User Ssocreate
Create a SSO user on Zoom, return the created user ID. The API is provided for enabled 'Pre-provisioning SSO User' option. User created in this way has no password. If it is not a basic user, will generate a Personal Vanity URL using user name (no domain) of the provisioning email. If user name or pmi is invalid or occupied, will use random number/random personal vanity URL.
