+# [Adyen Checkout](https://docs.adyen.com/checkout) integration demo
+
+This repository includes examples of PCI-compliant UI integrations for online payments with Adyen. Within this demo app, we've created a simplified version of an e-commerce website, complete with commented code to highlight key features and concepts of Adyen's API. Check out the underlying code to see how you can integrate Adyen to give your shoppers the option to pay with their preferred payment methods, all in a seamless checkout experience.
+
+![Card Checkout Demo](app/static/img/cardcheckout.gif)
+
+## Supported Integrations
+
+**Python with Flask** demos of the following client-side integrations are available in this repository:
+
+- [Drop-in](https://docs.adyen.com/checkout/drop-in-web)
+- [Component](https://docs.adyen.com/checkout/components-web)
+  - ACH
+  - Alipay
+  - Boleto
+  - Card
+  - Dotpay
+  - Giropay
+  - iDEAL
+  - Klarna
+  - PayPal
+  - SEPA Direct Debit
+  - Sofort
+
+Please make sure to [add the above payment methods to your Adyen account](https://docs.adyen.com/payment-methods#add-payment-methods-to-your-account) before testing!
+
+## Requirements
+
+- Python 3.5 or greater
+- Python libraries:
+  - flask
+  - uuid
+  - Adyen v6.0.0 or higher
+
+## Installation
+
+1. Clone this repo
+
+```
+git clone https://github.com/adyen-examples/adyen-python-online-payments.git
+```
+
+2. Run `source ./setup.sh` to:
+   - Create and activate a virtual environment
+   - Download the necessary python dependencies
+
+3. Create a `.env` file with all required configuration 
+
+   - PORT (default 8080)
+   - [API key](https://docs.adyen.com/user-management/how-to-get-the-api-key)
+   - [Client Key](https://docs.adyen.com/user-management/client-side-authentication) 
+   - [Merchant Account](https://docs.adyen.com/account/account-structure)
+   - [HMAC Key](https://docs.adyen.com/development-resources/webhooks/verify-hmac-signatures)
+
+Remember to include `http://localhost:8080` in the list of Allowed Origins
+
+```
+    PORT=8080
+    ADYEN_API_KEY="your_API_key_here"
+    ADYEN_MERCHANT_ACCOUNT="your_merchant_account_here"
+    ADYEN_CLIENT_KEY="your_client_key_here"
+    ADYEN_HMAC_KEY="your_hmac_key_here"
+```
+
+## Usage
+1. Run `./start.sh` to:
+   - Initialize the required environment variables. This step is necessary every time you re-activate your venv
+   - Start Python app    
+ 
+2. Visit [http://localhost:8080](http://localhost:8080) and select an integration type!

+Flask
+=====
+
+Flask is a lightweight `WSGI`_ web application framework. It is designed
+to make getting started quick and easy, with the ability to scale up to
+complex applications. It began as a simple wrapper around `Werkzeug`_
+and `Jinja`_ and has become one of the most popular Python web
+application frameworks.
+
+Flask offers suggestions, but doesn't enforce any dependencies or
+project layout. It is up to the developer to choose the tools and
+libraries they want to use. There are many extensions provided by the
+community that make adding new functionality easy.

+Jinja
+=====
+
+Jinja is a fast, expressive, extensible templating engine. Special
+placeholders in the template allow writing code similar to Python
+syntax. Then the template is passed data to render the final document.
+
+It includes:
+
+-   Template inheritance and inclusion.
+-   Define and import macros within templates.
+-   HTML templates can use autoescaping to prevent XSS from untrusted
+    user input.
+-   A sandboxed environment can safely render untrusted templates.
+-   AsyncIO support for generating templates and calling async
+    functions.
+-   I18N support with Babel.
+-   Templates are compiled to optimized Python code just-in-time and
+    cached, or can be compiled ahead-of-time.
+-   Exceptions point to the correct line in templates to make debugging
+    easier.
+-   Extensible filters, tests, functions, and even syntax.
+
+Jinja's philosophy is that while application logic belongs in Python if
+possible, it shouldn't make the template designer's job difficult by
+restricting functionality too much.
+
+
