How to get notification on bitcoin receive with bitcoin core How can I get Bitcoin receive notifications with Bitcoin Core. I have tried the walletnotify and blocknotify options. walletnotify is fired two times when I send or receive bitcoins. And with blocknotify I have to perform below task to detect which account of the wallet has received bitcoin.


Run getBlock command to get all transaction hash
Run a for loop for each transaction hash to run getTransaction command
If transaction hash belong to my wallet account, I save the receive transaction in my database. 


Using blocknotify seems to be inefficient as it involves lots of RPC calls per transaction.

walletnofity executes twice for bitcoin send and receive.

I have also tried ZMQ but I got a response which is difficult to convert into desirable format.

So could anybody suggest some efficient way to get a bitcoin receive notification upon first confirmation?
walletnotify executes once per every unconfirmed transaction creation (incoming/outgoing) and once more once the transaction is mined into a block (gets it's first confirmation).

I am not sure what are you developing, but as far as I see it both notifications are essential:
The first one to let the customer know that his transaction had been recorded, and the second to know that the value was indeed remitted, with enough fee, and will not be double spent.
