Answer 1

You can use admin_post_(action).

When you create your form in front-end you add the input

<input type="hidden" name="action" value="nome_da_funcao">

Inside your plugin you add the Hooks

add_action( 'admin_post_nome_da_funcao', 'my_function' );
add_action( 'admin_post_nopriv_nome_da_funcao', 'my_function' );


function my_function() {
//Seus codigos e request aqui

}
