Frequently Asked Questions
Do you need assistance in hiring Amazon MWS/SP-API developers? Our team at Inter-Soft includes skilled specialists who are ready to discuss your project requirements and help you find the perfect expert to fulfill your needs. For further details, please contact us through our contact form or directly via our agency.
The integration process will remain the same, and all MWS developers will be able to seamlessly transition to SP-API. You can contact us for further assistance and more information about integrating with the new SP-API using your existing MWS credentials.
Amazon Seller Partner API (SP-API) offers a range of improvements compared to MWS. It adopts modern, JSON-based REST API design standards and enables selling partner authorization using “login with Amazon”. Additionally, it fulfills the most requested feature in MWS by providing a test endpoint. Going forward, all new API functionalities will be built in SP-API, while MWS will only receive updates to support critical business changes.
The migration from MWS to SP-API is not currently mandatory. However, it is highly recommended to explore the benefits and improvements of SP-API integration to enhance your business operations. While there is no specific deadline for migration, it is advisable to start planning your transfer to SP-API to take advantage of its enhanced capabilities. For more information and assistance, feel free to reach out to our experts.
