Credit Cards
Server-Side Implementation
Creating transactions
Using Transaction: Sale is the simplest way to create a credit card transaction.
You can create a transaction with just an amount and a payment_method_nonce relayed from your client and immediately submit it for settlement.
Collect device data from the client and include the device_data_from_the_client in the transaction.
- Ruby
result = gateway.transaction.sale(
:amount => "10.00",
:payment_method_nonce => nonce_from_the_client,
:device_data => device_data_from_the_client,
:options => {
:submit_for_settlement => true
}
)
if result.success?
# See result.transaction for details
else
# Handle errors
end
If you want to create a new payment method in the Vault upon a successful transaction, use the options.store_in_vault_on_success option. If a customer_id is not included, a new customer will be created.
Card verification
When a payment method is a credit or debit card, you can use card verification to verify that the card data matches a valid, open account before storing or updating it in the Vault.
Braintree strongly recommends verifying all cards before they are stored in your Vault by enabling card verification in the Control Panel.
If you do not want to verify all cards by default, you can run one-time requests using options.verify_card when:
In both cases, the gateway verifies cards by running either a $0 or $1 authorization and then automatically voiding it. If you'd like, you can specify a different options.verification_amount to use for the authorization.
- Ruby
result = gateway.payment_method.create(
:customer_id => "the_customer_id",
:payment_method_nonce => nonce_from_the_client,
:options => {
:verify_card => true,
:verification_merchant_account_id => "the_merchant_account_id",
:verification_amount => "2.00",
}
)
Verification results
If verification was successful, the result will contain a CreditCard response object, which will contain a CreditCardVerification response object.
- Ruby
result = gateway.payment_method.create(
:customer_id => "the_customer_id",
:payment_method_nonce => nonce_from_the_client,
:options => {
:verify_card => true
}
)
if result.success?
verification = result.payment_method.verification
end
Otherwise, you'll receive a CreditCardVerification response object directly on a Customer or PaymentMethod result. This occurs if:
- A verification ran, and
- It was returned with a status of processor_declined or gateway_rejected
Reasons for unsuccessful verification results
You can check the processor_response_code and processor_response_text for the specific reason that a verification was processor_declined
- Ruby
result = gateway.payment_method.create(
:customer_id => "the_customer_id",
:payment_method_nonce => nonce_from_the_client,
:options => {
:verify_card => true
}
)
result.success?
#=> false
verification = result.credit_card_verification
verification.status
#=> "processor_declined"
verification.processor_response_type
#=> "soft_declined"
verification.processor_response_code
#=> "2000"
verification.processor_response_text
#=> "Do Not Honor"
If the status is gateway_rejected, you can check the gateway_rejection_reason for the specific reason. Learn more about gateway rejections.
- Ruby
result.success?
#=> false
verification = result.credit_card_verification
verification.status
#=> "gateway_rejected"
verification.gateway_rejection_reason
#=> "cvv"
Verifications on sub-merchant accounts
For those using Braintree Marketplace, verifications can't be done using sub-merchant accounts. See Braintree Marketplace Verifications for more details.
