Amazon Integration: every Amazon channel, one connection

Amazon isn't one channel — it's Seller Central, Vendor Central, FBA, Multi-Channel Fulfillment, Amazon Business, and multiple regions, each with its own portal. The InfiPlex™ OMS, an approved SP-API application, brings all of it into one hub: orders pull automatically, inventory syncs everywhere, and fulfillment routes wherever you ship from.

How it works

How the InfiPlex Amazon integration works

InfiPlex authorizes against your Amazon account through the Selling Partner API, pulls orders on a continuous cadence, and pushes tracking and inventory back the moment you ship. Vendor Central purchase orders, FBA inbound shipments, and Business orders travel the same rail, so Amazon stops being four separate workflows.

Flow diagram: Amazon sends new orders to the InfiPlex Order Management System about every 15 minutes. InfiPlex pushes tracking numbers and real-time inventory back to Amazon, and routes orders to Your Warehouses, Amazon FBA / MCF, 3PL / ERP Systems for fulfillment.

The InfiPlex Amazon sync rail: orders and purchase orders from every Amazon channel flow into the OMS, which routes fulfillment to your warehouses, FBA, or 3PL/ERP systems and returns tracking and real-time inventory to Amazon and all other connected channels.

What’s included

Everything the Amazon integration handles for you

  • Approved SP-API Connection

    InfiPlex is an approved Amazon SP-API application — orders, inventory, and tracking move over Amazon's current API, not screen-scraping or file gymnastics.

  • Seller Central Order Automation

    FBM orders pull about every 15 minutes into the shared queue; ship them from your warehouse, your 3PL, or straight from the OMS with tracking confirmed back.

  • Vendor Central & Direct Fulfillment

    Growth packages cover Vendor Central Direct Fulfillment — and Growth Pro adds Vendor Central Retail — so 1P purchase orders run through the same rail as 3P.

  • FBA Inbound & Multi-Channel Fulfillment

    Manage FBA inbound shipments and use Amazon MCF to fulfill orders from your other channels, all modeled as locations in one inventory pool.

  • Multi-Region Selling

    North America, Europe, and Far East marketplaces connect under one roof, so international expansion doesn't mean a second operation.

  • Repricer & Real-Time Sync

    The Marketplace Repricer (Growth plans) plus real-time inventory sync with per-channel buffers keep the Buy Box pursuit from ever becoming an oversell.
