Transactions with the same webOrderLineItemId value but different transactionId

Hello I called the 'Get Transaction Info' API with Auto-Renewable Subscription product type transactionId.

I received a success response and called the 'Get Transaction History' API with the value 'originalTransactionId'.

The response 'transaction' of the 'Get Transaction History' API that matches the 'webOrderLineItemId' value received through the 'Get Transaction Info' API was found, but the 'transactionId' value was different.

Why is this happening? Which of the two transactions is normal?
