Checking for confirmations using getrawtransaction and decoderawtransaction

I am trying to check if a transaction is confirmed or not via RPC commands. At first I tried to use gettransaction, but it doesn't work.

Then I use getrawtransaction and decode it:

{
   "lock_time":0,
   "size":192,
   "inputs":[
      {
         "prev_out":{
            "index":1,
            "hash":"5352d8186b825128a7d4a0df0a8c105da70c81ec763209271566a512fee14cee"
         },
         "script":"483045022100fae0b1dbe08f79a92debde8f3a8e955bcff9ce928b86fb217cfd830af6937386022072386b28a288408bad05426704b55f14a4ad4bf3927ac053facda4478c467eae0121034756f0f954f40ed7dabcaa80c4212a240e4b2c1eee7532bd06cac58c173faf3f"
      }
   ],
   "version":1,
   "vin_sz":1,
   "hash":"931d220f622a9b029cea3e09ca7a9c11f3714c68f9bd272ca97cd915b518050d",
   "vout_sz":1,
   "out":[
      {
         "script_string":"OP_DUP OP_HASH160 0f14a815e42dcdff9c8239a7393b2a9a63a8b68d OP_EQUALVERIFY OP_CHECKSIG",
         "address":"12Njt85fc9Kr7s8tr3Eug4tvkZQUhcGXfz",
         "value":100000000,
         "script":"76a9140f14a815e42dcdff9c8239a7393b2a9a63a8b68d88ac"
      }
   ]
}

And I got the above result. But I don't understand what is written, how can I know if it has been confirmed without relying on Blockexplorer?

Thanks

The decoderawtransaction RPC call oddly omits the confirmations field in the resulting JSON output. Instead of using decoderawtransaction, try this:

$ bitcoin-cli getrawtransaction <tx_id> true

(Notice the "true" at the end, which means "output as json")

This will return JSON that has a "confirmations" field in the top level of the returned object.

hi thanks for the reply... but i am getting Error: value is type bool, expected int – OneyesOneno – 2018-01-25T10:54:28.747

@OneyesOneno ah sorry, we might be on different versions. try: bitcoin-cli getrawtransaction &lt;tx_id&gt; 1 – Tony Rizko – 2018-01-25T11:07:35.983

hii... its me again.. i try 1 , it return  parameter 1 must be hexadecimal string (not '04e66db5c1dc6471c6e518636ed66f99cbb853a2bb3303cd0a60403d49e66a4') (code -8) .. then it try getrawtransaction (tx_id) verbose = it return Error: Error parsing JSON:verbose – OneyesOneno – 2018-01-25T12:02:47.583

hi @OneyesOneno, it looks like the hex string you are providing is invalid: (04e66db5c1dc6471c6e518636ed66f99cbb853a2bb3303cd0a60403d49e‌​66a4). You are missing 3 more hex digits. – Tony Rizko – 2018-01-25T20:10:40.723

wow you are absolutely right about it. Thanks you so much! – OneyesOneno – 2018-01-26T01:15:00.910
