Save details for future payments with ACH Direct Debit

Create a Customer object when your user creates an account with your business, or retrieve an existing Customer associated with this user. Associating the ID of the Customer object with your own internal representation of a customer enables you to retrieve and use the stored payment method details later. Include an email address on the Customer to enable Financial Connections’ return user optimization.

By default, collecting bank account payment information uses Financial Connections to instantly verify your customer’s account, with a fallback option of manual account number entry and microdeposit verification. See the Financial Connections docs to learn how to configure Financial Connections and access additional account data to optimize your ACH integration. For example, you can use Financial Connections to check an account’s balance before initiating the ACH payment.

During the Checkout session, the customer sees a dialog that gives them the option to use instant verification or provide bank account details for microdeposit verification.

If the customer opts for microdeposit verification, Stripe automatically sends two small deposits to the provided bank account. These deposits can take 1-2 business days to appear on the customer’s online bank statement. When the deposits arrive, the customer receives an email with a link to confirm these amounts and verify the bank account with Stripe. After verification completes, the payment begins processing.

Learn how to test scenarios with instant verifications using Financial Connections.

Send transaction emails in a sandbox

After you collect the bank account details and accept a mandate, send the mandate confirmation and microdeposit verification emails in a sandbox. To do this, provide an email in the payment_method_data.billing_details[email] field in the form of {any-prefix}+test_email@{any_domain} when you collect the payment method details.

Test account numbers

Stripe provides several test account numbers and corresponding tokens you can use to make sure your integration for manually-entered bank accounts is ready for production.

Before test transactions can complete, you need to verify all test accounts that automatically succeed or fail the payment. To do so, use the test microdeposit amounts or descriptor codes below.

Test microdeposit amounts and descriptor codes

To mimic different scenarios, use these microdeposit amounts or 0.01 descriptor code values.

Test settlement behavior

Test transactions settle instantly and are added to your available test balance. This behavior differs from livemode, where transactions can take multiple days to settle in your available balance.

After completing the Checkout Session, you can collect the PaymentMethod ID. You can use these PaymentMethod IDs to initiate future payments without having to prompt the customer for their bank account a second time.

When creating a PaymentIntent, provide the payment_method and customer IDs to charge your customer using their saved bank account information.
