What kind of idea should I base on for creating the relationship between the API methods in API Project and scripts?

Question

What kind of idea should I base on for creating the relationship between the methods specified in the API Project and the processing content of scripts?

I would like to confirm this because I think that the following combination is possible:
- Method specified in API project: DELETE
- Script to be associated with API project: Data registration

Answer

As a product, there is no specific rule or policy between the processing content of the methods specified in the API project and the scripts specified for each method.

As advice, assuming that other API projects also exist, it is suggested for users to create the relationship from the perspective of whether they are easy for users to manage.
