Use the Availability Feed to update product availability and pricing without reprocessing the full Item Feed.

The Availability Feed is a lightweight alternative to the full Item Feed for high-frequency updates. Use it when updating the main Item Feed regularly is not practical because of file size, server load, or other technical limitations.

This feed lets you sync fast-changing data, such as stock status and current price, without regenerating your entire product catalog.

Use this feed to:

Update stock status in near real-time.
Reflect flash sales or price changes quickly.
Reduce bandwidth and processing by sending only essential fields.

Technical Guidelines

ID Consistency: The <id> field is the primary key. If the ID in this feed does not exist in the main Item Feed, the system will not be able to apply the updates.
Frequency: Run this feed as often as your catalogue size and feed generation process allow. Larger catalogues usually take longer to generate and process, and we aim to provide the best possible processing speed based on your catalogue size and feed generation performance.
