Migrating from another processor

Stripe works with you and your current payment processor to migrate data into your Stripe account. After the import completes, Stripe provides you with a CSV or JSON Mapping File to help you match the old customer IDs to the imported Stripe object IDs.

To request this option, submit an intake form and select the ACH payment type.

If you choose to migrate yourself, Stripe temporarily allows you to bypass bank account verification. To request this temporary capability, contact Stripe support and include details about how your business:

• Collects authorization from customers
• Verifies customer bank accounts

After Stripe enables this option, process each bank account and create a SetupIntent for each account:

1. Create a new Customer object or retrieve an existing one to associate with this bank account.

curl -X POST https://api.stripe.com/v1/customers \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:"

1. Create and confirm a SetupIntent with your saved bank account details and the date of your customer’s original authorization to debit the account.

curl https://api.stripe.com/v1/setup_intents \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d "payment_method_types[]"=us_bank_account \
  -d customer={{CUSTOMER_ID}} \
  -d confirm=true \
  -d "payment_method_options[us_bank_account][verification_method]"=skip \
  -d "payment_method_data[type]"=us_bank_account \
  -d "payment_method_data[billing_details][name]"={{ACCOUNT_HOLDER_NAME}} \
  -d "payment_method_data[us_bank_account][routing_number]"={{ROUTING_NUMBER}} \
  -d "payment_method_data[us_bank_account][account_number]"={{ACCOUNT_NUMBER}} \
  -d "payment_method_data[us_bank_account][account_holder_type]"=individual \
  -d "mandate_data[customer_acceptance][type]"=offline \
  -d "mandate_data[customer_acceptance][accepted_at]"=1692821946

1. Retrieve and store the PaymentMethod ID from the response to use for future payments. You can also retrieve it by listing all PaymentMethods for the customer.
