Form Processing & Audit Automation

A robust form ingestion and processing microservice that validates user-submitted form data, sanitizes inputs, flags anomalies, and dispatches verified webhooks.

---

Key Features

• Dynamic: form schema validation and sanitization
• Anomaly: and fraud detection identifying spam or fraudulent submissions
• Automated: verification email and confirmation receipt generator
• Downstream: webhook dispatcher sending sanitized payloads to target systems
• Persistent: audit trail logging all submissions

Getting Started

Prerequisites

• Python 3.10+ (Python 3.12 recommended)
• pip package manager

Installation

1. Clone the repository:

   git clone https://github.com/erhatechnologiesai/form-processing-automation.git
   cd form-processing-automation

2. Create and activate a virtual environment:

   python -m venv venv
   # On Windows:
   venv\Scripts\activate
   # On macOS/Linux:
   source venv/bin/activate

3. Install dependencies:

   pip install -r requirements.txt

4. Configure environment variables:

   cp .env.example .env

Running the Application

Start the local development server with auto-reload:

python -m uvicorn app.api:app --reload --host 0.0.0.0 --port 8000

Once running, interactive documentation is accessible at:

• Swagger UI: http://127.0.0.1:8000/docs
• ReDoc: http://127.0.0.1:8000/redoc

API Endpoints

Method	Endpoint	Description
POST	/submit-form	Ingest, validate, sanitize, and dispatch form submission

Example Request

curl -X POST http://127.0.0.1:8000/submit-form -H "Content-Type: application/json" -d '{"form_id": "contact_sales", "fields": {"name": "Alice Smith", "email": "alice@company.com", "message": "Inquiring about enterprise tier"}}'

---

Running Tests

Execute the automated test suite:

python -m unittest tests/test_form_processing.py

Or using pytest:

pytest tests/

All test cases are self-contained and run offline without requiring third-party API credentials.

---

Security & Best Practices

• Zero Credential Leakage: API tokens and secrets are loaded exclusively via environment variables and excluded by .gitignore.
• Strict Validation: All incoming request payloads are strictly validated using Pydantic schemas.
• Fail-Safe Fallbacks: Deterministic offline engines guarantee application continuity even during external provider outages.
