Were you surprised by Amazon’s migration from Marketplace Web Services to the Selling Partner API? We can help.

As of Aug 31, 2023, the Merchant Fulfillment (MFN) API, Orders API and Reports API are no longer available on Marketplace Web Services (MWS). From March 2024, all other MWS APIs, including the Products API, will follow. Unfortunately, we’ve spoken with a number of Amazon sellers with “homegrown” integrations that weren’t ready, only noticing when their orders broke.

ChannelAdvisor has hundreds of engineers that reliably deploy code on an hourly basis — integrate once to us and we’ll handle the API updates for you.
