eBay Integration: Connection, Orders and Stock

eBay integration connects your eBay seller account in the US and Europe to a single panel. The connection requires an application key, a secret and a refresh token. Once connected, orders land in the panel and stock and prices update together with your other stores; profitability is tracked for USD lines as well.

What credentials does eBay integration need?

The connection requires an application key, a secret and a refresh token, all belonging to your eBay seller account. Entering them establishes the connection and starts the first synchronisation. No separate server, static IP or developer support is required; a seller can complete the setup alone.

The first synchronisation pulls your existing products and open orders into the panel. The critical step is verifying barcode and stock code matching. If matching is wrong, automatic updates write stock to the wrong product and you only notice when the wrong order arrives, so check the catalogue before enabling automation. Small catalogues take minutes; catalogues with thousands of products deserve a dedicated session.

What works on eBay integration?

What works: Order flow: new orders land in the panel, picking and packing run from there, shipping labels print in bulk; Returns: return requests collect in one list and incoming parcels are verified by barcode; Customer questions: questions are queued and a draft answer is produced from product data. Stock and price are also managed centrally, so a change in one store propagates to the others by rule.

NOT IMPLEMENTED YET for this marketplace: creating new listings from the panel. We state this plainly, because claiming "it does everything" only produces disappointment after setup; knowing the gap in advance removes the "why can’t I see it here" question later.

How do you become a eBay seller?

Applications go through eBay’s own seller channel and the marketplace sets the acceptance criteria. Those criteria change over time and by country, so no fixed document list is given here; always confirm current requirements on the eBay seller page. Publishing an unverified document list would send sellers into the wrong preparation.

Preparing these speeds the process: legal entity and tax registration, a bank account able to receive payments, product images and descriptions, and barcode data. In cross-border selling, having descriptions in the target market’s language directly affects listing quality.

Once the store is open, the only integration task is entering the credentials. No technical setup is needed; the first synchronisation starts as soon as the connection is established.

How is profit measured correctly on eBay sales?

Profit is not sale price minus commission. The real profit on an order is what remains after commission, shipping cost, platform service fee, return cost and the product’s purchase cost. Some of these settle only when the payout statement is issued, so any figure calculated at sale time is by definition an estimate.

The correct method has two stages. Before the sale, a category-based estimated rate guides pricing; the aim is to prevent a loss-making price from the outset. After the sale, the most accurate source is the order itself — the marketplace’s order and payout data carries the actual deductions for that line. A realised profitability report must use that value rather than the estimate.

Selling in USD adds a second variable: sales settle in USD while costs arise in TRY, and the exchange rate determines the margin at collection time rather than at sale time. Which rate was used therefore matters as much as the margin itself.

Can eBay share stock with other marketplaces?

Yes. If you sell the same physical product on eBay and elsewhere, overselling is inevitable unless a sale in one place reduces stock in the other.

A shared stock pool solves this at pool level: physical stock is held once, distribution to stores follows a rule, and a sale in any store draws from the pool. Two stores no longer show the same 10 units as 10 units each. Because marketplace queues are not instantaneous, keeping a small stock buffer is the cheapest insurance against overselling.

Which market does eBay serve and in which currency do you sell?

eBay’s primary market is the US and transactions run in USD. The panel holds this store’s orders in USD; because your costs arise in TRY, a second variable enters the profit calculation: THE EXCHANGE RATE.

Currency risk is where most sellers underestimate the exposure. The margin is set not when the sale happens but when the money converts to TRY. If the rate moves against you during the payout term, the profit you calculated at sale time may have evaporated by collection. A realised profitability report must therefore use the order’s own deduction data and the collection rate, not an estimated percentage.

The second difference is tax treatment: how tax applies to the marketplace’s fees varies by country. In one market fees are quoted tax-inclusive, in another tax is added on top, in a third the marketplace itself collects and remits the sales tax. Computing all three with one formula silently produces the wrong profit, which is why the panel keeps the country rule as a separate field.

How do you become an eBay seller from Turkey or from abroad?

FROM TURKEY: Selling into the US from Turkey is a cross-border transaction subject to export rules. Sales in small parcels fall under Turkey’s MICRO EXPORT regime: the shipment is declared with an ETGB (electronic commerce customs declaration), and that declaration grants FULL VAT EXEMPTION — output VAT is zero, while the input VAT you paid when buying the goods becomes refundable. This is the most overlooked advantage of cross-border selling; a seller who does not file the declaration loses both the exemption and the refund.

The panel reports this separately: which orders fall under micro export and their totals are collected in a dedicated view. Also, the 1% withholding deducted from marketplace payouts is NOT A COST — it is offset against income or corporate tax; recording it as an expense in pricing understates your margin.

FROM ABROAD: If you are established in the US, the transaction is a domestic sale and that country’s tax regime applies; micro export rules do not. In either case applications go through eBay’s own seller channel and the marketplace sets the acceptance criteria. Requirements change by country and over time, so no fixed document list is given here — confirm current requirements on the eBay seller page. On the integration side there is no difference: wherever the store was opened, it connects with the same credentials.

Frequently asked questions

How many credentials does eBay integration require?

Three: an application key, a secret and a refresh token.

Should automation be fully enabled on day one?

Not recommended. Observing a small set of products for a day after the first synchronisation catches barcode and variant matching errors before volume grows.

Can eBay share stock with other marketplaces?

Yes. With a shared stock pool the physical stock is held once and a sale in any store draws from the pool.
