Name a shittier API to hook into than Magento's REST API.

Protip: You can't.

[bit of context]
Building 3rd party integrations via their REST API and keep unearthing "WTF?!" architectural design moments. For example: Pulling down products tells you if it has a configurable parent (product to store all master options, etc)... but fuck me if I want to know what the sku of that parent is, or any other means of accessing it!

How the fuck M2 is such a major eCommerce platform is beyond me. WooCommerce in comparison however: Beautiful API, Beautiful documentation, a couple of limitations, no big deal. I love WooCommerce.

M2 makes me question why the hell I became a dev sometimes.
