How to programmatically retrieve configuration of the specific payment module?
I tried
$settings = rules_config_load('commerce_payment_MODULE_NAME');
It returns very basic info (name, ID etc) and empty "settings" array.
Cant also get it directly from DB .
It is stored in serialized array that can not be fully processed with the unserialize() function.
I'm using this:
$payment = commerce_payment_method_instance_load('foo|commerce_payment_foo');
where foo is the payment method string identifier.
The resulting array contains the 'settings' index, with the data saved in the settings form.
In other words foo|commerce_payment_foo is instance id which consist method_id|rule_name.
The method_id can be found by executing commerce_payment_methods() and rule_name can be found in URL when editing Payment action (at /admin/commerce/config/payment-methods).
