Magento API OAuth 1.0 Sample Code in PHP

This PHP file is a standalone executable code that will call any Magento API you specify. Inside the code are well-commented code sections that describe the following:

• How to use your API keys
• Creating the OAuth Signature in detail
• Creating the OAuth Authorization Header in detail
• Making the request to Magento's APIs

All you need is a PHP server with the latest version of PHP installed and an internet connection. I have used XAMPP to test this on my localhost:3000. My code editor was VS Code.
