Hello!
Task : implement the following functionality. The site has a form for submitting an application for a certain product, for example, for a certain tour. Next to the description of the goods there is a button "Book" or "Leave a request", it does not matter. The bottom line is that after clicking a person enters contact details and they fly away to the company. Next, the company processes this data and in response must send a unique link to the customer to pay for this product through an online payment system.
Accordingly, the question is: how to correctly implement such a model of interaction on the site? The only and, it seems to me, quite absurd version, which so far came to my mind, is to pass through GET parameters a parameter like product identifier or order number that would be generated automatically.
How does it actually work?
Thank!
