eBay API integration and platform bridging

eBay rarely runs alone. We build the integration that keeps listings, settlement reports and order acknowledgements in step between eBay and the rest of your stack, without a nightly spreadsheet in between.

Fixed-scope engagements, delivered by UK-based integration engineers. Documentation and source code handed over on completion.

  • Inventory & Offer model
  • Order pipeline

What we can connect eBay to

eBay holds your listings, orders and offers. 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 eBay 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 eBay and your own storefront, with one owning system per field.

Shopify, WooCommerce, Magento

ERP and stock control

Feed eBay from a single stock master with per-channel buffers, and ingest eBay orders into one order book.

NetSuite, Dynamics, Linnworks, Cin7

Accounting and finance

Post eBay settlements — sales, fees, refunds and marketplace tax — into the ledger so the bank reconciles.

Sage, Xero, QuickBooks

Warehouse and fulfilment

Route eBay orders to the 3PL or WMS and return valid tracking within the marketplace SLA window.

Mintsoft, Peoplevox, FBA hand-off

Repricing and content

Connect eBay 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 eBay integration use cases

Each is a defined, testable data flow rather than an open-ended development project.

01

Stock synchronisation

One master pushes availability to eBay with a per-channel buffer so fast movers are not oversold.

Outcome: account health protected.

02

Order ingestion

eBay 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 eBay inside the required window, automatically.

Outcome: late-despatch metrics under threshold.

04

Settlement posting

eBay 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 eBay from your system of record, with floors enforced against repricers.

Outcome: no race-to-the-bottom pricing errors.

06

Multi-account consolidation

Several eBay accounts or regions are consolidated into one stock and order pipeline.

Outcome: one operational view.

How a eBay 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 eBay 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.

eBay API bridging when there is no direct connector

Most integration problems are not really about eBay — they are about whatever sits on the other side of it: a legacy system, an in-house database, or a second platform with its own idea of what a record should look like. The bridge has to reconcile both.

That layer normalises data formats, holds a queue so neither platform is overwhelmed, authenticated the way eBay expects — OAuth 2.0 — and records every transaction so a disputed record can be traced end to end. It also isolates you from change: when eBay deprecates an API version, only the bridge is updated.

Where a platform genuinely has no interface, we work with what exists — scheduled SFTP file exchange, direct database connectors, or a documented REST wrapper we build and host on your behalf.

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

eBay integration FAQs

A single-direction integration between eBay 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.

Other platforms we integrate

Each platform has its own integration guide covering authentication, available endpoints and typical data flows.
