Retrieve form data on submission in custom PHP page

Hi,

I am creating a wordpress website and using Forminator plugin. I want that after user submission I can get the data of the form in a custom PHP page where I will perform some operations on the data and return the processed data to another/same page.

Few options :-

1. If there is any way to obtain the current form’s submitted data using attribute_Id/ shortcode in PHP code?
2. If I can get the data in POST request after form submission on next page?

Please suggest the ways to implement above two queries.

Thanks.
