Note on Zesa Recharges

Requirements

• A method for Purchasing ZESA Tokens
• It is a ZESA requirement that any purchase must be verified. As such please ensure that you use the checkCustomerDetail() method

    final result = await api.checkZesaCustomer(meterNumber);

    // check response status
    if (result.rechargeResponse == RechargeResponse.SUCCESS) {
        ZesaCustomerDetail details = result.apiResponse;
        var customerInfo = details.customerInfo;

        // prompt for user to verify info obtained from api
        zesaUserPromptDialog(message: customerInfo.customerName);
    }

    // there was a problem
    else {
      showSnackbar(message: 'failed to check zesa user: ${result.message}');
    }

• and prompt the customer to confirm the details before calling this method (api.rechargeZesa(...)).
• There is a new transaction state specifically for ZESA that is Pending verification indicated by reply code 4 (RechargeResponse.PENDING). Transactions in this state can result in successful transactions after a period of time once ZESA complete transaction.
• You must call Query ZESA method (api.queryZesaTransaction(...)) periodically until a permanent resolution of the transaction occurs. This polling of a pending transaction should not exceed more that 4 request a minute. Resending of transactions that have not yet failed can result in the duplication of transaction and lose of funds.
• Please note ZESA does not allow refunds so the cost of any errors cannot be recovered.
