This chapter describes the API that the GNU Taler demonstrator bank offers to access accounts.
This API differes from the “Bank Integration API” in that it provides advanced API access to accounts, as opposed to enabling wallets to withdraw with an better user experience (“tight integration”).
The following endpoints require HTTP “Basic” authentication with the account name and account password, at least in the GNU Taler demo bank implementation.
GET ${BANK_API_BASE_URL}/accounts/${account_name}/balance¶Request the current balance of an account.
Response
Details
interface BankAccountBalanceResponse {
// Amount with plus or minus sign, representing the current
// available account balance.
balance: SignedAmount;
}
POST ${BANK_API_BASE_URL}/accounts/${account_name}/withdrawals¶Create a withdrawal operation, resulting in a taler://withdraw URI.
Request
interface BankAccountCreateWithdrawalRequest {
// Amount to withdraw
amount: Amount;
}
Response
interface BankAccountCreateWithdrawalResponse {
// ID of the withdrawal, can be used to view/modify the withdrawal operation
withdrawal_id: string;
// URI that can be passed to the wallet to initiate the withdrawal
taler_withdraw_uri: string;
}
GET ${BANK_API_BASE_URL}/accounts/${account_name}/withdrawals/${withdrawal_id}¶Query the status of a withdrawal operation
Response

// both confirmation_done is true and selection_done is true.
confirmation_done: boolean;

selection_done: boolean;
// Reserve public key selected by the exchange,
// only non-null if selection_done is 'true'
selected_reserve_pub: string | null;

// only non-null if selection_done is 'true'
selected_exchange_account: string | null;
