node package manager



This is a command-line script that downloads transactions and balances from financial institutions using Zombie.js. Currently supported banks:


Install Node.js, then:

sudo npm install -g banker
banker --help


banker --config config.json --output data/results.json

Running banker --help shows documentation for other command-line options:

Usage: banker options
  -b, --banks          Just list the banks that this program can download
                       information from.
  -l, --list           Just list the banks and accounts in the given config
  --describe-output    Just list the banks and accounts in the given output
  -c, --config         The JSON config file(s) describing the banks and
                       accounts to process.
  -o, --output         The JSON output file with transaction details.
  -s, --skip           Skip the specified bank(s) or account(s).
  --only               Only process the specified bank(s) or account(s) - see
                       --list for valid specifiers.
  -d, --debug-browser  Save pages fetched by the browser (to the same directory
                       as the output file).
  -v, --verbose        Increase verbosity (up to -vvv).
Config filename is required unless '--banks' is specified.

Note that if you are using the --debug-browser option, you should put the --output file in its own directory, since the program will dump a bunch of HTML pages in the same directory. (The directory will be created if it doesn't exist.)


Create a JSON configuration file (config.json above) that contains a bank configuration or an array of bank configurations. Bank configurations usually need to contain the following items, see the output of banker --banks for exact settings required for a given bank.

  • bankName - the name of the bank. This should be the name of the JavaScript file in lib/banks without the .js extension.

  • username - your online banking username.

  • password - your online banking password.

  • securityQuestions - a hash of security questions and answers, like this:

"securityQuestions" : {
    "What is your favorite color?" : "Black"
  • accounts - a list of account configurations. The required items vary by bank - use the output of banker --banks to determine which fields are required.

    If you are using the --debug-browser option, specify a filename field for each account, and this value will appear in the filenames of the HTML pages the program saves.

    Also, any additional data that you include in the account configurations will appear in the output file, so you can use this to pass identifier fields etc.

See the output of banker --banks or the files in the configs directory for more details about the configuration file.


The program will write a JSON file to the path specified after --output, with the following structure:

    // object for first bank data 
        "bank"   : // bank name 
        "status" : // may contain a message like "skipped" 
        "error"  : // the error message for this bank, if any 
        "data"   : [ // list of data objects, one for each account 
            // account information (copied from config file) 
            "account" : {
                // ... 
            // transactions downloaded from this bank 
            "transactions" : [
                    "date"        : // self-explanatory 
                    "amount"      : // self-explanatory 
                    "description" : // self-explanatory 
                    "memo"        : // like a "sub-description" (if any) 
                    "images"      : /* any images downloaded for this
                                       transaction (encoded as a data: url) */
                    "sourceId"    : /* transaction ID, from bank or
                                       generated from other fields */
                    // (transaction objects may also contain other fields) 
                }, {
                    // ... (more transactions) 
            // balances downloaded from this bank 
            "balances" : {
                "actual"    : // latest posted balance 
                "available" : // available balance 
                "fromList"  : /* balance from transaction list (hint: it's
                                 worth checking if this matches the other
                                 balances since some bank software is buggy) */
    }, {
        // ... (data objects for more banks) 

Adding Banks

To add a new bank, write a driver for it and put it in the lib/banks directory. The filename of the driver will be the string used to specify that bank in a config file.

Drivers should inherit from BankSession (lib/banks/base.js) and should define the following methods: = function() {
    // For documentation, return an object like this: 
    return {
        description  : // Bank description 
        configItems  : // Bank configuration items 
        accountItems : // Configuration items needed for each account 
MyBankSession.prototype.login = function(cb) {
    // Try to log in to the bank website, then call: 
    //  - cb(err)  on failure 
    //  - cb(null) on success 
MyBankSession.prototype.getTransactions = function(accountConfig, cb) {
    // Try to get transactions from the given account, and call cb(err) on 
    // failure or cb(data) on success, where data is an object like this: 
    var data = {
        transactions : // List of transactions downloaded from this bank, in 
                       // the same format as the output file described above 
        balances : // Balances downloaded from this bank 
MyBankSession.prototype.logout = function(cb) {
    // Try to log out of the bank website, then call: 
    //  - cb(err)  on failure 
    //  - cb(null) on success 

Finally, drivers should export themselves as module.exports:

module.exports = MyBankSession;
