Elementor Custom Form Action ( HTTP Post)

Hello dear WordPress Developer,
we want to develop a custom action after submitting the Elementor Form. It is about an automation for receiving a free trial access. This should be done using an HTTP POST with the following JSON:

interface WebsiteSignupRequest {
restaurantName: string;
name: string;
email: string;
phone: string;
password: string;
partnerId?: string;
}

I ask for a quick implementation.
