Title: blockchain.info api - how to determine if callback is valid. Post by: ytwg on April 09, 2013, 08:01:07 AM Hi, does anyone else use the blockchain.info api?
If so how do you determine that the callback is from them. I used to use gethostbynamel("blockchain.info"); but then they changed the callback IP to one not in that list [185.7.149.10]. Yesterday they seem to have changed it again to [91.223.16.20]. Any idea how i can do this automatically without having to log their IPs and when a customer complains, update the php script?
