Updates the price and promotions in bulk for multiple items. You can modify the prices of multiple items in bulk using a price feed. This is useful for implementing pricing strategies across your catalog, such as seasonal discounts, competitive pricing adjustments, or clearance sales.
Each price feed can contain up to 10,000 items. To ensure optimal performance (feed processing time), we recommend limiting the feeds to 1,000 items and keeping the payload under 10 MB.
The price sequence guarantee is observed by the bulk price update functionality, subject to the following rules:
Use this API instead of the single price update API, especially if a new item has been set up and a Walmart Part ID (wpid) is available. Ensure to wait at least 24 hours after item creation to use the bulk price update API. The bulk price update Service Level Agreement (SLA) is 15 minutes.
You may include the same Stock Keeping Unit (SKU) multiple times in a single feed. However, if a SKU is repeated in a feed, only on price will be applied. The price sequence guarantee ensures that the latest price update, based on its creation timestamp, is the one that changes the price of the item, overwriting the previous version. Price updates received with an earlier timestamp are ignored. As a result, we recommend all feed-based bulk updates base the value of feedDate on UTC.
After submitting the price feed, wait at least 5 minutes before checking whether the bulk price update was successful. If a price update fails, for example due to duplicate SKU entries, an error response will be returned.
