Amazon Seller API integration and platform bridging
Getting Amazon Seller to talk to the rest of your systems means keeping listings, settlement reports and order acknowledgements correct on both sides, automatically. That is the integration work we do.
Fixed-scope engagements, delivered by UK-based integration engineers. Documentation and source code handed over on completion.

- ✓FBA & FBM flows
- ✓Settlement posting
What we can connect Amazon Seller to
Amazon Seller holds your orders, listings and settlements. Every other system in the business holds a partial copy of the same data. Our role is to make one the source of truth and keep the rest aligned — through the Amazon Seller API, webhooks where they exist, and a bridging layer where the destination platform has no usable interface of its own.
Ecommerce platforms
Keep listings, prices and stock aligned between Amazon Seller and your own storefront, with one owning system per field.
Shopify, WooCommerce, Magento
ERP and stock control
Feed Amazon Seller from a single stock master with per-channel buffers, and ingest Amazon Seller orders into one order book.
NetSuite, Dynamics, Linnworks, Cin7
Accounting and finance
Post Amazon Seller settlements — sales, fees, refunds and marketplace tax — into the ledger so the bank reconciles.
Sage, Xero, QuickBooks
Warehouse and fulfilment
Route Amazon Seller orders to the 3PL or WMS and return valid tracking within the marketplace SLA window.
Mintsoft, Peoplevox, FBA hand-off
Repricing and content
Connect Amazon Seller to repricing and content tools while keeping your system of record authoritative for price floors.
BQool, RepricerExpress, in-house rules
Bespoke and legacy systems
A legacy listing tool or in-house catalogue connected to $name through a controlled, rate-limit-aware bridge.
SQL Server, SFTP, SOAP, CSV
Common Amazon Seller integration use cases
Each is a defined, testable data flow rather than an open-ended development project.
02
Order ingestion
Amazon Seller orders are created in the ERP or OMS with address and tax normalised and allocation in payment order.
Outcome: one fulfilment queue across channels.
03
Despatch SLA compliance
Fulfilment and valid tracking are written back to Amazon Seller inside the required window, automatically.
Outcome: late-despatch metrics under threshold.
04
Settlement posting
Amazon Seller payouts are posted to the ledger with fees and refunds separated for clean reconciliation.
Outcome: marketplace P&L visible monthly.
05
Listing and price control
Prices and content flow to Amazon Seller from your system of record, with floors enforced against repricers.
Outcome: no race-to-the-bottom pricing errors.
06
Multi-account consolidation
Several Amazon Seller accounts or regions are consolidated into one stock and order pipeline.
Outcome: one operational view.
How a Amazon Seller API integration is delivered
Four stages, fixed scope agreed before any code is written. Typical delivery for a single-system integration is two to four weeks.
Stage one
Discovery and data mapping
We document the systems involved, the direction of each flow, and every field that must move — including the awkward ones such as tax, discounts and multi-currency.
Output: written integration specification.
Stage two
Fixed scope and estimate
The specification becomes a fixed-price proposal with a delivery schedule and defined acceptance criteria. No time-and-materials open ends.
Output: costed scope for sign-off.
Stage three
Build and testing
Development against a Amazon Seller development or sandbox environment and a sandbox of the destination system, with your own data used for acceptance testing.
Output: tested integration and test evidence.
Stage four
Go-live and handover
Controlled cutover with monitoring in place, followed by handover of code, credentials and documentation, and a period of hypercare support.
Output: live integration, owned by you.

Request a scopeAmazon Seller API bridging when there is no direct connector
The hard part is rarely Amazon Seller itself. It is making sure the system on the other end of the wire — often older, undocumented, or maintained by someone who has since left — still gets what it needs, in the shape it expects.
Concretely: a queue so bursts don't overwhelm either side, retries failed calls against Amazon Seller's Selling Partner API (SP-API) limits, and a full transaction log so commission and fee reconciliation is never in question. Amazon Seller can change its API version without anything downstream noticing.
If there is no usable interface at all, the fallback is a flat-file exchange, a direct database connection, or a small REST wrapper we write and host ourselves — whichever fits what is actually there.
Included in every bridge we build
- →Error handling with alerting when a transfer fails
- →Automatic retries that respect the platform API rate limits
- →A transaction log for tracing any individual record
- →Idempotency so a repeated webhook cannot duplicate a record
- →Field-level mapping documentation you can hand to any developer
- →A staging environment that mirrors production
Amazon Seller integration FAQs
A single-direction integration between Amazon Seller and one business system is typically delivered in two to four weeks, including discovery, field-level mapping, build against a sandbox, acceptance testing with your own data and supported go-live. Multi-system programmes are phased.
Yes. Where the other platform has no modern API we bridge it — scheduled file exchange over SFTP, a database-level connector, or a middleware layer that exposes a documented REST interface to Amazon Seller while speaking the legacy system's own protocol behind it.
You do. Source code, credentials, configuration and documentation are handed over on completion, and there is no licence fee for continuing to use it. Monitoring and change support are available under a separate agreement.
Major platforms version their APIs and support each version for a defined period. Integrations under a support agreement are reviewed each release cycle and migrated ahead of deprecation dates; for handed-over work the version dependencies are documented so your team can plan.
Other platforms we integrate
Each platform has its own integration guide covering authentication, available endpoints and typical data flows.
