Build your payment form for ACH Direct Debit

When a shopper chooses to pay with ACH Direct Debit, collect the following payment details in your payment form:

Payment details	Example
Bank account number	The US bank account number from which the payment will be debited. Format: numeric. Minimum length: 4 Maximum length: 17 Example: `01234567890123`
Bank routing number	The 9-digit ACH routing number of the account. Alert your shoppers that some banks have different routing numbers for different transfers. Shoppers should not provide their wire transfer routing number. Do not remove any leading zeros. Adyen performs validation to ensure the routing number is genuine. Example: `123456789`
Bank account type	checking or savings
Account owner's name	"John Smith"
Account owner's address	A valid US address (optional field).

We provide an ACH Direct Debit logo which you can use in your payment form. For more information, refer to Downloading logos.

You can also get the required fields from the /paymentMethods response as explained in our API-only integration guide. In your /paymentMethods request, specify:

countryCode: US
amount.currency: USD

The required fields are included in the object with type ach.

Bank account type

Customers can use both checking accounts and savings accounts to make ACH payments. If you do not provide the bankAccountType in your payment request, this defaults to checking account. In cases where the account type defaulted to checking account while the customer provided the account number of a savings account, this mismatch will lead to a chargeback.

To avoid chargebacks, we recommend collecting the bank account type from the customer, and providing it in your payment request.

Make a payment

From your server, make a /payments request, specifying:
- paymentMethod.type: ach
- paymentMethod.bankAccountNumber: the bank account number.
- paymentMethod.bankAccountType: the type of bank account. Allowed values: checking, savings.
- paymentMethod.bankLocationId: the ACH routing number of the account.
- paymentMethod.ownerName: the name on the bank account.
- billingAddress (Optional): the account owner's address information.
The following example shows a /payments request for an ACH Direct Debit payment.
In the /payments response, note the following:
- resultCode: Authorised. This means that the payment has been successfully received by Adyen. However, it may take up to 5 business days to know whether the payment was authorized by the bank. If the payment is successful, it will appear in the Settlement details report. If it fails, you may receive a chargeback.
- pspReference: Our unique reference for the payment.
```

Test and go live

You can test ACH Direct Debit payments as well as chargebacks.

Test the payment flow

Before making live ACH Direct Debit payments, use the following account details to test your integration.

`ownerName`	`bankAccountNumber`	`bankLocationId` (routing number)	`billingAddress` (account owner's address)
Any name	Any correctly formatted account number. Example: 1234567890	011000138 or 121000358	Any correctly formatted US address.

Test the chargeback flow

You can test the chargeback flow by making test payments with an ownerName value that consists of chargeback: followed by an ACH return reason code. For example, chargeback:R01. The other account details to use are the same as when testing payments.
