user29597: Is there any way to watch all addresses under HD wallet?
I'd like to notify users when any of addresses in a HD wallet receive BTC.

It looks like bitcoind (walletnotify) doesn't support HD wallet. You have to add many addresses into a wallet to watch them.
blockchain.info xpub API? (I'm not sure how the API can handle it.)


It seems there is no web service for watch-only HD wallet. Is there any web-service to watch(only) HD Wallet BIP32? : Bitcoin

Actually there is. Check out blockonomics , it supports xpub search and also wallet watcher with xpub support that sends out email notifications on transactions.  Also has websocket API for notfications

We have a series of HD Wallet Endpoints that we recently released that might suit your needs; you can read more about it here:

You can use it in tandem with our WebHooks API for notifications whenever an address associated with an HD wallet is involved in a transaction.
If you want to use something locally instead of our API, I'm a fan of btcd and their associated btcwallet, which supports HD addresses.
