XPay

10min

﻿
Use XPay to transfer funds directly between 2 different partners inside the Cross River operating system (COS). Because you are transferring funds inside COS, the transfer happens immediately. Funds do not leave the bank with XPay transfers. A transfer can be a push or a pull.
XPay APIs are found in the XPay module of our COS sandbox.
By default, when XPay is enabled, push transactions are turned on and pull transactions are turned off.

Originate an XPay payment
Sends a payment from one Cross River partner to another within the CR system.
When you originate an XPay payment, be sure that the receiving account is enabled to accept XPay transfers. For the receiverIdentifier value you usually use the account number of the account you want to send funds to. If the receiving account is set up with the XPay directory, you can use that value for the the receiverIdentifier value. This allows the receiver to keep their account number hidden if they are worried about privacy. Not all accounts have alias values, in which case you'd use the account number only.
The Pull request should look a lot like the Push request, with the main difference being the transaction type. In a Pull request, the receiverIdentifier tells the system which account gets the payment instruction and will be debited if completed. An account must be configured to allow pull transactions to perform a debit. In addition, all debits must be approved by the receiver before the transaction can be completed.
For XPay API calls made by Arix, the fields vary somewhat from those in the sample request below. See the XPay validation guidelines for lending﻿ for more details.
