How can we determine whether the following two transactions are successful or failed?

[a402942988]

Could you please explain how these two transactions are judged as successful or failed? Is it based on a specific field?

Successful transaction: https://testnet.toncenter.com/api/v3/transactions?hash=7dd1395e2a517a7f91e7369d2554db817121950260b7f3d0b9e753582a57b58b

Failed transaction: https://testnet.toncenter.com/api/v3/transactions?hash=c85c583116e45d76214ca3581de4dc804cd6317efda8152a122641ea55aa792c

from toncenter perspective these look like successful transactions, however, in tonviewer it shows that the second one has failed:
https://testnet.tonviewer.com/transaction/aa3164253416c856aff6468a18c7eefaa3e8eb58cc16a9fc3da48eeefed6752f
you have to refer to right tx hash in toncenter, which is aa3164253416c856aff6468a18c7eefaa3e8eb58cc16a9fc3da48eeefed6752f

I have a transaction hash, but I don't know how to determine whether the transaction was successful. Using the Toncenter V2 JSON-RPC API makes it even more unclear, as it doesn't seem to have a field indicating whether the transaction was successful or failed.

Additionally, I noticed that in the V2 API, the following request does not seem to apply the transaction hash parameter correctly. Instead of returning the specific transaction, it always returns a paginated list of all transactions under the specified user. Could you please provide some guidance? Thanks!
