Currently working in a startup with zero analytics besides Google Analytics. Want to build a lot of more. Where to start? I know some tools such as analytics.js / Mixpanel but what should the analytics strategy be?
My job requires me to use many third party APIs. To compare three APIs (i.e. payments), it normally takes hours to set up just a hello world for one API. Just wondering whether there is any good site allowing me to test or try out many different third party APIs. Thanks.
