Pay Now Payment MDCs
The Pay Now payment SubMan APIs query payment information and add or remove payment method tokens for subscribers and groups.
For more information about making a payment to a prepaid main balance, see the discussion about main balances in MATRIXX Pricing and Rating.
For more information about subscriber APIs and group APIs, see the discussion in MATRIXX Subscriber Management API.
Note: You cannot remove a payment method if it is associated with a
scheduled recharge or automatic recurring recharge.
