Data Type

DOKU defines standard data types to ensure consistent validation across all APIs. Below are the supported types and their patterns.
TypePatternRemarks
Identity^[A-Za-z0-9-_]+sample usage for reference_id, Idempotency-Id
Safe String^[a-zA-Z0-9.-/+,=_:'@%|]will be use generally for all string attribute e.g: name, metadata, etc'
This ensures a predictable and secure structure for all request and response fields.
