Missing Parameter Password

Making transactions to/from the new wallet

The address returned in a successful response message can be used to deposit funds into the wallet.

It is possible to send payments from the wallet by providing the guid and password to the blockchain wallet api. However this is not recommended as if the wallet password is changed or two factor authentication is enabled you will no longer be to access the wallet.

Instead the recommended way to send payments is to provide a private key to the create_wallet method. A copy of this private key can be stored in order to send and receive payments from that specific address in the wallet. You can pass the private key directly to the blockchain wallet api instead of using the identifier and password.
