Data

Use json format to represent the record related information. Parameter description:

Select: optional. This parameter specifies the returned fields. If not, all fields of a record will be returned by default.
Record: required. This parameter specifies the primary key field for getting a unique record.

Note: If Data has a Select parameter, Select cannot be the name of the primary key field (since the primary key field is already returned by default).
