API Design for Logged in User Session

We are building APIs for our app which uses Laravel and Vue.

I have three types of Users:

• Admin

• Brand

• Influencer End-User

We are using a single table to store all the users and have role-based differentiation. While designing the API endpoints should we design three resources for the three types of users and another resource called Session or User for the logged-in user?

How do you design a restful API when you have multiple user roles?
