Changelog

November 2026 · Security and error code fixes

• Sessions are now kept per API key. Logging in again with the same key returns the same ApiCode and starts the session period over; different keys do not affect each other's ApiCode.
• Endpoints that take a store, order or product source ID now check that the record belongs to your account. If it does not, you get 10001 for a store, 50006 for an order and 70002 for a product source.
• Product stock, price and name updates return ErrorCode: "70005" when the product is not found; before, ErrorCode was empty. Database errors return 99999.
• SetOrderShipmentInformation: when IntegrationId is omitted it is now looked up from the store correctly. Unsupported marketplaces return 60001.
• SetEinvoiceLink only updates the order in the store given by StoreId.
• UpdateProductQuantityByBarcode no longer fails when CurrencyId is sent; the field is ignored.

November 2026 · New documentation

• The documentation was rewritten from scratch in Turkish and English, based on the endpoints' source code. The 2018 PDF and Word documents were removed.
• Endpoints that were missing from the docs were added: GetOrder, SetOrder, SetOrderNotes, SetOrderDetailStatus, SetOrderDetailInvoiced, SetEinvoiceLink, UpdateProductName, UpdateProductNameByCode, UpdateProductQuantityByBarcode, UpdateProductImagesByCode, SetProductCode, GetProductSummary.
• A Postman collection (Turkish and English), a Postman environment and an OpenAPI 3.0 definition were added: Postman and OpenAPI.
• Endpoint pages got a Try it panel that sends requests from your browser.
• Closed marketplaces (GittiGidiyor and others) were removed from the examples.

October 2026 · Product package

• Product endpoints (Product/* and SetProductSourceProducts) need an active Product package. Accounts without one get 70018. Order endpoints are not affected.

1 July 2025 · DeleteProduct removed

• DeleteProduct was removed and returns HTTP 410. To take a product off sale, use StopProduct or set its stock to 0.
