Personal Bitcoin Address

If you use Electrum wallet – new address is generated for each new customer. This new generated address always belongs to your electrum wallet.
You just need to make sure to set high enough “gap value”, like 100 or even 500 so Electrum wallet’s balance check will “cover” that new address.

If you use Blockchain.info API – blockchain will generate new address that belongs to blockchain. If customer sends payment to that address – blockchain will eventually forward it to your address. This process could take a while though.

Using Electrum wallet as a payment option is faster and more secure.
