createClientFromRequest(request): Base44Client
Creates a Base44 client from an HTTP request. This function is designed for use in Base44-hosted backend functions. For frontends and external backends, use createClient() instead. When used in a Base44-hosted backend function, createClientFromRequest() automatically extracts authentication tokens from the request headers that Base44 injects when forwarding requests. The returned client includes service role access using base44.asServiceRole, which provides admin-level permissions. To learn more about the Base44 client, see createClient().
