Update product price (by ProductId)

Updates the prices of the product found by ProductId and, optionally, of its variants.

POST https://out.stockmount.com/api/Product/UpdateProductPrice

Changes data Product package required

Each call updates a single product; you cannot send several products in one call. You can update several variants of that product in the same call with Variants.

The product is identified only by ProductId. To update by product code, use the ByCode endpoint.

Price, MarketPrice and Price2–Price5 are overwritten on every call with the values in the request; any field you omit becomes 0. Send every price you use each time.

Each item in Variants is matched to the product's variants by ProductVariantId, or by variant Code when no ID is given. A matched variant gets its Price and Price2–Price5 replaced by the request values (omitted ones become 0). Variants not in the list are not touched. A variant-level CurrencyId is not read; the product-level CurrencyId is used.

This endpoint does not validate prices: 0, negative values, or a MarketPrice lower than Price are accepted. Such problems surface as errors during marketplace synchronization, not in this call.

This endpoint does not change stock or name; Quantity and Name are ignored.

The price is written to the product in StockMount first. If any price actually changed, a price update is queued for each active marketplace listing of the product. Marketplaces are updated by background jobs, not during this call. If an update of the same kind is already pending, no duplicate is queued.

If the product is not found or does not belong to your account, the response is Result: false with ErrorCode: "70005" and ErrorMessage: "ProductNotFound". Database errors return ErrorCode 99999.

Accounts without an active Product package get error 70018; if the package cannot be verified, 99999 is returned.
