Add a local Payment Gateway to a registration form

Hello Team Wappler,

My first attempt to integrate a payment gateway. I would like to use a local payment gateway to process payments for the simple registration form shown below. The payment gateway documentation located here has provided me with a unique app_id and app_key which i have to include in the config(done).
I have a dbTable that is populated when the form is submited.

I need help with next steps. I have checked out the stripe tutorials but I get more confused . I am hoping for directions like

1. Create A dynamic event for this.
2. Add post variable here and there
3. Create connection here and there.

Happy New year to all.
