As someone who has spent a decade working with APIs, I 100% agree. The use cases that are a good fit for “RESTful” APIs pale in comparison to those that would benefit from RPC.

What is the point of having your client translate an action to some operation on a document (read or write), only to then have your server try to infer what action was intended by said document operation.

It pains me that this article doesn’t mention any of the trade offs of each suggestion (POST vs PUT vs PATCH and expandable objects, especially) or of using REST APIs generally.
