Can one rely on Paypal IPN solely to record purchases?

Question

I\'m setting up a simple \'buy now\' transaction from a website with these major steps:

1. Select product from price list
2. Review selection (amounts, tax etc)

Answer 1

I have developed a number of eCommerce sites, and in practice you always want to record what you can in case of any 'accidents'. You own data is probably more informative.

Like you said, yes you can do this, but I would suggest that it is not a great idea.
