App Store Server API: both transaction history and lookup customer order id return 404

Question

We can get a customer’s transaction history through this (API)[https://developer.apple.com/documentation/appstoreserverapi/get_transaction_history]

https://api.storekit.itunes.apple.com/inApps/v1/history/{transactionid}

and get purchase transactions through the customer order id per wwdc21

https://api.storekit.itunes.apple.com/inApps/v1/lookup/customer_order_id

However, we got 404 with an empty response body for those two APIs and the curl response is

* Connection state changed (MAX_CONCURRENT_STREAMS updated)!

How to debug this issue or anything am I missing?

Update

This API inApps/v1/lookup will be released per app store guys this year.

Answer 1

It seems that this API is only available in the sandbox environment for now:

That's why you have a generic 404 error without any response's body I suppose.
