Authenticate multiple customers using developer account

I have zoom developer account which i am using for API integration in my website.

Lets say , I have 4 customers who has own zoom accounts (not developer accounts).

Now i wanted to authenticate those 4 customers based on their credentials . Once authentication is done , each customer should be able to create meetings .

If they directly go and see in their Zoom accounts , they should be able to see meetings . please let me know how can this be done .

I’m not sure I understand fully what you are trying to do. Could to expand on the end-to-end process that a user would go through?
