I have integration with Bitrix CRM via curl, there's quite a lot of requests... to Create a lead, create a company, add contact, etc.
When you click send request if all fields are filled in correctly, the response from the server average wait 4 seconds..An example of what the user sees (implemented with JS):
4 seconds is a lot..
How to make CF7 checked all the fields with JS and sent the data and not waiting for a response from the server and immediately said that everything is good?
If such implementation, what problems I may face in the future?
