4. Customers will receive an confirmation email about the order. In this email, they can get the purchased documents (sent as attachments if you enable this feature). They can also get the documents by clicking on the download links sent in this email (if you enable this feature) .
This feature is available in the extension. Didn't you receive an email contains the extension after you completed the order ? Did you see the order from back-end of your site after you complete the order ?
I did fix it... I was confused as to the email when i tested out the software, I did have to put this [DOWNLOAD_DETAIL] in the email body so that my document was attached in the email... Everything is great and you did a fab job with Document Seller... Thankyou for your response!
