Challenges Building and Integrating Test and Live API keys

[Miracle]

I want to create a system that works similar to stripe. There'll be live API keys, as well as test API keys. I have been thinking of how to implement this architecture, and I am not sure the best way to go about it. I found a similar question on this but it didn't help much.

Architecturing testmode/livemode using OAuth 2 token

My current progress is basically:

• I have decided to use https://github.com/James1345/django-rest-knox instead of DRF's default authtoken because knox supports multiple token creation and I thougt I needed that feature.
• I intend to create tokens as pub_key_<token> and test_key_<token> and remove or strip the prefix before authentication
• I intend to create a LiveAccount Model and a TestAcoount model.

However, after authenticating the request from a test api token, it's unclear how to route or perform requests to TestAcoount instead of LiveAccount.

Please any ideas or a better implementation strategy is highly welcomed
