I want to auto-place orders of books on amazon and ingramspark using API or something like that

Using JS your best bet is to build a bot t scrap and then if your website is linked you can create and endpoint using node or something else to place the order through the bot using Casper JS not a perfect solution but it will run as long as Amazon doesn't change their markup

I can solve this problem in Python if you inbox me the details.. I will submit you detailed plan if you inbox me details of project.
