Partial Debits
Increase your revenue by recovering funds that would have otherwise been lost
Introduction
With this feature, when an attempt to charge a card fails with insufficient funds, we will automatically retry with the maximum amount that can be charged. For example, if you attempt to charge someone NGN 10,000 but they only have NGN 4,000 in their account, historically, the transaction will fail with insufficient funds, but with partial debits, we will charge about NGN 3,900,
Allowed Cards
Partial debit is only available for Mastercard and Verve at the moment
