Group Payment (Pay Now) APIs
The group payment APIs add, query, and delete Pay Now payment information for groups.
Important: When requesting a Pay Now refund, if
the amount causes the main balance to exceed its credit limit, the request still succeeds
and the main balance is charged the full refund amount.
For more information about making a payment to a prepaid main balance, see the discussion about main balances in MATRIXX Pricing and Rating.
