[BUG] [SP-API] [Issue] Regression: POST_PRODUCT_PRICING_DATA Feeds failing silently #2852

SP-API Name and Version or Report/Feed Type

POST_PRODUCT_PRICING_DATA Feeds API

Expected Behavior

I expect that when I receive a FEED_PROCESSING_FINISHED notification saying that a feed is DONE, and all of the messages (essentially price updates for listings) are accounted for in messagesAccepted field of the resultFeedDocument, that the price of the listing on Amazon will change.

Current Behavior

My experience is that often times, after receiving confirmation that the feed is complete (status DONE and all messages are accepted), prices are still not updated on Amazon. Sometimes we retry the feed submission multiple times, and Amazon never updates.

When I say Amazon doesn't update, I mean:

  1. Amazon.com doesn't show the price we updated the listing to, even after hours.
  2. The getPricing API doesn't show the new price for the listing.
  3. We do not receive an ANY_OFFER_CHANGED notification for the listing with our price change.

This essentially saying that POST_PRODUCT_PRICING_DATA are failing silently.

I do understand that there are occasions where the SP API falls behind with feed processing (and sometimes there are even larger outages), but this happens 24/7, all day for the sellers that use our SP Application.

This is a lose/lose/lose because:

  1. Our own business (an Amazon repricing tool) loses customers to this issue.
  2. Our customer's (Amazon sellers) loses business because they can't compete on a listing.
  3. Amazon loses as well because the marketplace is not as competitive.

Context/Screenshots

Tickets have been opened with Seller Central support outlining specific instances (we have many every minute).

The context is that we as a Repricing tool, need to know when we actually have successfully updated a price. If it is not when the feed has been successfully processed with a DONE status, and when it says all messages have been accepted, then when is it? Right now we have to check the getPricing API manually to verify a price update has actually been processed in Amazon's backend systems, or wait for an ANY_OFFER_CHANGED notification confirming our price update. Amazon should either:

  1. Fix the issue of dropped price updates, or
  2. Provide us a better mechanism to understand when a pricing update has actually gone through successfully

Some testing we plan on doing ourselves is to check the following:

  1. Do feeds have some undocumented message limit, where some of our messages aren't getting through (getting chopped off)?
  2. Is there some undocumented rate limit for updating listings apart from the feed submission rate limits?
  3. Does JSON_LISTINGS_FEED also have this issue? Would moving to the JSON_LISTINGS_FEED solve this issue?

Your Environment

We have a hybrid MWS/SP Application. We did not experience this issue when we were using the MWS API, but now this seems to be an issue when we use the SP API for feed submissions.

This is a very old issue that is probably not getting as much attention as it deserves. We encourage you to check if this is still an issue after the latest release and if you find that this is still a problem, please feel free to open a new issue and make a reference to this one.
