The Consumer Data Right and OpenBanking

Oct 13, 2025 by pynkocean.com 76 views

Introduction

In the world of banking, access to one's own financial data has long been a contentious issue. The traditional method of screen scraping, where a third-party application extracts data from a bank's website, has been widely criticized for its lack of security and reliability. However, with the advent of OpenBanking, a government-mandated interoperability standard for the banking sector, the landscape is changing. In this article, we will delve into the world of OpenBanking API access in Python, specifically focusing on the uBanking API.

The Consumer Data Right and OpenBanking

In Australia, the Consumer Data Right (CDR) is a government-mandated interoperability standard for the banking sector. Also known as OpenBanking, the CDR ensures that banks expose APIs that allow safe access to one's transactions history and account data without relying on hacky methods like screen scraping. The idea behind OpenBanking is to provide customers with greater control over their financial data, allowing them to access and share it securely.

The Challenges of Accessing Financial Data

While the CDR and OpenBanking aim to provide a secure and reliable way to access financial data, the reality is that it can be challenging to get access to one's own transactions without going through an "approved data broker" that charges a premium for it. For example, Basiq, a popular data broker, charges a fee for accessing financial data, while free apps like Frollo have limited export support. This can be frustrating for customers who want to access their financial data without incurring additional costs.

The uBanking API: A Game-Changer

Fortunately, a genius has reverse-engineered the internal uBank API from examining the API requests the frontend makes, and has exposed it as a Python-consumable API with Passkey authentication support. This means that uBank customers can now access their financial data securely and reliably, without relying on third-party data brokers or limited export support apps.

The Power of Python Descriptors

As an aside, the API mentions Python "descriptors", which is an intriguing functionality worth exploring. Descriptors are a feature in Python that allows developers to implement custom attribute access and modification behavior. In the context of the uBanking API, descriptors can be used to implement custom authentication and authorization logic, providing an additional layer of security and flexibility.

Getting Started with the uBanking API

If you're interested in exploring the uBanking API, you can find the code on GitHub at https://github.com/eidorb/ubank. The API is designed to be easy to use, with a simple and intuitive interface. To get started, you'll need to install the required dependencies, including the requests library, and then authenticate with the API using your uBank credentials.

Conclusion

In conclusion, the uBanking API is a game-changer for uBank customers who want to access their financial data securely and reliably. With its Python-consumable API and Passkey authentication support, the uBanking API provides a powerful and flexible way to access one's financial data. Whether you're a developer looking to build a custom application or a customer looking to access your financial data, the uBanking API is definitely worth exploring.

Code Snippets

Here are some code snippets to get you started with the uBanking API:

import requests

# Set your uBank credentials
username = "your_username"
password = "your_password"

# Authenticate with the API
response = requests.post("https://api.ubank.com/auth", json={"username": username, "password": password})

# Get your account balance
response = requests.get("https://api.ubank.com/accounts/your_account_id/balance")

# Print the account balance
print(response.json()["balance"])

Note: This is just a basic example to get you started. You'll need to modify the code to suit your specific use case and requirements.

Future Developments

The uBanking API is still in its early stages, and there are many exciting developments on the horizon. Some potential future developments include:

Improved authentication and authorization logic
Support for additional financial data, such as transactions and statements
Integration with other banking APIs and services
Development of custom applications and tools using the uBanking API
