Updating a Product Group. When updating a Product Group, it's important to follow these steps to ensure all existing parameters are preserved and no data is lost:

1. Retrieve Current Configuration - Start by using the Get Product Group endpoint to fetch the current details of the Product Group. This step ensures you capture all existing parameters, as any omitted values will be overwritten or lost during the update.

2. Modify Only What's Needed - Update only the specific fields that need changes, while keeping all other parameters as they were retrieved.

3. Submit the Update - Use the Update Product Group endpoint to send the updated payload. Be sure to include all previously retrieved parameters along with the updated ones, as missing fields will be reset or removed.
