Instamojo has been around for some time (I used to tell my friends about this "gumroad for India" thing several years ago). Clean, fast process to get started and their API was quite clean (I ended up writing a golang wrapper for their API years ago in the early stages). They even had features to watermark your PDF digital content for each download. I'd definitely recommend you to take a look at it.
