Add a phone number for a created user. BILL requires organization users to have a linked phone number for initiating risk verification for the organization.
You can check whether a phone number has been added for the user with GET /v3/risk-verifications/phone.
After you add a phone number with this endpoint, you can initiate risk verification for the organization with POST /v3/risk-verifications.
