what is result in  "txs" field?
i was thinking that it is amount, but then I got confused: even you submit a list of addresses, blockchain gives you info grouped by tx, so if you happen to have two of your addresses in one tx, the result doesn't make sense.
It will correspond to one of the submitted addresses, right?
quite complicated...
as opposed to that blockr would not group info by tx but rather by addresses
example: http://btc.blockr.io/api/v1/address/txs/184vxW7JgzbixCN2ZGvyKLxvEXDevT6gaj,15ByNz4AR2uPEJGDrBAgSQgnrx54mReK11
common tx 7b2228e40906096eefb91724452c7209ffc2b939f941a3311ac940466f1de4b3 appears twice in the output

ok got it called block_height
thanks

but where is the number of confirmations???

ok, sorry I found the problem, this was related to JSON serialization

I want to get latest deposit transactions for multiple addresses
https://blockchain.info/api/blockchain_api
section Multi Address

https://blockchain.info/multiaddr?active=17BAPwLRZq9zpwwEeow9rBwb1TAypkp2jC|1HxYTGPikRDJ6ybKbGjzvmrKbdQiSHh6An
i can't figure out how to group transaction by address (no joke). Such a simple thing took me a couple of hours already. When I look at the list of txs i can't figure out the algorithm that I can detect a new deposit to an address

no issue with blockr, were i can see clearly deposits, because txs are grouped by addresses, but i need blockchain

why moved here? this is not a trading question!
mods, what's up?

the question is if i use one permanent address for each user will there be any security concern?

any danger in reusing deposit address for my web-site users?

I know localbitcoins deposit address is always the same, so is coinbase

it would make tracking much more easier for me

come on this is development discussion

After some research i am inclined to use blockchain.info API and http://blockr.io API

So far the only problem of blockchain.info are delays, so I was thinking to run a perpetual loop and query txn from http://blockr.io API to track customer payments. Then when blockchain.info callback arrives finally this will be like a second confirmation

I don't want to run my own bitcoin server because people are getting hacked...

am i doing it right?
ideas anybody?

I want to accept payments myself and I want to detect transaction immediately like coinbase does. But for the moment I plan to keep funds at blockchain.info
Currently blockchain.info is slow (delay is 20 min - few days), so I need a faster way to monitor tranactions.
Kind of local blockchain explore.
Any ideas?
I know Abe, but I don't want to install python and also it migrates everything into MySQL
I would prefer direct browser

what does it mean?
how can i do it via API?

damn it the file size was 0  
ok started

now how can i get a balance of some address that is not in my wallet?

If I need to monitor thousands of wallets, how can I do it?

I want to be able to notify a user immediately of a payment

looks like bitcoin core can tell the balance only of local wallet. Kinda strange

but looks like you will have to keep all your customers' wallets on the server, because bitcoin core does not support watch only wallets. Kinda strange, because if you have all blockchain why not to allow to peek at a wallet balance like block explorer or blockchain.info does? I want to be able to notify a user immediately of his payment, I don't care if he double-spend, I can deal with it later

I was thinking to have user's wallets as cold and just watch them, but now I am rethinking...

so how do you use it? can you please explain or point to some tutorials?

when I run
bitcoind -daemon
it tells me "this app can't run on your PC"

and if I run
bitcoin-cli listreceivedbyaccount 1XXXXXXXXXXXXXXXXXXXXXX

it tells me
error: couldn't connect to server

Blockchain.info receiving API has been two weeks of total disaster. Few hours to few days delays.

I am looking at alternatives currently and thinking to run my own server with bitcoind

currently stuck with running on Windows Server 2012 x64 see my other post

After blockchain.info API 2 week outage, I've decided to try running bitcoind and monitoring accounts myself. I want users to pay and instantly know that payment was received.

I installed bitcoin core on Windows Server 2012 x64 (Azure) and tried
bitcoind listreceivedbyaccount xxxxxxxxxxxxxxxxxxx -rpcuser=xxxx -rpcpassword=xxxxxxx

but there was a system message "this app can't run on your PC"

I was planning to use https://github.com/GeorgeKimionis/BitcoinLib

When I run Cosole app, I get the same "this app can't run on your PC" message

Any ideas?

two last weeks is terrible, waiting for several hours or days for funds to be forwarded and a callback for a confirmation

i am looking for alternatives

I have submitted a ticket and they are looking into it.

btc forward and callback now takes 15 to 30 min 10 hours and callback also comes after even longer period

i bet a lot of people need that type of service

edit: it is very unstable now. minimum what I see is half an hour, sucks...
