I have a shareware site where the user pays $25 for an annual membership. The shareware is free, the membership entitles users to support and an enhanced version of the shareware.
I would like to create a page on my site where the user can make a Paypal payment without leaving the site. Then, I want the user to land on a specific thank you page.
I'm not able to find documentation on how to do this, other than this intimidating, 256 page guide: Gateway Developer Guide and Reference.
My needs are humble. I'm hoping there is a quick-start guide I missed.
Please advise.
PS: I do have the Paypal Advanced ($5/month).
