blockchain.info api (Balance Updates [POST]) confirmations not received I'm trying to use "Balance Updates [POST] Monitor addresses for received and spent payments" from https://blockchain.info/api/api_receive 

I subscribe to an address and get the response:

{
  "id": 15108,
  "addr": "1P9RQEr2XeE3PEb44ZE35sfZRRW1JHU8qx",
  "op": "ALL",
  "confs": 3,
  "callback": "https://d83bb66d.ngrok.io/bitcoin/confirmations",
  "onNotification": "DELETE"
}


then with each new transaction I get a notification with 0 confirmations, that looks like this:

{ 
   "address" : "1P9RQEr2XeE3PEb44ZE35sfZRRW1JHU8qx", 
   "confirmations" : 0, 
   "transaction_hash" : "38dbb8083a8c3006eae6c1194789941943cb60201ebfb03963188d4eb1d01d23", 
   "value" : -9030800 
 }


but I never get a notification with the 3rd confirmation


  confs - Optional (Default 3). The number of confirmations the transaction needs to have before a notification is sent.


I tried setting confs to 1, 2 and leaving it as default, but I never get any confirmations, I have tried with different addresses, right now the transaction in this message has 5 confirmations but I didn't get any notification.

does any one know what's wrong ?

thanks
You need to set onNotification to KEEP, otherwise all future notifications such as those for confirmation number will not be sent.

From the docs:


  You are required to specify the request's notification behaviour. Setting the behaviour to 'DELETE' will delete the request after the first relelvant notification is sent to your callback address. Setting the behaviour to 'KEEP' will send additional notifications every time a transaction with the specified confirmations and operation type is sent to or from the address in the request.
