Connecting robocasa to a static site without cms?

Question

PHP

Hello - friends, tell me who knows, I got one project to work - the site is made on php + js without using a database - it collects information, considers some things and sends it to the mail.
The client wanted to connect robocasa, therefore the 2nd question is
1) is it possible to connect it for such a site - is it real?
2) you can use the option of working with sending to the mail, namely - Method of sending data by Result Url Email

Answer 1

Really
, yes
, what is the problem in case of need to use the base?
store order history at least
+ product ID. does the client have a shop with 2-3 goods/services?
