Commerce v1 Developer Payment Gateways GatewayHelper

The GatewayHelper (\modmore\Commerce\Gateways\Helpers\GatewayHelper) is a static helper class that you can use inside payment gateways.

getNotifyURL

Use GatewayHelper::getNotifyURL(comTransaction $transaction) to get a normalised webhook notification URL.

This will return a fully qualified URL to assets/components/commerce/notify.php with the transaction ID, in such a way that Commerce can automatically route the webhook request to the right transaction/gateway instance.

getSharedNotifyURL

Use GatewayHelper::getSharedNotifyURL(\comPaymentMethod $method) to get a normalised webhook notification URL for gateways that do not implement transaction-specific notification/webhook URLs.

This will return a fully qualified URL to assets/components/commerce/notify.php with the payment method ID. When such a request is received, and

getReturnUrl

Use GatewayHelper::getReturnURL(comTransaction $transaction) to get the URL to redirect the customer to in the case of an off-site redirect payment. This is a fully qualified URL to the (context-specific) checkout page, including the transaction ID.

getCancelUrl

Use GatewayHelper::getCancelURL(comTransaction $transaction) to get the URL to redirect the customer to in the case of an off-site redirect payment that was cancelled. This is a fully qualified URL to the (context-specific) checkout page, including the transaction ID and the cancel_transaction parameter.

getDescription

Use GatewayHelper::getDescription(comOrder $order) to return the payment description/descriptor that can be shown to the customer or included on a payment reference. This is a translated (lexicon) string in the format Order {id} at {site_name}.

The description will automatically use either the order ID or the reference if it is already set, and a context-specific site name.

normalizeNames

Use normalizeNames(&$firstName, &$lastName, &$fullName) to normalize the usage of first/last/full names. Commerce supports both split name fields and fullname fields for addresses, and gateways sometimes require different values.

The normalizeNames method updates the referenced variables:

  • If $firstName and $lastName are empty, but $fullName is not, $firstName is set to the first space-separated word in $fullName and $lastName is filled with the remainder.
  • If $fullName is empty, but $firstName and $lastName are not, $fullName is set to $firstName $lastName.
