Config Settings

In addition to the settings in Commerce → Settings, the config items below can be saved in a config/commerce.php file using the same format as Craft’s general config settings in config/general.php.

For example, if you wanted to change the inactive carts duration in dev environments but not on staging or production, you could do this:

return [
    // Global settings
    '*' => [
        // ...
    ],

    // Dev environment settings
    'dev' => [
        'purgeInactiveCartsDuration' => 'P1D',
        // ...
    ],

    // Staging environment settings
    'staging' => [
        // ...
    ],

    // Production environment settings
    'production' => [
        // ...
    ],
];

You can access the Commerce general settings model (opens new window) in your templates:

{% set settings = craft.commerce.settings %}

# Payments

# `allowPartialPaymentOnCheckout`

Allowed types: boolean (opens new window)
Default value: false
Defined by: Settings::$allowPartialPaymentOnCheckout (opens new window)

Whether partial payment can be made from the front end when the gateway allows them.

The false default does not allow partial payments on the front end.

# `gatewayPostRedirectTemplate`

Allowed types: string (opens new window)
Default value: ''
Defined by: Settings::$gatewayPostRedirectTemplate (opens new window)

The path to the template that should be used to perform POST requests to offsite payment gateways.

The template must contain a form that posts to the URL supplied by the actionUrl variable and outputs all hidden inputs with the inputs variable.

<!DOCTYPE html>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>Redirecting...</title>
</head>
<body onload="document.forms[0].submit();">
<form action="{{ actionUrl }}" method="post">
  <p>Redirecting to payment page...</p>
  <p>
    {{ inputs|raw }}
    <button type="submit">Continue</button>
  </p>
</form>
</body>
</html>

Since this template is simply used for redirecting, it only appears for a few seconds, so we suggest making it load fast with minimal images and inline styles to reduce HTTP requests.

If empty (default), each gateway will decide how to handle after-payment redirects.
