time_interval	Yes	Integer	Period of time for limiting the number of API calls. This parameter applies with each of the preceding three API call limits. The maximum value is 2,147,483,647. Enter a positive integer.
time_unit	Yes	String	Time unit, which can be: SECOND MINUTE HOUR DAY
remark	No	String	Description of the request throttling policy The description cannot exceed 255 characters.
type	No	Integer	Type of the request throttling policy, which can be: 1: exclusive, limiting the maximum number of times a single API can be called within the specified period. 2: shared, limiting the maximum number of times all APIs can be called within the specified period.
enable_adaptive_control	No	String	Enabling status of dynamic request throttling TRUE FALSE This function is currently not available.
