How to customize Strapi backend (content-manager) controllers, services and validation?

Hi @DMehaffy !

I am having an issue with the new documentation. Could you please let me know what are the new wrapping that’s documented? I have tried adding a function ‘create’ into the coreController when it is being created, and also tried adding a function ‘create’ into the coreService when it is being created, but it does not seem to access any of them when I’m creating a new entry from the content manager.

What am I missing?

Thanks for your help in advance
