Question about PAN-European FBA integration with prep centre

Fulfilment By Amazon Pan EU and EFN

Hello,

I’m currently in talks with a prep center, and they’ve switched to using the Ysell platform. They’re now requesting API access through a new Amazon developer.

Up until this point, we’ve been getting return data in an Excel format, which includes FNSKU, ASIN, or EAN, along with the corresponding units.

  1. What are your thoughts on this change?
  2. Apart from returns and shipments, what other information will they be able to access in my account? (For context, we send products to Amazon FBA both from our warehouse and from the prep center’s warehouse.)

When you connect any third-party service or application to your Seller Central account, it will inform you about the specific data and functionalities it will have access to.
