How to get the inboundPlanId & shipmendId for old shipments when you only have the FBAXXXXXX ID?

[MetaMan2023]

Problem:

The new inbound API requires inboundPlanId and shipmentId for current operations.

If we only have an FBA ID (FBAXXXXXXXX), what call can we make to get the inboundPlanId and shipmentId to make those calls?

We have some old shipments that were made with v0 API and we did not need, have or store that information -- but now we need it for certain record keeping and tracking of shipments from the past 3-6 months.

Hi,
You can call https://developer-docs.amazon.com/sp-api/docs/fulfillment-inbound-api-v2024-03-20-reference#getinboundplan to get all the associated IDs.

As I noted in my original question -- "getInboundPlan" requires the "inboundPlanId" as an input. I don't have the inboundPlanId for many shipments prior to late January 2025 (when the new API was forced over).

Please advise how I get an "inboundPlanId" from a "FBA_________" format shipment ID from the older system.
