Use like shopify APIs elsewhere

[lucasvil3la8]

Hi, I'm developing a project and I need to use some Shopify APIs.

-Analysis API

-Client API

-Discount API

-Event API

- Inventory API

- Online store API

- Request API

-Product API

-Shop property API.

I would like to know if to use these APIs I need to have a separate CMS or use Shopify's same
