# SampleApp_Dimensions_Python

A simple Flask application that demonstrates integration with QuickBooks Online API to fetch dimensions and attach those dimensions to invoices. 

## App features

- OAuth 2.0 authentication with QuickBooks Online
- Fetch dimensions from QuickBooks
- Attach dimensions to invoices
- Dimension tracking and management

## Prerequisites

- Python 3.12.7 or higher
- QuickBooks Developer account with OAuth 2.0 credentials
- Quickbooks company with IES subscription
- Dimensions scope enabled for your sample app

## Setup Instructions

1. **Clone the Repository**
   ```bash
   git clone 
   cd SampleApp_Dimensions_Python
   ```

2. **Create Virtual Environment**
   ```bash
   python3 -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   ```

3. **Install Dependencies**
   ```bash
   pip3 install -r FlaskApp/requirements.txt
   ```

4.**Set environment variables**
Create a `.env` file in the root directory of the project with your QuickBooks credentials:
Update the environment variables with your app credentials(Note:In case the .env file doesn't pick your app credentials, you can directly update the values in the codebase at config.py):

```
QB_CLIENT_ID=your_client_id
QB_CLIENT_SECRET=your_client_secret
QB_REDIRECT_URI=your_redirect_uri  # e.g., https://your-ngrok-url.ngrok-free.app/callback
QB_ENVIRONMENT=sandbox # or production
```
## Configure your QuickBooks app

1. Go to Intuit Developer Portal
2. Create a new app or use an existing one
3. Enable Dimensions and Accounting API scopes
4. Add your redirect URI (e.g., https://your-ngrok-url.ngrok-free.app/callback)

## Start ngrok

```bash
ngrok http 5002
```

## Running the Application

1. **Start the Flask Server**
   ```bash
   cd FlaskApp
   python3 app.py
   ```
2. **Access the Application**
   Access the application at `http://localhost:5002`

## Usage Guide

### Authentication

## Security Notes

- Never commit your `.env` file to version control
- Keep your QuickBooks credentials secure
- Use environment variables for all sensitive information
- The `.env` file is automatically ignored by Git

## Troubleshooting

1. **Authentication Issues**
   - Ensure your OAuth credentials are correct in the `.env` file
   - Check that the redirect URI matches your QuickBooks app settings
   - Verify admin is connecting to Quickbooks account

2. **Environment Setup Issues**
   - Make sure the `.env` file exists and contains all required variables
   - Verify that environment variables are being loaded correctly
   - Check that the virtual environment is activated

3. **API Errors**
   - Check the application logs for detailed error messages
   - Verify your QuickBooks subscription includes API access
   - Ensure you're using the correct API endpoints for your QuickBooks environment
