How to update customer email address through API , at HZ_PARTIES level
Hi
we are updating customers email address  at bulk , so  want to know if any API is available to update the email address at  HZ_PARTIES level 
For the customers  account and contact point is not defined , (no record for customer in HZ_CONTACT_POINTS table).
I have tried to run HZ_CONTACT_POINT_V2PUB.CREATE_CONTACT_POINT api ., but it seems its not creating any record in
HZ_CONTACT_POINTS table and email_address is also not getting updated at HZ_PARTIES
