The ease of use, it makes creating an api for my application very quick! I can't think of anything that i dislike about this product at all its great value for money as well. It is also free to try out so you don't have any risk if there are no features which fit with what you want or needRhizatas ability to export JSON files was perfect when we needed them but now they've added another feature called "XML" - This has been useful too because our clients sometimes struggle to understand json (which rhizata does). We were looking into ways of making APIs quicker to build using other products such as Apigility however after trying rhi zata quickly realised how easy it really made things. Our main problem before was building custom apis by hand; Now everything comes together nicely within one toolset. Creating new endpoints is just 1 click away and then adding fields etc takes only moments. There isn't much.
