On June 23, 2025, Amazon announced a major update through their official developer communication: legacy Listings Feeds, including commonly used XML and flat-file formats, will be officially retired on July 31, 2025. This means any seller still using those older methods to update product listings on Amazon must switch to the modern Listings API to avoid disruptions.
If you’re an Amazon seller, or if your software provider hasn’t yet transitioned to Amazon’s SP-API framework, your ability to manage or update listings may be affected. Listings feeds have long been a core part of how sellers push product data to Amazon in bulk. From flat file templates for FBA product creation to automated inventory and pricing updates, these feeds have powered a large portion of third-party listings on the platform. However, Amazon is modernizing this system by moving fully toward JSON-based APIs that offer faster processing, better error handling, and improved data accuracy.
What Are Listings Feeds?
Listings feeds are the structured file formats (like XML or tab-delimited .txt files) sellers or software use to submit large batches of product data to Amazon. They’ve been a go-to method for years—but they’re now being phased out.
Feeds affected include:
POST_PRODUCT_DATA
POST_PRODUCT_PRICING_DATA
POST_INVENTORY_AVAILABILITY_DATA
POST_FLAT_FILE_LISTINGS_DATA
POST_PRODUCT_IMAGE_DATA
Starting July 15, 2025, these feeds may start processing slower. After July 31, 2025, they’ll no longer work at all.
This change will impact a wide range of sellers—including those doing FBA, FBM, and wholesale. If you’re relying on inventory sync tools, listing automation platforms, or even your own custom-built upload systems that still use XML or .txt files, now is the time to assess and upgrade. Amazon noted that by July 15, 2025, you may already start to experience slower processing times when submitting feeds. After July 31, these legacy formats will be fully disabled and no longer accepted.
What You Should Do
For sellers managing their own systems, Amazon recommends transitioning to either the Listings Items API or submitting data using the newer JSON_LISTINGS_FEED. These tools are part of the broader Selling Partner API (SP-API) ecosystem, which provides more robust functionality and aligns with Amazon’s push toward modern infrastructure. If you’re using a third-party listing tool, it’s important to reach out to your provider and ask if they will support the Listings API before the deadline. If they aren’t prepared, you may want to consider alternative solutions, or reach out to a fulfillment partner like Proven Prep that can help ensure continuity.
For Sellers Using Custom Integrations:
You need to migrate to Amazon’s Selling Partner API (SP-API), specifically:
The Listings Items API, or
The new JSON_LISTINGS_FEED
These are modern, more robust interfaces that use JSON instead of flat files and offer better validation and control.
For Sellers Using Third-Party Software:
Ask your software provider: “Will you be upgrading to Amazon’s Listings API before July 31?”
Why Amazon Is Making the Change
Amazon’s motivation behind this shift is clear: the new Listings API allows for faster updates, more reliable submissions, and better control over product content. It also simplifies troubleshooting, since error messages returned via the API are more precise and actionable than those in flat-file responses. Ultimately, it aligns with Amazon’s broader goal to modernize and unify systems under SP-API.
