MXquickconnect Demo App

Set up our demo app and use the Connect Widget yourself

One way to get started with our Connect Widget is by using our MXquickconnect demo app. The app, coupled with sample code, demonstrates adding new users and members (connecting a user to their financial account) and making additional requests for different use cases.

warning

The demo app isn't intended as a starting point for implementing the Connect Widget. It's a way of demonstrating functionality available in the Connect Widget.

To use the MXquickconnect demo app, you'll need to:

  1. Sign up for the Platform API and get your api_key and client_id from the Client Dashboard to set up the backend.
  2. Clone the app from our GitHub repository.
  3. Setup the backend.
  4. Setup the frontend.
  5. Use the app and explore other features.

Backend Setup​

The app requires that you set up the frontend and backend for a successful launch.

You can run the backend with either Ruby, Node.js, Python3, or AspNet.

  1. Open your terminal and clone the app from GitHub if you haven’t already.
  2. Navigate to the mx-quickconnect folder using cd mx-quickconnect.
  3. Set up an environment using the following commands in your terminal:
    • cp .env.example .env
    • vi .env
  4. Insert your api_key and client_id from the Client Dashboard. (Note: To enter, type i to enter insert mode, then move the cursor and type in your values. Finally, type :wq ENTER on your keyboard to save and exit the file.)
  5. Run the backend using one of the following sets of commands, depending on your language.

_10
cd mx-platform-aspnet-core
_10
dotnet add package MX.Platform.CSharp
_10
dotnet run

Backend Setup Complete!

Your backend should now be up and running. Do not close the terminal.

Frontend Setup​

Once your backend is running, set up your frontend. All frontend implementations run Node.js. You must have npm version 7 or higher installed.

Your localhost runs automatically from your default browser. If your browser does not automatically appear, enter localhost:3000 into your preferred browser.

  1. Open a new terminal. Make sure to keep the backend terminal open and running.
  2. Navigate back to the folder you cloned your project in.
  3. Run the following commands in your terminal:

_10
cd frontend
_10
npm install
_10
npm start

note

You may experience a pop-up asking for permission to your browser if you haven't already granted your terminal permission.

Using the Demo App​

After you set up the backend and frontend, your browser displays the app homepage. From here, you'll be guided through creating a user and a member. Creating a user and member connects the end user's financial account to the MX platform. After you've created your first user, you can return and launch the app with a previously created user, or you can create a new user.

The app limits you to 5 users.

The following steps explain how to use the widget with OAuth and example data.

  1. Select one of the Launch buttons to get started.
    • If it's your first time using the app, select Launch with new user.
    • If you've visited the app before, you can either select Launch with new user to create a new user or Launch with previous user to continue with a user that has already been created.
    • When you select one of the Launch buttons, an embedded widget appears. The page also displays example information you'll need make a successful connection including a bank, username, and passwords.
  2. Select Continue. A list of financial institutions appears.
  3. Select MX Bank (OAuth). The Sign In page appears.
  4. Select Sign in. An Authorization Required page appears. This is an example of how OAuth is implemented to provide an end user with additional security. 
  5. Select Authorize. After the user is verified, the account selection page appears.
  6. Select an account. The app shows two options (savings or checking) for this demo. You can select either one.
  7. Select Continue. This verifies the information provided. When successful, the page displays the userGuid and memberGuid.

The userGuid and memberGuid are results of a successful verification. These two GUIDs can be used to complete additional requests to the MX Platform API. In the rest of this guide, these two GUIDs are used to automatically make requests to additional endpoints.

More Features​

After you've used the app to create users and members, use some of the other features provided by the demo app. Our app provides you with a few of our most common uses cases including:

  • Instant Account Verification (account and routing numbers)
  • Account Owner Identification (name, address, etc.)
  • Balance Checks
  • Listing Transactions

For each request, select the Run button next to the request you'd like to make. The app displays the following information for each request:

  • The method and endpoint required to request the information. 
  • A brief description of the endpoint. 
  • The information returned in plain text format as a table. 
  • The request payload in JSON.
tip

Toggle between plain text and JSON by clicking the icons next to the description.
