Developing Apps for Features restricted by Affiliate & Partner

I’m developing an application that ideally will dynamically update Custom Channel Point Rewards through the API. Problem is I have no way of testing my application, because I am neither a Partner or Affiliate and creating custom channel points rewards is not available. What would be the best way to deal with this? I’m I just SOL unless I go through the process of being coming Affiliate?

Check out the twitch cli. Some of the functionality was designed for this purpose.
