We need to connect a specific API to the Calculated Fields Form in Wordpress.
This should be a simple work for developer.
You would need to do the following:
1 - In a specific event, like text box focus change, we need to send the request to the server with the text box value.
2 - Receive and answer from the server
3 - Present it in another list box. Similar when a button is pressed, you send a GET command to the server.
Please give us offer.
