Watch a Bitcoin Address (called by application)

Inserts the address and callbacks in the DB and imports the address to the Watching wallet.

POST http://cyphernode:8888/watch
with body...
{"address":"2N8DcqzfkYi8CkYzvNNS5amoq3SbAcQNXKp","unconfirmedCallbackURL":"192.168.111.233:1111/callback0conf","confirmedCallbackURL":"192.168.111.233:1111/callback1conf"}

}

Un-watch a previously watched Bitcoin Address (called by application)

Updates the watched address row in DB so that callbacks won't be called on tx confirmations for that address.

GET http://cyphernode:8888/unwatch/2N8DcqzfkYi8CkYzvNNS5amoq3SbAcQNXKp

Proxy response:

{
  "event": "unwatch",
    "address": "2N8DcqzfkYi8CkYzvNNS5amoq3SbAcQNXKp"

}

Confirm a Transaction on Watched Address (called by Bitcoin node on transaction confirmations)

Confirms a transaction on an imported address. The Watching Bitcoin node will notify Cyphernode (thanks to walletnotify in bitcoin.conf) by calling this endpoint with txid when a tx is new or updated on an address. If address is still being watched (flag in DB), the corresponding callbacks will be called.

GET http://cyphernode:8888/conf/b081ca7724386f549cf0c16f71db6affeb52ff7a0d9b606fb2e5c43faffd3387

Try missed callbacks (called by proxycronnode, a CRON job that retries if something went wrong)

See cron_docker

Looks in DB for watched addresses, ask the watching Bitcoin node if those addresses got payments, if so it executes the callbacks that would be usually executed when "conf" is called by the node. This is useful if the watching node went down or there was a network glitch when a transaction on a watched address got confirmed.
