 - **API Handler Interface**: Provides a flexible and extensible way to interact with different APIs, including encoding and decoding requests and responses, managing authentication endpoints, and handling API-specific logic.
 - **Configuration via JSON or Environment Variables**: The Go API HTTP Client supports configuration via JSON files or environment variables, providing flexibility in defining authentication credentials, API endpoints, logging settings, and other parameters.
 
+- **Cookie Jar Support**: Incorporates an optional cookie jar to manage cookies effortlessly across requests, enhancing session management and statefulness with APIs that require cookie-based authentication or tracking. This feature allows for automatic storage and sending of cookies with subsequent requests, mirroring browser-like interaction with web services. It can be enabled or disabled based on configuration, providing flexibility in how stateful interactions are handled with the target API.
