Mark an email address as verified by an administrator
POST /v1/users/{user_id}/emails/{email_id}:verify · permission users:write
Marks the address as verified on your authority. No code or link is sent to the user, and the verification method is stored as admin_api, so it is not proof that the user controls the mailbox; prefer :send-verification when you have not verified the address yourself. If the address is already verified nothing is written and 200 is returned. Unverified copies of the same address on other accounts of the environment are removed. The change is written to the management audit log as user.email_verified with the API key as actor, and emits user.updated.
