Create a SetupIntent with payment_method_types=['us_bank_account'] and the customer ID; the PaymentMethod can be created with manually entered routing and account numbers
Stripe automatically sends a single $0.01 microdeposit with a unique 6-character descriptor code beginning with 'SM' to the provided account
The customer receives the deposit within 1–2 business days and retrieves the descriptor code from their bank statement
The customer submits the descriptor code; call stripe.verifyMicrodepositsForSetup on the client or POST to /v1/setup_intents/:id/verify_microdeposits with descriptor_code server-side
On successful verification, the SetupIntent status moves to 'succeeded' and the PaymentMethod is confirmed as verified
Use the confirmed PaymentMethod for future payments or store it for off-session ACH debits
Known gotchas
Customers have 10 days from microdeposit issuance to complete verification; after 10 days the SetupIntent expires and the process must restart
Stripe now uses a single descriptor-code microdeposit (not two-amount microdeposits) for us_bank_account verification; do not document or expect a two-deposit flow for new integrations
Verification can only be attempted a limited number of times per SetupIntent; after too many incorrect attempts, the SetupIntent is invalidated
