This plugin is a field type for Advanced Custom Fields that connects to the Google Maps Directions API. It is designed for developers building websites that need to display routes, travel times, or distance information, such as for event locations, service areas, or trip planners. The tool handles the API request and caches the response directly within the custom field data.

• Directions Data Caching: The plugin requests and stores the full directions data from Google Maps, including the encoded polyline, steps, duration, and distance. This cached data is then available for front-end display without repeated API calls.
• Coordinate-Based Input: Users specify a route by entering start and end coordinates directly within the field's interface. The system also supports adding optional waypoints for more complex journeys.
• Front-End Integration: The stored data is structured to be easily passed to JavaScript, making it straightforward to integrate with embedded Google Maps or custom mapping applications on your site.
• One-Click Generation: After entering coordinates, a single click on the 'Generate' button triggers the API request and updates the field with the latest directions data, ensuring the stored information is current.
• Developer-Focused Workflow: The tool operates by storing only the generated API response, not the raw input coordinates. This approach requires regenerating the data if coordinates change, providing a clear save-state mechanism within the CMS.
