Overview

This node interacts with the OpenCart API to manage shopping cart operations, specifically adding a product to the cart. It allows users to specify the product ID, quantity, and product options in JSON format. This is useful for automating e-commerce workflows where products need to be programmatically added to a customer's cart, such as in custom checkout processes or inventory management systems.

Use Case Examples

1. Adding a product with specific options and quantity to a user's shopping cart in an OpenCart store.
2. Automating cart updates based on user selections in a custom front-end application.
