I’ve also been searching for a manageable API integration platform. I had a certain amount of success with the now defunct Yahoo! Pipes, but am at a loss since Yahoo shut down Pipes.has recently suggested to me , , and/or , which are not what I’m looking for. I want a *visual* middleware, along the lines of the highly modular Salesforce, but for experimental artificial intelligence instead of severely restricted to conventional business solutions. I think this would require a uniform underlying data transport mechanism, or messaging infrastructure. Yahoo! Pipes was nice in that CSV could be easily plugged-in via webhook, which played well with XML.
