AuthAuthenticated Bearer token or console session with X-CSRF-Token · requires task:read

The variables declared in the task’s own scope (its input mappings and local variables). Filter by name, sort by name, value, scopeKey, processInstanceKey or variableKey. Values are JSON text; values longer than 8192 characters are cut and flagged isTruncated unless truncateValues=false. Variables are read from the history projection.
