Response caching reset via API

Hello Guys,
I hope you are all well.
I am experimenting with caching to improve perf of my app and one of the use case I have is caching the response on the user level (auth-level) but I want to be able to scrap it anytime certain API gets hit.

Basically my users create a training plan which lasts a couple of months hence I see a lot of response caching potential in many APIs however they can update or re-create a plan anytime (although on average they would not it often). I was thinking if there is a way of plugging a response cache reset of a certain API under the stack of another API. Delete cache does not seem to be the right solution as we cannot access cached response there just variable we previously pushed.
Basically if I cache an API responses for 24 hours now, there is a risk that user will happen to recreate the plan and won't be able to see the updated version for 24h.
