User registration

Create a new user account by sending user details to the registration endpoint. 
curl -X POST https://api.example.com/api/register \
  -H "Content-Type: application/json" \
  -d '{
    "userName": "johndoe",
    "firstName": "John",
    "lastName": "Doe",
    "passwordHash": "securePassword123",
    "email": "john.doe@example.com",
    "phoneNumber": "+1234567890"
  }'
The registration endpoint creates both a User entity and an associated UserProfile with default settings:
  • pushNotifications: false

​
Updating user details

  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -d '{
    "firstName": "Jonathan",
    "bio": "Software developer and coffee enthusiast",
    "website": "https://johndoe.dev",
    "accountPrivacy": true
  }'

​
Updating profile fields

You can update any combination of these fields: User fields:

Password updates require providing the old password for verification. Both providedOldPassword and providedNewPassword must be included.
curl -X PUT https://api.example.com/api/users/johndoe \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -d '{
    "providedOldPassword": "currentPassword123",
    "providedNewPassword": "newSecurePassword456"
  }'
If the old password is incorrect, the endpoint returns: 
401 Unauthorized
