ef1234567890): Required for all mutations (update, comment, etc.). Returned as id in query results.
