I purchased PDF Stamper in Jan. 2011 and installed it. It works great.
Now I need to integrate with ClickBank. There's a detailed article here on TipsAndTricks-hq.com, but it says to edit the clickbank-config.php found in the /api directory.
Well, there is an /api directory but there is no such file by that name.
FWIW I do have eStore, but that's not part of the picture here since it does not integrate with ClickBank.
What do I need to do to get PDF Stamper working with ClickBank? Where is the clickbank-config.php file???
