Payment Gateways
With Craft Commerce, payments gateways are provided by Craft CMS plugins.
To create a payment gateway you must install the appropriate plugin, navigate to Commerce → Settings → Gateways, and set up the appropriate gateway. For more detailed instructions, see each plugin’s README.md file.
Payment gateways generally fit in one of two categories:
- External or offsite gateways.
- Merchant-hosted or onsite gateways.
Merchant-hosted gateways collect the customer’s credit card details directly on your site, but have much stricter requirements such as an SSL certificate for your server. You will also be subject to much more rigorous security requirements under the PCI DSS (Payment Card Industry Data Security Standard). These security requirements are your responsibility, but some gateways allow payment card tokenization.

# Dummy Gateway
After installation, Craft Commerce will install some demo products and a basic config along with a Dummy payment gateway for testing.
This dummy gateway driver is only for testing with placeholder credit card numbers. A valid card number ending in an even digit will get a successful response. If the last digit is an odd number, the driver will return a generic failure response:
4242424242424242 ✓ Success
4444333322221111 ✗ Failure
# Manual Gateway
The manual payment gateway is a special gateway that does not communicate with any third party.
You should use the manual payment gateway to accept checks or bank deposits: it simply authorizes all payments allowing the order to proceed. Once the payment is received, the payment can be manually marked as captured in the control panel.
# Other gateway specifics
Before using a plugin-provided gateway, consult the plugin’s readme for specifics pertaining to the gateway.
# Adding additional gateways
Additional payment gateways can be added to Commerce with relatively little work. The first-party gateway plugins, with the exception of Stripe, use the Omnipay payment library (opens new window) and can be used as point of reference when creating your own.
# Storing config outside of the database
If you do not wish to store your payment gateway config information in the database (which could include secret API keys), you can override the values of a payment method’s setting via the commerce-gateways.php config file. Use the payment gateway’s handle as the key to the config for that payment method.
The gateway must be set up in the control panel in order to reference its handle in the config file.
return [
'myStripeGateway' => [
'apiKey' => getenv('STRIPE_API_KEY'),
],
];
# Payment sources
Craft Commerce supports storing payment sources for select gateways. Storing a payment source allows for a more streamlined shopping experience for your customers.
The following first-party provided gateways support payment sources:
- Stripe
- PayPal REST
- eWAY Rapid
# 3D Secure payments
3D Secure payments add another authentication step for payments. If a payment has been completed using 3D Secure authentication, the liability for fraudulent charges is shifted from the merchant to the card issuer. Support for this feature depends on the gateway used and its settings.
# Partial refunds
All first-party provided gateways support partial refunds as of Commerce 2.0.
