what is the recommended paypal (non pro) process when user purchases login credentials?

[eluser]CI2RULZ[/eluser]
Should user go straight to paypal payment page, then back to website to create login credentials and capturing user data from paypal for db insert?

or

capture the information (including login credentials) first, then pass that to paypal payment pages for easier checkout, then activate the account following successful payment?

The later of the two seems to make more sense to me, however, how can you prove they paid, and how can this update the status of their account post payment? Are there examples of how to set this up? Thanks@!

Paypal does callbacks to update the payment status, so you'll have to implement this in your Paypal gateway implementation.

See https://cms.paypal.com/us/cgi-bin/?cmd=_...o_overview

Should mention, paypal standard is being used, so they will leave the website.

Can you pass a random# generated transactionID# to paypal pages, and it pass it back so you can flag the account to update the status from pending to active?

Have you actually looked at the link I provided?

As first integration method, it says:
Simple integration - Use HTML to integrate Website Payments Standard with your website.

If you click on that, you'll find on that page:
Instant Payment Notification — Receive messages about transaction payments and activity from PayPal through asynchronous, server-to-server communication and automate your online payments with your order fulfillment process; requires advanced programming skills

Which in turn leads to https://cms.paypal.com/us/cgi-bin/?cmd=_...n_IPNIntro, which provides you your callbacks...
