Get Transaction Status

[Tranduy1dol]

Hi, If i have a transaction hash, and an account who does this transaction, how can i check that if this transaction is finalized or not?

You can call the Aptos fullnode API, /transactions/by_hash/{txn_hash} GET.

From the response,
If the type field is user_transaction and the success field is true, the transaction is finalized and succeeded.
If the type field is user_transaction and the success field is false, the transaction is finalized but failed.
If the type field is pending_transaction, the transaction is not yet finalized.

Alternatively, you can use the aptos typescript sdk which calls the fullnode API internally:

• getTransactionByHash - to get transaction info
• isPendingTransaction - to check whether the transaction is pending

I'm coding rust, is there any method to get transaction info like typescript sdk.
Thank's for your answer.

If you're using Rust, you can use aptos-rest-client crate like: example1 & example2 and use this function. this will call the same API internally.

I decided to use the wait_for_transaction function. Maybe the original code of Aptos Core is complicated, so I want to see what kind of result this function returns. Does it return a status code, such as 1 for a successful transaction and 0 for a failed transaction?
So does this code work?

    async fn verify_inclusion(&self, external_id: &str) -> color_eyre::Result<DaVerificationStatus> {
        let client = self.client.clone();
        let txn_hash: PendingTransaction = external_id.parse().unwrap();
        let txn_response = client.wait_for_transaction(&txn_hash);
        match txn_response {
            None => Ok(DaVerificationStatus::Pending),
            Some(receipt) => match receipt.status_code {
                Some(status) if status == 1  => Ok(DaVerificationStatus::Verified),
                _ => Ok(DaVerificationStatus::Rejected),
            }
        }
    }
