Guys,

I hope you can help me. Im working on a project and im using https://blockchain.info/api/blockchain_wallet_api. I know that the logic is that you create an address for every customer wherein they can send there payment. My question is how i can identify if the user paid on the created address?

I know the API has a callback but how can identify on what invoice reference it is. Can the blockchain API can send a custom variable for callback? I can see in there documentation Http Callbacks {Custom Parameters} but when you can pass it?

Thanks in advance,

Mike
