1As we understand, push REST method for products update (templar.secoo.product.addOrModify) must be involved for each product. We will share more than 7000 products. Do we have to perform one POST for each product?2.Do you have a batch way to update product information? 3.Same problem with price and stock updates. We see a batch stock update (templar.secoo.stock.batchModify), but nothing for prices.
