I want to prove that a contract was deployed by a specific address (a factory contract). I have noticed that block explorers such as https://etherscan.io/ list the contract creator. How do they get this information? I cant find any way of getting a contracts creators address from the the etherscan api.
How can I identify the address that deployed a contract?

If possible, save the users, transactions and contracts as you send them. This way you don't have to look for them later.
If that's not an option, the long route is to find all the transactions related to the contract address. The first incoming one should be the contract creation transaction, the sender of which is the creator.
