How to get a development account?

Hi, I am form a team for Advertising development house, I have a few questions would like someone to answer:

  1. Is there a list of API of breaking changes over the last few versions? We are concerned about the stability of API interface.
  2. Is it possible for us to get a development account and client id/secret so that we could evaluate the platform?

Hi, barnabava:
