Migration FAQ
SP-API Migration Frequently Asked Questions
This FAQ covers questions that developers may encounter when migrating from Amazon Marketplace Web Service (MWS) to Selling Partner API (SP-API). Answers may vary depending on your application as well as whether the app is private or public.
General migration topics
When is Amazon MWS going away?
Select to expand the answer.
MWS will no longer be available for use after March 31, 2024. Amazon has chosen a phased deprecation for Amazon MWS, and we have publicly announced migration due dates for both third-party public app developers and private app developers.
Why is Amazon replacing MWS with SP-API?
Select to expand the answer.
SP-API offers all developers a number of improvements over Amazon MWS, such as modernized, JSON-based REST API design standards, OAuth2.0 selling partner authorization using Login with Amazon, and a test endpoint - the most requested feature in MWS. In addition to all legacy functionality previously provided in Amazon MWS and new API capabilities for sellers, SP-API supports the first ever APIs for Amazon vendors – all through the same API control plane and authorization mechanisms. Going forward all new API functionality will be built in SP-API, with updates to MWS only to support business critical changes until MWS is deprecated. Having all developers integrated with SP-API will provide the best experience for both Selling Partners and developers.
Where can I learn more about SP-API?

Private developers select to expand the answer.
If you have a private Amazon MWS Developer ID and Access Keys that call the Merchant Fulfillment (MFN), Orders, or Reports API sections, then you must create and operate a private Selling Partner app to integrate these sections. This must be completed by August 31, 2023.

Apps are listed in my Manage your apps section. What action do I need to take?
Select to expand the answer.
The applications shown in this section are third-party public applications that you have authorized to access your selling information to support your business automation needs.

Important
- Submitting an extension request does not guarantee an approval. Requests are evaluated on a case by case basis and may be denied or partially approved.
- Extension requests should only be submitted one time. Carefully evaluate the time period for which you will request the extension, and assess the actions you can realistically complete during this time frame.
- If you have multiple MWS accounts, you only need to submit one extension request form. If you have multiple Amazon accounts with MWS Developer IDs associated to your business that this request should also apply to, you can include those additional Developer IDs within the form.
My account lost access to data from the MWS Merchant Fulfillment API, Orders API, and Reports API sections as a result of the August 31 migration due date. Can I appeal this to regain access?
Select to expand the answer.
If you were not able to complete your migration to SP-API for these sections and need more time to migrate, you have until October 1, 2023 to submit an extension request to temporarily regain access to these sections.

Why did I receive an error message saying my account is ineligible for a migration extension?
Select to expand the answer.
If you receive this error message when trying to submit an extension request, the seller account you are using to submit the request falls under one of the following categories:
-
MWS credentials for this account may have been deactivated due to inactivity in accordance with the Acceptable Use Policy.
-
The account has MWS credentials, but is not able to retrieve data from MWS as it does not have active MWS self-authorization in accordance with the Acceptable Use Policy.
-
The account only uses the MWS Reports API to get Amazon Pay and Amazon Pay related reports, and is not required to migrate to SP-API. Amazon Pay users will not be affected by MWS access removal after the August 31, 2023 migration due date. If you access Amazon Pay reports via the MWS Reports API today, you must migrate to the new Amazon Pay Reports API. For detailed instructions, refer to Migrate from MWS Reports.
If you have another Amazon seller account with active MWS credentials assigned for which you would like a migration timeline extension, you must log in to that account to submit this form.
To find MWS credentials assigned to your seller account, log in to Seller Central and navigate to Developer Central.
If you need access to data for Merchant Fulfillment, Orders, and/or Reports functionalities, you can authorize a third-party app from the Selling Partner Appstore, develop an app with SP-API, or use data from Seller Central.
I use Amazon Merchant Transport Utility (AMTU). Can I request an extension to use it after August 31, 2023?
Select to expand the answer.
No, after August 31, 2023, the AMTU tool will be deprecated. AMTU/Listing Loader will maintain access to MWS for all functionality until August 31, 2023. More information is available on the AMTU Help Page.
To avoid any impact to your business, you can substitute the functions using AMTU by authorizing a third-party app from the Selling Partner Appstore, developing your own SP-API app, or using data on Seller Central.
Can I submit an extension request for the migration of MWS API sections due on March 31, 2024?
Select to expand the answer.
No, we are not evaluating extension requests for this due date. We will post an update if this becomes available in the future.
I submitted an extension request, but it was denied or not approved for the time I requested. What should I do?
Select to expand the answer.
All cases are evaluated on a case by case basis based on the information provided. Your business should plan accordingly for the due date provided in the case response. If you feel there was information missing from your original request, do not open a new case. You may comment on your existing extension request case within five days to provide this information, however there is no guarantee of a different outcome, and multiple requests may be denied.
