Virtual Bank Web Application and API

Introduction

Welcome to the Virtual Bank project! This web application and API were created to provide developers with a platform for simulating banking transactions. Whether you're testing e-commerce websites or exploring payment integrations, our project allows you to experiment without using real bank APIs. Built on Django, it offers a range of functionalities tailored for transaction simulation. if you want to delve deeper into the details of this project, feel free to visit this blog post authored by Adeniji Olajide.

    cd api/
    python manage.py runserver

    Create User:

    curl -X POST http://localhost:8000/api/users/create/ -H 'Content-Type: application/json;' -d '{
        "username": "max_miller",
        "password": "maxm1234",
