The application requires two API keys to function:

1. Application API Key: Used for authenticating requests between the frontend and backend

   • Set this in TrendyolProductAPI/appsettings.json as ApiKey
   • Set the same key in frontend/src/services/api.ts as API_KEY

2. OpenAI API Key: Used for AI-powered product transformations

   • Set this in TrendyolProductAPI/appsettings.json under OpenAI:ApiKey

For security:

• Never commit real API keys to version control
• Use the sample configuration file (appsettings.sample.json) as a template
• Keep your API keys secure and rotate them regularly
