P1 PHR identity and profile
P1 is the patient side of M1. M1 is how a hospital system creates an ABHA; P1 is how the patient's own application does it, and how it maintains the account afterwards.
What is in it
Registration and login, the profile the patient reads and edits, family members they manage on one account, and DigiLocker documents they pull in.
The full operation list is in the P1 PHR identity and profile API reference.
