Step 1: Setup and configuration #

We’ll begin by setting up and configuring both the Dwolla Components library and installing a server-side SDK. This guide assumes that you have the basic structure of a web application set up and running, which includes a backend language (e.g. Node.js, Python, etc.) and a web front end (HTML, CSS, Javascript).

To get up and running quickly, take a look at our drop-ins examples repo which is a basic Node.js app that uses Express.

Include dwolla-web.js #

Begin the client-side implementation by including dwolla-web.js in the ‘head’ of your HTML page. The Dwolla Components library containing all of the drop-in UI components are available directly from Dwolla’s content delivery network (CDN). As we continue to evolve the components library, it will soon be available to be installed via NPM.

html
<head>
  <script
    type="text/javascript"
    src="//cdn.dwolla.com/v2/dwolla-web.js"
  ></script>
</head>

Install and configure server-side SDK #

Dwolla has a collection of SDKs available in a variety of server-side programming languages. You’ll want to be sure to install an SDK or utilize a third party HTTP client library before completing Step 2.

Install

JavaScript
npm install dwolla-v2

Configure

JavaScript
const dwolla = require("dwolla-v2");

// Navigate to https://dashboard.dwolla.com/applications (production) or https://dashboard-sandbox.dwolla.com/applications (Sandbox) for your application key and secret.
const appKey = "...";
const appSecret = "...";
const client = new dwolla.Client({
  key: appKey,
  secret: appSecret,
  environment: "sandbox", // optional - defaults to production
});

Now that we’ve completed our initial setup, we’ll move on to the next step of generating a “client-token” which will be used when configuring the drop-in components library.
