Disburse

Xtrm Choice™

Everybody likes to have a choice. When you use our API to disburse funds to beneficiary wallets, you can offer up a choice of transfer options such as Bank EFT, Bank Check, Virtual Visa, digital gift cards and more. You can offer any one or all of these options to give your partners and users choice. We call this Xtrm ChoiceTM.

Xtrm Direct™

If, for compliance or other business reasons, you want to directly control how payees receive payment, we offer Xtrm DirectTM. When you use Xtrm DirectTM, you can make payments and disburse to the payee directly to a specific payment option. An example might be direct payments to a bank account or pre-paid virtual Visa cards.
