Products like Paragon which to me is a scripting system that connects between various ecosystems like Stripe, Twilio, etc., are popping up all over. This silly way of using the HTTP primitives to coordinate between programs is a bizarre historical artifact, that screams out for the equivalent of Apple events, whereby a program publishes a set of operations and remote systems can then control it. It is downright crazy to convert his all to URL's with clumsy encoding systems, and pathetic error reporting such as 4xx codes. There were great solutions in the single computer world, why can't this be generalized across machines? We shouldn't need a coordinating tool that is proprietary.
