Overview

Let remote storefronts create carts, add items, and place orders through a single signed endpoint.

Problem

Multiple heads (web, mobile, kiosk) need a secure, unified backend for carts and orders without exposing internals.

Solution

OrderFlow exposes /bridge/{clientId}/{action} with HMAC signatures, IP allow-lists, and scoped permissions for cart and order actions.

How it works

Create an inbound connection, restrict by IP, implement a simple signer, then call actions for cart.create/items.add/convertToOrder. The 60s replay window and audit logs keep things safe.
