Scim API vs normal user add/delete api for zoom

I am trying to understand the difference between using SCIM API for Zoom

https://developers.zoom.us/docs/api/rest/reference/scim-api/methods/#overview

vs Zoom user API

https://developers.zoom.us/docs/api/rest/reference/user/methods/#operation/users

what would be the difference here between both of them?

It looks like both of them have

  • Get all users
  • Create new users
  • Deactivate a user

Api. What difference would it be if we are building custom user access management?
