  • Can Linklok handle orders containing non tangible goods?
    There are a number of ways to setup Linklok if you sell items that are shipped as well as downloads. The best way is to setup an email and download page template with a section for shipped goods. This section will be displayed by Linklok only if items are ordered that Linklok doesn't know about (assumed to be tangible products). This template section could for example explain your shipping policy.

  • When I return to my download page I see an error message
    Check that in Paypal you have enabled Auto Return and pointed it to http://www.yoursite.com/linklokipnret.php (not linklokipn.php). Also check that PDT is enabled and that the PDT token value provided by Paypal is exactly the same as you have set in $PDTtoken.

  • I receive the download email when testing but not with a live order
    There are a number of reasons why the download email will not be sent with live orders even though it works with testorder,htm or the manual order form.

    1) Check that the email address set in $PaypalEmail is your primary email address on the Paypal account. You can still use any email address in your buy buttons though of course.

    2) The item_number in your buy button must match the product id in the product defintion. For example if you id1 in the product definition then the item_number in your button must also be id1

    3) IPN must point to http://www.yoursite.com/linklokipn.php (not linklokipnret.php).

    4) The amount in the buy button must be the same or more than that set in the product definition.

    5) Check that your Paypal account is verified. IPN will not work normally for unverified accounts.
