createClientFromRequest

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 bypasses entity access rules and field-level security. To learn more about the Base44 client, see createClient().

Parameters

request

Request

obrigatório

The incoming HTTP request object containing Base44 authentication headers.

Returns

asServiceRole

object

obrigatório

Provides access to supported modules with elevated permissions.Service role authentication provides elevated permissions for backend operations.
