Confirm or give up ownership of a phone number

Answer an ownership question about a phone number hosted with another provider.

Send still_own: true to confirm you still own a number whose ownership_status is pending_confirmation or flagged; its status returns to verified and, after a carrier change, the new carrier becomes the one on record.

Send still_own: false to report that you no longer own the number. It is removed from Number Reputation immediately, whatever its current status, and the response shows it with ownership_status: removed.

POST

{enterprise_id}
