User Seat Type Information Through Airtable API

[YA_RAMSAMKER]

Hi 

I am having difficulty getting information on users seat types (builders,contributors,viewers)

I have tried the below API calls 

1.Get Base Collabrators

2.Get User By ID 

3.SCIM list users 

I cant seem to find the place where this information is stored 

Using enterprise edition 

Please help 

Thanks
