Updating prices and stock

​

Reading product data

For routine syncing, don’t always fetch full data for every product. Base offers lighter-weight methods depending on your need:

​

Bulk updates

Use the bulk methods for writing stock and prices, not one call per product:

• updateInventoryProductsStock — up to 1000 products/variants per call.
• updateInventoryProductsPrices — up to 1000 products per call.

Price and stock updates typically run 4–5 times per hour.

​

Stock reservations

If products come from a native Base inventory (not just a read-only feed), confirming an order automatically reduces/reserves the available quantity — even before your ERP has processed it. This reduces the risk of overselling even if your sync is slower. Current availability and reservations are returned by getInventoryProductsStock. The connection to orders is covered in Order basic principles.

​

Product variants

Variants (size, color, etc.) aren’t a separate entity with their own endpoints — they’re part of the getInventoryProductsData response, and are written/updated with the same bulk methods as main products (updateInventoryProductsStock, updateInventoryProductsPrices), just with variant_id set.

​

Multiple price groups via a CSV feed

If you need to sync several price groups from feeds at once, a dedicated CSV feed is more efficient than a separate XML file per group:

• first column: a clear product identifier (Base ID, SKU, or EAN),
• following columns: individual prices for each price group.

Base can import such a feed cyclically, usually once a day (up to three times a day for enterprise accounts).
