This which requires an id. But the response I got after logging in contains no id field. There is only created,email,lastLogin,name,objectId,ownerId,updated,user-token.
I tried with objectId but get:
Action not found
For request 'PUT /v1/users/46A1FD1D_2F80_8F89_FFAF_F413436F2D00'
When you perform login call, the response contains “user-token” property. That property uniquely identifies user session. When you update the user (or do anything in the context of user session, you need to send “user-token” as an HTTP header with your requests.
