Step 3: Configure and call function #

Configuration options are available for utilizing dwolla.js in both our Sandbox and production environments. Configuration of an environment should take place after you have included the dwolla.js library.

javascript

// Sandbox
dwolla.configure("sandbox");

// Production
dwolla.configure("prod");

dwolla.fundingSources.create() #

Param	Type	Value
funding-sources-token	string	A funding sources token generated on your server.
params	object	An object containing params to create a funding source. Contains keys: `routingNumber`, `accountNumber`, `type`, and `name`. See example below. `routingNumber` represents a string value nine digit routing number. `accountNumber` represents a string value account number. `type` represents a string value of either `checking` or `savings`. `name` represents a string value identifying name of the user's bank.
callback	function	A callback function that handles the response from Dwolla.

Example

javascript

dwolla.fundingSources.create(
  "1zN400zyPUobbdmeNfhTGH2Jh5JkFREJa9YBI8SLXp0ERXNTMT",
  {
    routingNumber: document.getElementById("routingNumber").value,
    accountNumber: document.getElementById("accountNumber").value,
    type: document.getElementById("type").value,
    name: document.getElementById("name").value,
  },
  function (err, res) {
    console.log(
      "Error: " + JSON.stringify(err) + " -- Response: " + JSON.stringify(res)
    );
  }
);

Call JavaScript function to create a new funding source #

Assuming dwolla.js is already included and configured on your page, you will create the function that will call dwolla.fundingSources.create(). For this example, jQuery is used to call the function that creates a funding source when the user clicks the "Add Bank" button on your page. To test in the sandbox environment, use the dwolla.configure() helper function and pass in the value of sandbox.

In our example, dwolla.fundingSources.create() takes three arguments: a string value of the funding sources token, JavaScript object containing bank account information entered by the user, and a callback function that will handle any error or response.

javascript

$("form").on("submit", function () {
  dwolla.configure("sandbox");
  var token = "Z9BvpNuSrsI7Ke1mcGmTT0EpwW34GSmDaYP09frCpeWdq46JUg";
  var bankInfo = {
    routingNumber: document.getElementById("routingNumber").value,
    accountNumber: document.getElementById("accountNumber").value,
    type: document.getElementById("type").value,
    name: document.getElementById("name").value,
  };
  dwolla.fundingSources.create(token, bankInfo, callback);
  return false;
});

function callback(err, res) {
  var $div = $("<div />");
  var logValue = {
    error: err,
    response: res,
  };
  $div.text(JSON.stringify(logValue));
  console.log(logValue);
  $("#logs").append($div);
}
