Using this plugin you can work in your WooCommerce store with almost all Spanish banks like: Santander, BBVA, La Caixa, ING, etc. using the new security method based on SHA-256 (the only one valid from 23th November 2015).
The plugin incorporates a configuration form. You will only need to fill some data provided by the bank. This form is self-validated so this is easier than others and there will be no errors.
This gateway also is able to mark the order as completed or processing, as you like, choosing how it should work, we can choose between:
* Leave always processing
