understand the flow for new inbound/fba/2024-03-20/inboundPlans

Hi Sellers,

I'm trying to understand the correct workflow for creating FBA shipments using the new SP-API endpoint (inbound/fba/2024-03-20/inboundPlans). I have some specific questions about handling used products via FBA.

Previous Workflow (V0):

- Could directly pass ASIN and custom SKU to create inbound plan

- No pre-listing requirement

- Simple workflow for used/new items

Example V0 payload (simplified):

{

"sku": "MY-USED-BOOK-01",

"asin": "B000123456",

"condition": "Used - Very Good",

"quantity": 1

// other fields...

}

Current Challenges (2024-03-20 API):

1. New API only accepts MSKU, no ASIN field in the payload

2. Getting error: "MSKUs are not valid" when trying to create plan

3. Documentation doesn't clearly explain the pre-requisites

Example new API payload:

{

"destinationMarketplaces": ["ATVPDKIKX0DER"],

"items": [

{

"labelOwner": "SELLER",

"msku": "MY-USED-BOOK-01",

"prepOwner": "NONE",

"quantity": 1

}

],

// address and other fields...

}

Questions:

1. What's the correct sequence of API calls to list a used item for FBA?

2. Do we need to create a catalog listing first? If yes, which API endpoint?

3. Is there a waiting period between listing and creating inbound plan?

4. How do we specify the condition (Used - Very Good, etc.) in the new workflow?

If anyone has successfully implemented this new workflow, I'd really appreciate:

- The sequence of API calls needed

- Sample payloads that work

- Any timing considerations between steps

- Best practices for handling used inventory

Thanks in advance for any help or insights!
