Fund API
Click to copy

This API is used for the classic integration. If you are just starting your implementation, refer to our new integration guide instead.

The Fund API provides endpoints for managing the funds in the accounts on your platform. These management operations include, for example, the transfer of funds from one account to another, the payout of funds to an account holder, and the retrieval of balances in an account.

For more information, refer to our documentation.


Your Adyen contact will provide your API credential and an API key. To connect to the API, add an X-API-Key header with the API key as the value, for example:

-H "Content-Type: application/json" \

Alternatively, you can use the username and password to connect to the API using basic authentication. For example:

-H "Content-Type: application/json" \

When going live, you need to generate new web service user credentials to access the live endpoints.


The Fund API supports versioning using a version suffix in the endpoint URL. This suffix has the following format: "vXX", where XX is the version number.

For example:
Get the balances of an account holder
Get a list of transactions
Send a direct debit request
Pay out from an account to the account holder
Refund a funds transfer
Refund all transactions of an account since the most recent payout
Designate a beneficiary account and transfer the benefactor's current balance
Transfer funds between platform accounts
