Process online payments

Learn how to split transactions with your users.

Before your users can start accepting payments from their customers, you need to build an Adyen online payments integration and a checkout UI, and configure the payment methods for the merchant accounts or stores in your platform.

To make sure that the pay-in, settlement, and payout processes run smoothly, you must book the incoming funds and fees to the correct balance accounts. This means that in each individual payment, capture, and refund request that you send on behalf of your users, you have to include information on how to split the funds between your user's balance accounts and your platform's liable balance account.

Splitting transactions

Transactions processed through Adyen must be split between the balance accounts in your platform: your liable balance account and your users' balance accounts.

You can split funds into any number of balance accounts in your platform. For example, when a customer pays, you can split the funds into multiple parts:

  • The sale amount, which goes to your user's balance account.
  • Your platform's commission, which goes to your platform's liable account.
  • The transaction fees, which can be charged to your user's balance account.
  • The remainder after currency conversion, which can be booked to your user's balance account.

You must send the split instructions with every payment, capture, or refund request. If you do not provide any split information, the whole transaction is booked to your platform's liable balance account, including all associated fees.
