Google has some of the worst APIs I've ever seen. No wonder you hate REST HTTP APIs. Take a look at FreshBooks API. They have a more complicated application (in terms of model complexity and ACL complexity, not scale) than most of Google APIs and besides the fact that they only support XML, their API is really fucking good. It is unsurprising and it it's been around a good long while. Would you really rather FreshBooks use an RPC API? /setup_payment_for_invoice /pay_payment_on_invoice /allow_contractor_to_submit_expenses /create_new_time_tracked_amount It would be brutal.
