Create Square-Connected Applications in Appsmith

Appsmith is an open-source internal tool builder that allows teams to quickly and easily build a UI to help improve their business operations. When combined with CData Connect Cloud, you gain immediate access to Square data for business applications. This article outlines the process of connecting to Square using Connect Cloud and creating a basic application from Square data within Appsmith.

CData Connect Cloud offers a pure SQL Server, cloud-to-cloud interface for Square, enabling the creation of business applications directly from live Square data within Appsmith, all without the need for data replication to a native database. As you build applications, Appsmith generates SQL queries to gather data. With its inherent optimized data processing capabilities, CData Connect Cloud efficiently channels all supported SQL operations, including filters and JOINs, directly to Square. This leverages server-side processing to swiftly deliver the requested Square data.

Configure Square Connectivity for Appsmith

Connectivity to Square from Appsmith is made possible through CData Connect Cloud. To work with Square data from Appsmith, we start by creating and configuring a Square connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Square" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Square.

   Square uses the OAuth authentication standard. To authenticate using OAuth, register an app with Square to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

   Additionally, you must specify the LocationId. You can retrieve the Ids for your Locations by querying the Locations table. Alternatively, you can set the LocationId in the search criteria of your query.

   
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Square Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect Cloud through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect Cloud. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect Cloud app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, we are ready to connect to Square data from Appsmith.

Create an Appsmith Application from live Square Data

To establish a connection from Appsmith to the CData Connect Cloud Virtual SQL Server, follow these steps:

Connect to Square in Appsmith

1. Log in to your Appsmith instance and create a new application.
2. In the new application, open the Data page and select Bring your data.
3. On this page, you can search for Microsoft SQL Server and select it as your data source.
4. Enter a name for the new data source and then enter the following connection settings:
   • Host address: tds.cdata.com
   • Port: 14333
   • Database name: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, Square1).
   • Username: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, test@cdata.com.
   • Password: enter the PAT you previously generated.
   
5. Click Test configuration to confirm a successful connection, then click Save to save the datasource.

Create a new query

With a connection configured to a datasource, we can add a SQL query to actually retrieve data from the data source.

1. On the screen with the new data source, click New Query.
2. This opens the Query Editor to enter a SQL query to select data. To assist with specifying a SQL query, use the Explorer of CData Connect Cloud to preview the SQL queries and the data you want to retrieve.
3. After creating the SQL query, return to the Query Editor in Appsmith and enter the SQL query, then click Run.
4. Once the query successfully runs, all that remains is to set up the Page to display the data retrieved.

Display Square data

1. Open the UI tab and click New UI element.
2. Choose a new UI element to grab, then drag and place the element on the page.
3. Click Connect data on the new UI element, then select the query previously created.
4. With the data connected, it is then displayed in the UI element.

Deploy the application

With the Square data connected to the UI elements in the application, we can deploy the Application. To do this, click Deploy in the top-right corner of Appsmith, then the application is opened in a seperate window displaying the Square data.
