Amazon Integration: every North American marketplace, one shared inventory pool
Amazon's US, Canada, Mexico, and Brazil marketplaces are most sellers' primary Amazon storefronts, running FBM, FBA, and Seller Fulfilled Prime orders side by side under one seller account. The InfiPlex™ OMS is an approved Amazon SP-API application that imports your catalog, pulls orders automatically, and keeps every North American marketplace synced with real-time inventory — alongside every other Amazon region and channel you sell on.

Amazon Seller Central
How the InfiPlex Amazon integration works
InfiPlex authorizes against your Amazon Seller Central account through the current Selling Partner API, imports your product catalog on connection, and pulls new FBM, FBA, and Seller Fulfilled Prime orders on a continuous cadence. Tracking numbers and real-time inventory push back the moment you ship, so every US, Canadian, Mexican, and Brazilian marketplace stays reconciled against the same stock — right alongside every other channel and Amazon region you sell on.
The InfiPlex Amazon sync rail: orders and your product catalog flow in from Seller Central, ship from your warehouse or through FBA, and return tracking and real-time inventory to Amazon — while every other Amazon region and channel stays reconciled against the same pool.
Everything the Amazon integration handles for you
Approved SP-API Connection
InfiPlex passed Amazon's SP-API Security Assessment and is an AWS Technology Partner — orders, inventory, and tracking move over Amazon's current API, not screen-scraping or a retired MWS endpoint.
Automatic Product Import
Download your SKUs from Amazon to get started — title, price, weight, and product image pull in automatically, so you're live in minutes, not days.
FBA Fulfillment Automation
Enable FBA mode per SKU and let Amazon handle fulfillment regardless of originating channel; live FBA inventory levels propagate to every marketplace automatically.
Seller Fulfilled Prime & Managed Shipping
Identify and ship Prime-eligible orders using Amazon's Managed Shipping Services API, print labels directly, and protect your Prime performance metrics. Read the SFP setup guide →
Amazon Custom Order Handling
Customization details from Amazon Custom orders route straight to fulfillment, with optional sync into NetSuite or another ERP.
Multi-Marketplace Coverage
Manage US, Canada, Mexico, and Brazil listings from one dashboard, sharing or segmenting inventory pools by marketplace — your choice.

Migrating off Amazon's retired MWS API?
