User modul inbuilt REST endpoint

Hello. We have to push a large amount of users to/from CRM from/into Workspace(a product of our company). The natural choice for this would be the existing in-built REST endpoint for the Users module. I searched high and low but I could not find in the documentation anything about the password. Does the endpoint expect the password already hashed or does it expect plaintext and he will do the hashing for me? Is there any difference between the Users endpoint and a generic module endpoint?
