Below is my requirement:

1. Want to add a page on my website at Zoho - I know how to do this

2. This page will contain link to download product or say a word document as of now - I know how to do this

3. I will purchase Pay Pal Addin 

4. Only when the user succeeds in making payment he should be directed the download page

Are above points possible? in Zoho? Thanks in advance.
