Prerequisites:  
- Have your API authentication credentials: auth-userid and api-key.  
- Know the order ID of the Single Domain Linux Hosting order to update.  
- Have the new primary domain name ready.  

Steps:  
1) Prepare a POST API request to the appropriate server endpoint depending on your server location:  
   - US Texas Server: `https://test.httpapi.com/api/singledomainhosting/linux/us/change-domain-name.json`  
   - India Server: `https://test.httpapi.com/api/singledomainhosting/linux/in/change-domain-name.json`  
2) Include the following required parameters in your request query string or POST body:  
   - `auth-userid`: Your integer authentication user ID.  
   - `api-key`: Your API key string.  
   - `order-id`: The integer order ID of the hosting order to update.  
   - `new-domain-name`: The new primary domain name as a string.  
3) Send the POST request to change the primary domain.  
4) Receive the response, which will be a map containing execution details of the domain change operation.  

Warnings:  
- Ensure you have valid authentication parameters to avoid authorization errors.  
- Confirm the correctness of the new-domain-name before sending the request.  
- Use the correct server URL matching your hosting region.
