I like that it’s extremely easy integrate with our systems and can be used from almost any language or OS platform, including mobile! The fact that some of my colleagues have been using different languages means there's bound to be someone who has an experience in another programming language which would have helped improve the product if needed. There are quite a few free APIs available but this one is definitely more costly than others as well. It helps us bridge the gap between internal database applications (SQL server & MS Access) and third party ones so we don't have to keep our own copy of the datasets up to date. This saves us time on manual processes and makes life easier for business users when accessing data sets. I like the ability to use Data Gateway API in multiple ways. I have used it for multiple purposes, from simple data import to complex ETL processes. I can say that I have never encountered any issues. There are no downsides to it. I've only heard good things about Data Gateway API. I have used it for data import and cleansing. It has been very helpful.
