Discrepancy in fields returned in PersonFields API response vs fields in Person API response

Hi Team,
I am trying out Person Rest APIs to fetch data. While doing so I observed that there are few fields which are returned as part of the data (Person API) which are missing in the metadata API (PersonFields API).

Need information on following :

  1. Why is the difference in fields between the above mentioned APIs ?
  2. For the fields which are not listed in PersonFields API, what are the datatypes of such fields ?
  3. How to identify if its a custom field or not ?

Such fields are as listed below :


Thanks in advance.
