API Interface - Switch or Two Different Interfaces

Question

I am studying interface design.

Here is what interests me.

• Some of the open APIs support two different interfaces for switching. those. install the circuit like. It separates as an interface (e.g. undo)
• What is the advantage of separating these two (splitting into two interfaces makes the end user more complex in my view).

I doubt it, as it can be implemented when switching.

i.e. the user sends item_id and user_id. server check the database (this element is already liked or not) and update.

Thanks for the answer!
