Set Namespace

Sets the app namespace using the owning account's slug or company name and the supplied appName. Falls back to the account slug when no company name is available. A namespace can be set only once. For non-Wix apps, appName must not contain wix (case-insensitive). The exact names google, facebook, and amazon require privileged authorization (case-insensitive). Unlike namespace suggestions, this method does not automatically add a suffix when the derived namespace is already used. Suggestions are not reservations; on a collision, choose a different appName and retry.
