See How It Works APIWORX connects the systems your business already uses and takes responsibility for the agreed integration workflows after go-live. The exact objects, direction and cadence are fixed in writing during scoping. ERP + eCommerce Specialists Managed & Monitored Integrations Expert Integration Team APIWORX Provides the Service ## Yes. APIWORX connects Shopify and Amazon Vendor Central. But connecting the applications is only the beginning. The work that costs you time sits in the process running between them. APIWORX automates that process end to end — the objects moving between Shopify and Amazon Vendor Central, the ownership rules that decide which system wins, the exceptions when a record will not post, and the monitoring that tells someone before your team finds out from a customer.

The two models compete for the same stock and must not be reported as the same thing. ### What needs to be in place - An active Amazon Vendor Central account, with the applicable vendor programme confirmed. - Shopify or Shopify Plus, with the locations that hold sellable stock identified. - A finance system or process that can issue wholesale invoices — Shopify is not assumed to do this. - A warehouse or 3PL that can produce carton-level shipment detail. ### When you may not need this If Amazon wholesale is a single small PO a month, manual handling is reasonable. This work pays off when wholesale demand starts competing with DTC stock, or when acknowledgement and shipment detail cannot be produced reliably by hand. ### What is out of scope - Shopify is not a wholesale invoicing system. Where invoices must be produced, we scope which system issues them. - Amazon commercial terms, cost negotiation and programme enrolment remain yours. - Chargeback disputes remain yours to file; we make the transaction chain traceable. ## What actually moves, and who owns it A representative scope. Note where the destination is deliberately not Shopify.

Shopify is built around consumer orders. Forcing wholesale into the DTC order model is what breaks reporting and margin analysis. - Wholesale POs are represented deliberately — as their own record type, or held outside Shopify entirely. - Wholesale cost is never mixed with consumer retail price. - DTC and wholesale channel reporting stay separable. - Seller Central 3P activity, where you also run it, is scoped as a separate flow. ### Inventory and warehouse responsibilities One pool of stock, two demand streams with very different consequences. Missing a DTC sale costs a sale; missing an accepted Amazon PO costs scorecard standing. That priority has to be explicit. - Shopify remains the quantity of record across both streams. - Allocation policy agreed — how much stock wholesale may commit, and what protects DTC. - Accepted PO quantities reserved so the same units are not promised twice. - Warehouse or 3PL produces the carton detail Amazon requires; we carry it, not invent it. ### Which interface handles each vendor transaction Different vendor transactions travel over different channels depending on your account and programme. Mapping that honestly, per transaction, is what stops a project from stalling mid-build. - Each in-scope transaction is listed with its confirmed interface before build starts. - Standard retail POs and direct-fulfilment programmes are scoped separately. - Where a transaction cannot be automated for your account, we say so in the plan rather than promising it. - Existing EDI or network arrangements are usually retained. ## Reliability and ownership Amazon notices missed documents faster than most teams do. These arrangements close that gap. - Every run is logged with the source record reference so a document can be traced end to end. - Failed messages are retried on a defined schedule; anything that still fails lands in an exception queue rather than being dropped silently. - Duplicate prevention keys on the source system's own identifier (order number, PO number, document ID) so a replayed message does not create a second record. - Exceptions are worked by the APIWORX team and escalated to your named contacts when a business decision is needed. - Mapping changes — new SKUs, new accounts, new dimensions, new trading-partner requirements — are handled as part of the ongoing engagement. - Response commitments and support windows are set in your agreement; this page does not state an SLA. ## Document cycle at a glance Standard EDI document reference The standard transaction sets used in Amazon vendor programmes; applicability is confirmed per account. | 850 — Purchase order | Amazon → you | | --- | --- | | 855 — Acknowledgement | You → Amazon, per line | | 856 — Advance ship notice | You → Amazon, carton level | | 810 — Invoice | You → Amazon, referencing the PO | | 860 / 865 — Change and response | Pre-despatch changes | ## Scope and questions Can Shopify hold the Amazon purchase orders? It can represent them, but Shopify is built for consumer orders. We help you decide whether representing wholesale POs in Shopify or holding them outside gives you cleaner operations and reporting. Will wholesale demand oversell our DTC store? That is exactly what the allocation policy prevents. Accepted PO quantities are reserved against Shopify stock so the same units are not sold twice. Where do vendor invoices come from? From the finance system you nominate. We do not assume Shopify issues wholesale invoices. Is direct fulfilment included? Only when your account is enrolled and the applicable interface is confirmed. It is scoped as its own flow. Do you also handle Seller Central? Yes, as a separate integration. Mixing 1P vendor invoices with 3P settlements is a common and expensive reporting mistake. How is scope determined? By the transactions in play, the vendor programme, your warehouse capability and the ongoing support you want.
