How to get more information on didSynchronizeTransaction()

Hello, Let's say I make three transactions offline. When I get connectivity back, the SDK automatically sync the three transactions and I receive data in the callback with didSynchronizeTransaction(). However, I only get a GUID but I don't know which of the three transactions is has been synced. In our case, it is really important to know what transaction has been synced to the servers so we can make some procedures afterwards. Is there a way to get more data of the transaction that was just synchronized ? Imagine if we do 10 to 20 transactions in a day, all offline, and then the morning after we sync all theses contracts, that would be really tricky to hope that everything syncs in the same order as it has been created. Hope the question is clear enough :)

Hi there, I think you were asking how you can map the temporary package ID to the actual synchronized package ID, so that you know which package has been synchronized and safe to notify to your backend. If that's the case, because the OSS Mobile SDK synchronize queue cleared/synchronized the cached transactions one by one, it should be safe to consider the temporary ID returned in "didStartTransactionSynchronization" callback(D5E6243D-587D-418E-B90A-56EBF76AD656 below) matches the actual package ID returned in "didSynchronizeTransaction" callback (PioIYmNRiN11-ARBNFmjU02K29g= below). Below printed console log represents my test case -- created two transactions offline, then turn on wifi
