This is an Adyen app for Django. It provides an easy way to integrate the Adyen payment system into a Django project. Regular, oneclick and recurring payments are supported. All communication to and from Adyen is logged.

The project is however far from perfect and it hasn't been used in production yet. There might be bugs, so be aware if you want to use this. Also, if you use this app, you should still know how Adyen works, the app just simplifies the process. However, occasionally the implementation documentation will explain what happens under the hood. Sometimes it will refer to the Adyen documentation for futher reading.


As said before, the project is far from perfect. Not all Adyen features are implemented and the system hasn't even been tested thoroughly in production. Since Adyen implementation is not straightforward and Adyen is a quite popular payment service provider and Django is a popular framework, I hope people will find use for it.

If you want to contribute, you're very welcome. Contact me for any questions.


You can install Adyengo with pip:

pip install adyengo



To start out you should add some settings to Django's settings file (by default in myapp/ All settings should be in a dict ADYENGO, for example:

    'A_SETTING': 'A value',
    'ANOTHER_SETTING': 'Another value'

Required settings

  • MERCHANT_ACCOUNT - Your Adyen merchant account.
  • HMAC_KEY - The HMAC key used to validate the communication with Adyen.
  • NOTIFICATION_HMAC_KEY - The HMAC key used to validate notifications from Adyen.
  • MODE - Use test to use the Adyen test environment or live to use the live environment. Default to test.

Required for Recurring Payments

  • API_USERNAME - The username for the Adyen API.
  • API_PASSWORD - The password for the Adyen API.

Optional settings

  • DEFAULT_SKIN_CODE - The default skin code. Can always be overwritten.
  • DEFAULT_PAGE_TYPE - The default page type for an Adyen HPP (Hosted Payment Pages) payment.
  • DEFAULT_CURRENCY_CODE - The default currency code. Can always be overwritten.
  • DEFAULT_SHOPPER_LOCALE - The default shopper locale. If it's not set, the system expects that the skin code will be provided when creating the session.
  • DEFAULT_RES_URL - The default URL the user gets redirected to after an Adyen HPP (Hosted Payment Pages) payment.


There are two ways to do a payment through Adyen. One is to forward the customer to the Adyen Hosted Payment Pages (HPP) and the other is to do a Recurring Payment through Adyen's API.

Adyengo reflects Adyen's interface in regular Django models and managers. The main model to setup a payment is the Session model. So you create a payment by creating an instance of the Session model.

The Session model

Most of the fields in the Session model reflect a field in the Adyen interface. The only difference is that Adyen uses camelCase and Adyengo uses under_scores. So a field in the Adyen interface like merchantReference will become merchant_reference in Adyengo. We will refer to these fields as "Adyen specific fields", other fields we'll call "Adyengo specific fields". When a field in the Session model is an Adyen specific field it will be pointed out. In this case you can get more information about the field in the Adyen Integration Manual.

Besides the Adyen specific fields, the Session model has some Adyengo specific fields for internal logic. The most important one is the session_type field. This field decides what kind of payment the session represents.

The choices for this field are defined in the which you can import using from adyengo import constants. Then you can choose one of the following:

  • constants.SESSION_TYPE_HPP_REGULAR - For a regular payment.
  • constants.SESSION_TYPE_HPP_RECURRING - To setup a recurring contract, or to do a "oneclick" recurring payment.
  • constants.SESSION_TYPE_API_RECURRING - For a recurring payment.

Now let's set up a Regular payment so you get a feeling of how it works.

Regular Payment


To set up a regular payment, you should set the session_type field to constants.SESSION_TYPE_HPP_REGULAR and provide the following Adyen specific fields:

  • merchant_reference - Unique id for the session.
  • payment_amount - Amount for the payment in cents.
Optional fields
  • currency_code - The currency code for the currency the amount is in. Choices are listed in the constants starting with CURRENCY_CODE_, for example CURRENCY_CODE_EUR for Euro. Only required if you didn't set DEFAULT_CURRENCY_CODE.
  • skin_code - The skin code. If you set a default skin code using the DEFAULT_SKIN_CODE settings, you can exclude this field. If you provide it anyway, it will overwrite the default skin code.
  • ship_before_date - The date the product should be shipped, provide as a Python date object. This defaults to 24 hours from now, which is a good default for online services.
  • session_validity - The date the session expires, provide as a Python date object.
  • shopper_reference - Unique id for the customer.
  • shopper_email - The customer's email address.

See the Adyen documentation for more information about the fields.

Adyengo fields

There's one Adyengo specific field you should provide, page_type. This field decides to what kind of page the user gets forwarded. The choices are defined in the constants:

  • constants.PAGE_TYPE_MULTIPLE - For a multiple pages flow.
  • constants.PAGE_TYPE_SINGLE - For a more modern single page app.
  • constants.PAGE_TYPE_SKIP - To skip the page flow. For this choice, precicely one allowed payment method should be provided. We'll describe later how to do that.

When you've set up the Session model, you can save() it. This will automatically turn into a log for you which you can consult in the Django Admin.


To forward the user to Adyen, you should have the session set up and put the parameters in hidden form fields on the page you want to forward the user. You can then either have the user forward himself by clicking a submit button, or automatically forward the user by submitting the form with JavaScript.

To get the parameters for the form, use the params() method on the Session model. To get the url the form should post to, use the url() method.


from django.shortcuts import render
from django.utils import timezone
from adyengo.models import Session
from adyengo import constants

def forward_to_adyen(request):

    s = Session(

    url = s.url()
    params = s.params()

    return render(request, 'forward.html', {
        'url': url,
        'params': params


<form id="adyengo-form" method="POST" action="{{ url }}">
    {% for var, value in params.items %}
        <input type="hidden" name="{{ var }}" value="{{ value }}" />
    {% endfor %}

    // automatically submit the form

This readme isn't finished yet. The code however is usable, so don't hesitate to try it out, and update the readme!

Adyengo Test pages

Adyengo has some test pages, which makes it easy to test different kind of requests to Adyen. You can enable them by adding them to your main

from django.conf import settings
import adyengo

urlpatterns = [
    # Here your regular urlpatterns

if settings.DEBUG:
    urlpatterns += [
        url(r'^adyengo-test/', include(
