Introduction

The automation tackles the challenge of integrating multiple financial services, where some services (like Square and Wise) provide APIs, and others (like Relay and Huntington) require Nodriver-based browser automation. The need for frequent updates due to site changes and the ability to bypass protections on these sites is central to the solution. This automation streamlines the complex and repetitive task of fund movement between these platforms, ensuring both efficiency and accuracy.

Banking Automation with FastAPI and Nodriver

• Automates interactions with both API-enabled and non-API platforms
• Ensures reliable data scraping and automation through Nodriver
• Provides scalability for handling dynamic changes on target websites
• Focuses on seamless integration and reliable execution of financial operations
• Incorporates error handling and frequent updates to bypass site protections

Core Features

Feature	Description

How It Works

Step	Description
Input or Trigger	The system begins operation when an API request is made or a scheduled automation task triggers the process.
Core Logic	Validates the request, checks for required data, and processes the API call or automation task based on the target platform.
Output or Action	Generates a response or triggers a web scraping action, ensuring that funds are moved or data is collected as required.
Other Functionalities	Implements retries for transient errors, real-time logging, and parallel execution for multiple endpoints.
Safety Controls	Includes safeguards such as IP rotation, rate limiting, and CAPTCHA bypass mechanisms to ensure ethical and secure operations.
