Email and phone are optional again when creating users

Availability: Sandbox since November 5, 2026 · Production since November 5, 2026

email, phoneNumber and phoneVerifiedAt are optional again on user creation (POST /private/v1/users). A recent change had made them required, and that change has been reverted. Requests that omit them are accepted again, and nothing changes for integrations that already send them.

• When supplied, phoneNumber must still be 10 digits with no country code and no formatting, and email must still be a valid address.
• emailVerifiedAt is still required.

The same applies to one-click user creation: email is optional, and emailVerifiedAt is still required.
