Being able to create multiple APIs, with different permissions sets, is great. When creating these applications I have to go through several steps and spend more time doing it than necessary. It would be great if there was some kind of wizard where I could just fill in the required fields. Also, being able to use this API outside of the application itself is sometimes difficult, because of the limited permission settings. So far I haven't found anything that I dislike about this service. If you are looking for something simple and easy to use then definitely go for this API solution. I am creating an app for an ecommerce site. I needed an API which could give me access to all products that were sold on the site. I also wanted to integrate this with a chatbot in order to ask questions about products.
