No API libraries

I just wanted to say that I am evaluating solutions because a client has asked me for a CRM solution. They want me to program it, but I thought maybe I can use Zoho. It seems to have what we need, but I am doubtful because the integration with the API is limited to XML. It is weak, as someone else mentioned, you should have robust API libraries in multiple languages like Twilio. Now it seems there is a lot of functionality in Zoho, but it is sort of half baked. I would rather have something done fully and done right than a half baked solution...
