Connect Sellfy and amazon

Connecting Sellfy and Amazon for a company using both systems could enable the transfer of product, inventory, and order data between the platforms. Such a connection could help automate updates, reduce manual entry, and support centralized management of sales and fulfillment processes across both channels, improving operational efficiency and data accuracy.

You can build this integration on the System2System platform. We design the connection between Sellfy and amazon around the way you work — not as an off-the-shelf connector, but to fit your systems.

Why connect Sellfy and amazon?

A company that uses both Sellfy and Amazon could benefit from connecting these systems to enable data exchange between their online storefronts and marketplace operations. Without such a connection, staff may need to enter product, inventory, and order details into both platforms separately, increasing the risk of errors and consuming additional time. Duplicate data entry can lead to inconsistencies, such as mismatched product descriptions, pricing discrepancies, or inventory levels that do not reflect actual stock. This can result in orders being accepted for out-of-stock items or decisions being made based on outdated information. If records in Sellfy and Amazon are not kept in sync, it becomes difficult to maintain a unified view of sales, inventory, and customer data, which can undermine reporting accuracy and operational efficiency. The kinds of data that could be exchanged between systems like Sellfy and Amazon include product listings, stock levels, order information, and customer details. What can actually be exchanged depends on what each system exposes through its API and is determined per situation.

How System2System builds an integration

Connectors

We connect to each system through the interface it offers — an API, a database, a file exchange or a webhook — and handle authentication, rate limits and retries.

Mapping

Fields rarely line up one to one. We map and transform the data so both systems receive it in the shape they expect.

Workflow

We define what triggers an exchange, in which direction data flows and which system takes precedence when the two disagree.

Monitoring

Every exchange is logged. Failures are flagged and can be replayed, so nothing disappears without anyone noticing.

What can actually be exchanged?

That depends on what Sellfy and amazon make available through their APIs, on the licences and modules in use, and on the version each system runs. Which records are synchronised, in which direction and how often, is something we determine together before any work starts.

We are happy to look at your specific situation and tell you what is feasible — including when the answer is that it is not.
