I think I can keep calling by etherscan to find new transactions and I the best way is that I can receive a url callback once an event created on erc20 token event log. Any API I can use for this? Or I must keep calling etherscan API for doing this? Thanks


Both geth and parity support Log filters. You can easily run a node and subscribe to the Transfer event for tokens you care about (or all Transfer events if you wish), and then pass that information onto whichever system needs it.

eth_newFilter will let you create this filter, and eth_getFilterChanges will let you receive updates.


Cindercloud has an API which allows you to do this. Internally,it uses geth and parity filters, but provides you with readable data.
