checksum
Identifies a specific revision of the $LATEST
version.
When you create a new slot type, leave the checksum
field blank. If you specify a checksum you get a BadRequestException
exception.
When you want to update a slot type, set the checksum
field to the checksum of the most recent revision of the $LATEST
version. If you don't specify the checksum
field, or if the checksum does not match the $LATEST
version, you get a PreconditionFailedException
exception.
