The WP PDF Stamper plugin can be integrated with a plain PayPal Buy Now button so you can send a stamped copy of your eBook that you are selling after the customer makes a purchase.<\/p>\n

To use a PayPal Buy Now button with WP PDF Stamper, you need two pieces of information:<\/p>\n

    \n
  1. The URL of the PDF eBook that you are selling<\/li>\n
  2. The URL of the IPN handling script<\/li>\n<\/ol>\n

    For this integration you simply have to specify the URL of the eBook that you are selling in the “custom” field of the button and set the “notify_url” value to the IPN (Instant Payment Notification) handling script that comes with the plugin. You can get the value of the IPN handling script URL from the “Integration Settings” menu of this plugin. \u00a0This URL should look similar to the following:<\/p>\n

    http:\/\/www.your-domain.com\/?pdfs_pp_ipn=process\n<\/pre>\n
    You need to specify the URL of this IPN handling script in your PayPal button’s code (you specify this URL in the “notify_url” field). For example:<\/p>\n
    <input name=\"notify_url\" type=\"hidden\" value=\"http:\/\/www.your-domain.com\/?pdfs_pp_ipn=process\" \/>\n<\/pre>\n
    This basically tells PayPal to send the payment confirmation notification to this script so the sale can be processed (stamp the eBook and email it to the buyer).<\/p>\n
    There is one other piece of information that you need to include in the button which is the URL of the PDF eBook. This is the file that the plugin will make a copy of then stamp it with the customer details and send it via email. You can specify the URL of the PDF eBook in the “custom” field of the PayPal button. For example:<\/p>\n
    <input name=\"custom\" type=\"hidden\" value=\"http:\/\/www.your-domain.com\/wp-content\/uploads\/my-ebook.pdf\" \/>\n<\/pre>\n
