getaccountaddress (Deprecated, will be removed in V0.18. To use this command, start bitcoind with -deprecatedrpc=accounts)

The getaccountaddress RPC returns the current Bitcoin address for receiving payments to this account. If the account doesn't exist, it creates both the account and a new address for receiving payment. Once a payment has been received to an address, future calls to this RPC for the same account will return a different address.
