adjustPoints( )

Adjusts the point balance of a loyalty account.

について adjustPoints() function returns a Promise that resolves to the updated loyalty account.

To adjust the points balance of an account you must include an accountId, a revision number, and the adjustment to make. You can also leave a description to explain the reason for the points adjustment.

There are two ways to adjust the points of a loyalty account:

• balance allows you to set the total points balance to this new amount. The transaction タイプ will return as "ADJUST".
• amount allows you to alter the points balance by this amount. This amount can be a positive number to increase the points balance or a negative number to decrease the balance. The transaction type will return as "GIVE".

An account may not be adjusted to a negative balance. If you pass values in both the balance そして amount parameters then the balance adjustment takes effect and the amount adjustment is ignored.
