I like that this product can be used to create new RESTful services easily without writing any code as well with support of JSON or XML formats so no worries about coding! This tool has been very helpful in our work since we are able to use existing SOAP web service endpoints which have not yet implemented an OAuth flow (yet).
We've also created some custom flows using Java/JAXB classes where there was nothing available out of box but now they're working great too thanks again. There's something called "Api gateway" feature when adding api endpoint configuration under apim manager tab if i'm correct what does exactly mean? Maybe someone knows more details regarding its usage please let me know because currently my understanding isn't enought good at all. The best thing compared to other similar products such jira itself would probably be how easy management panel could look after installation process by just copying & pasting files instead going through complicated setup procedures etc.
