Plaid Component

Overview

The Plaid component connects to the Plaid service, allowing you to securely connect your applications to financial accounts. In Express View Express View is how your end-user views your application. Express View also lets you preview your applications to test your configuration and view the styling. This is also the view your end-users will see when interacting with your application. After configuring a module, click Preview in the Module Builder to interact with the module in Express View., the Plaid component displays as a button that your end-user End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. can click to securely log into their financial account. Once clicked, your application can access relevant and verified financial information. Because financial services have strict login requirements, the Plaid component can also verify an end-user's identity.

It's important to note that Plaid is just a data provider, and it doesn't perform financial transactions. To perform actual banking transactions, integration with Stripe is required.

The Account Linked button below displays a configured Plaid component in Express View Express View is how your end-user views your application. Express View also lets you preview your applications to test your configuration and view the styling. This is also the view your end-users will see when interacting with your application. After configuring a module, click Preview in the Module Builder to interact with the module in Express View.:

Your Plaid service can include any of the following Plaid products:

• Authentication

• Assets

• Identity

• Income

• Investments

• Liabilities

• Transactions

You'll find the Plaid component in the Data & Event Processing group to the left of the Module Builder.

What You'll Learn

After completing this article, you’ll know when to use a Plaid component, how to configure its settings, and understand the best practices.

About the Configuration Window

Once you drop a Plaid component onto the Module Builder canvas, the following settings windows display: 

General

Setting	Description
Property ID	A Property ID is the unique field ID used by Unqork to track and link components in your module. The Property ID is how the software identifies your component. Using Property IDs lets you link components, creating logic-based configurations and API APIs (application programming interfaces) are a set of protocols and definitions developers use to build and integrate application software. APIs act as the connective tissue between products and services. calls. Property IDs must use camel case A naming convention for computer programming. Use camelCase for Property IDs, for example: newUser, lastName, & rdoButton. (stylized as camelCase) without spaces or punctuation.
Notes	Select this tab to display the component's Notes area. You can use notes to keep your teammates informed. The Notes editor offers a semi-WYSIWYG (What You See is What You Get) content editor. Built to look like a word processor, this editor lets you create, edit, and format your notes. Notes save when saving the component.

Field Tags	Assign components one-word labels to help organize, identify, and group the components in your application. Consider an example from the API Specification Snippet: Field Tags are applied to Hidden components in the panelRequest and panelResponse Panel components. The Field Tags identify the data type of parameters included in the API APIs (application programming interfaces) are a set of protocols and definitions developers use to build and integrate application software. APIs act as the connective tissue between products and services. request and response. The API Docs Dashboard tool populates with information about each parameter’s data type, identified by the Field Tag. Field Tags act as a type of Property ID A Property ID is the unique field ID used by Unqork to track and link components in your module. group and let you group components for configuration purposes. Field Tags let you target two or more components using a simple logic component. For example, add the Field Tag tagForDecision to multiple components in your module. Open the Inputs table of a Decisions component and reference the tagForDecision Field Tag as the input of the Decisions component. The output of the Decisions component then affects all components with the tagForDecision Field Tag. Save your Field Tags by pressing Enter (Return) or adding a comma after each entry.
Shortcuts	Select this tab to open the list of supported keyboard shortcuts you can use in the component settings modal. Keyboard shortcuts include: Cmd + S (Mac) / Ctrl + S (PC): Save and close the component settings modal. Cmd + G (Mac) / Ctrl + G (PC): Opens a search window to find specific fields and settings in the component settings modal. Tab: Tab to the next field or setting in the component settings modal. This keyboard shortcut tabs left to right and top to bottom. Shift + Tab: Tab to the previous field or setting in the component settings modal.

Adding the Plaid Component

In this example, you'll build a module that uses a Plaid component to link an end-user's bank account. Once linked, a simple dashboard displays some basic account information.

If you configure a Plaid component in a live application, ensure all Plug-In components execute server-side. For more information on server-side execution, view our Server-Side Module Execution article.

• 1 Plaid component

• 1 Field Group component

• 2 Hidden components

• 1 Plug-In component

• 1 Data Table component

• 1 ViewGrid component

• 2 Data Workflow components

To set up the first Data Workflow, you need:

• 1 Input operator

• 1 Get operator

• 2 Output operator

To set up the second Data Workflow, you need:

• 2 Input operators

• 2 Get operators

• 1 Merge operator

• 1 Map Keys operator

Setting up the Plaid Service

Before configuring the Plaid component, you need to set up the Plaid service in your environment. If a Plaid service is already set up in your environment, you can skip this section.

Setting up a Plaid service creates a back-end endpoint for your Plaid component and adds a layer of security. The API APIs (application programming interfaces) are a set of protocols and definitions developers use to build and integrate application software. APIs act as the connective tissue between products and services. call occurs in an Unqork server and not your browser.

To connect to Plaid, you'll need a developer account and a set of Plaid API keys. To learn more, see Plaid's Quickstart article: https://plaid.com/docs/quickstart/

Before setting up Plaid, ensure you have a Plaid administrator and that you've set up an API account with Plaid. As a best practice, every client should have one Plaid account and each module should have a minimum of one Plaid component. To set up Plaid in your environment, do the following:

1.
