This module is used to connect your django application to the payment
provider Adyen using the `“Web
Components” <https://docs.adyen.com/online-payments/web-components>`__
and `“Web
Drop-in” <https://docs.adyen.com/online-payments/web-drop-in>`__

This is only tested on a postgres database.

Supported Ayden Payments
------------------------

-  **Alipay** - adyen name: ``alipay``
-  **Bancontact** card - adyen name: ``bcmc``, uses brands
-  **(Debit/Credit) Card** - adyen name: ``schema``, uses brands
-  **Finnish E-Banking** - adyen name: ``ebanking_FI``
-  **iDEAL** - adyen name: ``ideal``
-  **SEPA Bank Transfer** - adyen name: ``bankTransfer_IBAN``
-  **SEPA Direct Debit** - adyen name: ``sepadirectdebit``

Issuers & Brands
~~~~~~~~~~~~~~~~

Both issuers and brands are used for ``AdyenIssuer`` objects for
different payment options. Some will use one ``adyen_id`` for one issuer
while some others will use a list of ``adyen_id``\ s for allowed brands.

Installation
------------

Install with pip

.. code:: shell

   pip install djadyen

Add *‘djadyen’* to the installed apps

.. code:: python

   # settings.py

   INSTALLED_APPS = [
       ...
       'djadyen',
       ...
   ]

Add the Adyen notifications urls (This is not required). These url will
save all the notifications to the database. You need to make an
implementation to handle the notifications

.. code:: python

   # urls.py

   urlpatterns = [
       ...
       url(r'^adyen/notifications/', include('djadyen.notifications.urls', namespace='adyen-notifications')),
       ...
   ]

.. code:: python

   # models.py
   from djadyen.models import AdyenOrder

   class CustomOrder(AdyenOrder):
       def get_price_in_cents(self):
           """
           :return int Return the price in cents for this order.
           """
           raise NotImplementedError

       def get_return_url(self):
           raise NotImplementedError(
               "Please override 'get_return_url' on the '{model_name}'".format(
                   model_name=self.\_meta.object_name
               )
           )

Usage
-----

Management command
~~~~~~~~~~~~~~~~~~

There is a management command that will sync the payment methods for
you. This can be used if you want the users to select a payment
method/issuer on your own site.

``manage.py sync_payment_methods``

There is a command that will call the function ``process_notification``
to handle notifications. This can be added to a crontab.

``manage.py adyen_maintenance``

Required settings
~~~~~~~~~~~~~~~~~

-  ``DJADYEN_SERVER_KEY`` *This is the server key. This should be a
   secret string.*
-  ``DJADYEN_CLIENT_KEY`` *This is the client key. This key will be used
   in the components in the frontend.*
-  ``DJADYEN_MERCHANT_ACCOUNT`` *This is the merchant accont that is
   used in Adyen.*
-  ``DJADYEN_ORDER_MODELS`` *A list of models that are used to store
   Orders (Inherit from AdyenOrder). The models should be strings in the
   . form*
-  ``DJADYEN_NOTIFICATION_KEY`` *The key to verify the notifications are
   from adyen*

Optional settings
~~~~~~~~~~~~~~~~~

-  ``DJADYEN_CURRENCYCODE`` *(default=‘EUR’) This can be set to any
   other currency Adyen supports.*
-  ``DJADYEN_ENVIRONMENT`` *(default=‘test’) This can be ‘test’ or
   ‘live’.*
-  ``DJADYEN_APPNAME`` *(default=‘Djadyen Payment’) This is the name
   that will be send along with the payment.*
-  ``DJADYEN_REFETCH_OLD_STATUS`` *(default=False) This is so you will
   always have the latest saved status. This will cause an extra db
   query!*
-  ``DJADYEN_HANDLE_NOTIFICATION_MINUTES_AGO`` *(default=15) This
   defaults to 15 minutes. You can change the value to make this shorter
   or longer depending on the need.*

DJADYEN_STYLES
^^^^^^^^^^^^^^

(Optional) Customize the appearance of Adyen payment components.

This setting allows you to configure the styling of Adyen Web Components
by providing style definitions that are passed to the payment component
configuration. This enables you to customize colors, fonts, and other
visual properties of the payment form fields.

**Example:**

.. code:: python

   # settings.py
   DJADYEN_STYLES = {
       'base': {
           'color': '#000000',
           'fontSize': '16px',
           'fontFamily': 'Arial, sans-serif',
       },
       'placeholder': {
           'color': '#999999',
       },
       'error': {
           'color': '#ff0000',
       },
       'validated': {
           'color': '#00ff00',
       }
   }

**How it works:**

The styles object is passed to the Adyen payment component
configuration, allowing you to customize the appearance of input fields.
The configuration supports several style categories:

-  ``base``: Default styling for form input fields
-  ``placeholder``: Styling for placeholder text
-  ``error``: Styling for fields in an error state
-  ``validated``: Styling for successfully validated fields

**Available style properties:**

Within each category, you can use properties like: - ``color``: Text
color - ``fontSize``: Font size (e.g., ‘16px’, ‘1rem’) - ``fontFamily``:
Font family - ``fontWeight``: Font weight - ``lineHeight``: Line height
- And other CSS-like properties supported by Adyen components

For a complete list of available styling options and examples, refer to
the `Adyen Card Component Styling
Documentation <https://docs.adyen.com/payment-methods/cards/custom-card-integration/#styling>`__.

**Note:** These styles apply specifically to Adyen’s secured fields
(like card number, CVV, expiry date). For styling the container or other
elements, use regular CSS in your stylesheets.

If ``DJADYEN_STYLES`` is not set, Adyen’s default styling will be used.

Order object
~~~~~~~~~~~~

There is an abstract order in this package. This will save you some time
on creating an order for adyen. There are some features on the order
that will make it easier to integrate your order with this package.

The added fields are:

-  ``status`` *This is the status of the object. This will be changed by
   adyen.*
-  ``created_at`` *This field is used for when the order is created.*
-  ``reference`` *This field is a communication field. It is not used
   outside the communication. This will be set by uuid4, but can be
   overwritten.*
-  ``psp_reference`` *This field is the reference from Adyen. With this
   field you are able to search in the Adyen inderface.*
-  ``payment_option`` *This is the Adyen payment option from this
   package.*
-  ``issuer`` *This is the Adyen issuer from this package.*

You should implement the following methods

-  ``get_price_in_cents`` *Return the price to be paid for this order*
-  ``process_authorized_notification`` *Process a ‘authorized’
   notification which adyen has sent*
-  ``process_notification`` *Process the notification, if you are using
   the adyen-maintenance management command*

AdyenPaymentView
~~~~~~~~~~~~~~~~

This view is used to show the payment page.

This page can be customized in 2 ways.

1. overwrite the template (``adyen/pay.html``)
2. Overwrite the view and changing the ``template_name``

.. code:: python

   from djadyen.views import AdyenPaymentView


   class PaymentView(AdyenPaymentView):
       template_name = "my_adyen/pay.html"  # Optional

Adyen requires a language locale i.e. ``nl-NL`` or ``en-US`` instead of
``nl`` or ``en``. If Django’s uses language codes, ``adyen_language``
should be converted in the view context similarly to this:

.. code:: python

    ADYEN_LANGUAGES = {
        "nl": "nl-NL",
        "en": "en-US",
    }

    class PaymentView(AdyenPaymentView):
        ...

        def get_locale(self):
            return ADYEN_LANGUAGES[self.request.LANGUAGE_CODE]


AdyenResponseView
~~~~~~~~~~~~~~~~~

Adyen also creates a response. This will help you with catching the
response. This view will check if the response from Adyen is valid. It
will also provide some useful functions so you don’t have to overwrite
anything.

In this example the order is automatically fetched from the reference that
is passed in the merchantReference. It will also set the order in the
self object for easy access. In the done function the order is saved and
the template will be rendered.

.. code:: python

   from djadyen.views import AdyenResponseView
   from djadyen.choices import Status


   class ConfirmationView(AdyenResponseView):
       template_name = 'my_project/confirmation.html'
       model = Order

       def handle_authorised(self):
           self.order.status = Status.Authorised
           return self.done()

AdyenAdvancedPaymentView
~~~~~~~~~~~~~~~~~~~~~~~~

Similar to the ``AdyenPaymentView`` but uses the advanced checkout from ``adyen-web``.
This allows for more payment methods and allows for the new Giving donation component.
The advanced view can handle adyen responses and does not need the ``AdyenResponseView``.

The view should implement the ``adyen_advanced_payment_component`` template tag in the template.
The ``AdyenAdvancedPaymentView`` also needs to override ``get_locale`` to get the correct locale if it is not already.


.. code:: python

    from djadyen.views import AdyenAdvancedPaymentView

    class AdvancedPaymentView(AdyenAdvancedPaymentView):
        template_name = 'my_project/confirmation.html'
        model = Order


Adyen notifications
===================

Setup the standard notifications in Adyen. These will comunicate about
the payments if they were succesful or not. This is **very important**
because the notifications will be needed when a payment is redirected
with a pending payment.

The notifications will be stored in the database. You need to write the
handling of the notifications yourself or use the ``adyen_maintenance``
command.
