How to add destination_tag to transaction ?

[prodevcn]

I created transaction and signed it and submitted but method returned response like that :

Identifying hash: 5A924302E53F2FFC52CCF68C93B13E70EC9ED4151D632E6CCC79B917C4EF0DE0 Signed blob: 120000228000000024038EB22B201B0395CA076140000000009896806840000000000017EB7321031D258AE06AE643E8663CA15A1FA5DD2EE211D24D2A7522D5AAFE59A6A11E353B7446304402202592AB0F1CD163A258019BC15C9009E42F078B44A78B488CCFA2CEC3A1AC31570220486B32A63813DBF8C8174653F0311A45CC9E2F20D9B77AC18A76FE1E942B16388114AB68020445C84CC798E76E4D683AA3ED50AD80D48314A025D8B3210251C94FA3AAC92E159673A140FAD9 Tentative result code: tecDST_TAG_NEEDED Tentative result message: A destination tag is required.

How can I add destination_tag to transaction object ?

Hey @block-hac, you will need to specify the destination tag in the Payment Instruction:

const payment = {
  source: {
    address: sourceAddress,
    maxAmount: {
      value: '0.01',
      currency: 'XRP'
    }
  },
  destination: {
    address: paymentDestinationAddress,
    amount: {
      value: '0.01',
      currency: 'XRP'
    },
    tag: 12121982
  }
}

Thank you @elmurci I use ripple-lib api and source code is as follow :

api.connect()
        .then( () => {
            return api.prepareTransaction({
                "TransactionType": 'Payment',
                "Account": req.body.fromaddress,
                "Amount": api.xrpToDrops(req.body.amount),
                "Destination": req.body.toaddress
            }, {maxLedgerVersionOffset: 75}).then( async (preparedTx) => {
                const maxLedgerVersion = preparedTx.instructions.maxLedgerVersion;
                console.log("Prepared transaction instructions:", preparedTx.txJSON);
                console.log("Transaction cost:", preparedTx.instructions.fee, "XRP");
                console.log("Transaction expires after ledger:", maxLedgerVersion);
                const txJSON = preparedTx.txJSON;
                const response = api.sign(txJSON, req.body.secret);
                const txID = response.id;
                console.log("Identifying hash:", txID);
                const txBlob = response.signedTransaction;
                console.log("Signed blob:", txBlob);
                const latestLedgerVersion = await api.getLedgerVersion();
                api.submit(txBlob).then(async (result) => {
                    console.log("Tentative result code:", result.resultCode);
                    console.log("Tentative result message:", result.resultMessage);
                    res.send(result);
                }).catch(err => {console.error(err)});
            }).catch(err => {console.error(err)});
        })
        .catch(err => {
            res.send(err);
        })

I'd use preparePayment for this. If you look at the Payment type you can see the you can use a destination.tag.

@block-hac You can add the DestinationTag field to the transaction JSON:

{
                "TransactionType": 'Payment',
                "Account": req.body.fromaddress,
                "Amount": api.xrpToDrops(req.body.amount),
                "Destination": req.body.toaddress,
                "DestinationTag": destination_tag
}

Be sure to replace destination_tag with the destination tag that you wish to use!

thanks @intelliot I already tried it but it returned error message.

@block-hac DestinationTag must be a number. Try removing the "quotes" around the number. Just use "DestinationTag": 106018755 instead.

Thanks @intelliot , I just found that.

Are you happy to close this issue @block-hac?
