Create Apollo-Connected Enterprise Applications in OutSystems

OutSystems is a low-code platform which provides the tools for companies to developer, deploy, and manage omnichannel enterprise applications. When paired with CData Connect AI, you get instant, cloud-to-cloud access to Apollo data for business applications. This article shows how to create a virtual database for Apollo in Connect AI and build a simple app from Apollo data in OutSystems.

The CData Connect AI provides a pure cloud-to-cloud interface for Apollo, allowing you to build reports from live Apollo data in OutSystems — without replicating the data to a natively supported database. As you create applications to work with data, OutSystems generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc.) directly to Apollo, leveraging server-side processing to quickly return the requested Apollo data.

Configure Apollo Connectivity for OutSystems

Connectivity to Apollo from OutSystems is made possible through CData Connect AI. To work with Apollo data from OutSystems, we start by creating and configuring a Apollo connection.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Apollo" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Apollo.

   To connect to Apollo, register an OAuth application in Apollo at Settings > Integrations > API > OAuth Registration. Set the Redirect URI to https://oauth.cdata.com/oauth/. Copy the Client Id and Client Secret (the secret is shown only once). Then set the following:

   • OAuth Client Id: Set this to the Client Id from your Apollo OAuth application.
   • OAuth Client Secret: Set this to the Client Secret from your Apollo OAuth application.

   Click Sign In to complete OAuth authentication.

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

Add a Personal Access Token

When connecting to Connect AI 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 AI. 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 AI 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, you are ready to connect to Apollo data from OutSystems.

Connect to Apollo from OutSystems

The steps below outline connecting to CData Connect AI from OutSystems to create a new Apollo database connection.

1. Open OutSystems Service Studio
2. Click the gear icon to open Environment Management in the Service Center
3. Click Administration and select "Database Connections"
4. Click "New Database Connection"
5. Configure the database connection:
   • Name: name the connection (e.g. CData Connect AI Apollo)
   • DBMS: SQL Server / Azure SQL
   • Username: a Connect AI user (e.g. [email protected])
   • Password: the PAT for the Connect AI user
   • Server: tds.cdata.com,14333
   • Schema: the name of your Apollo connection (e.g. API1)
   
6. Click "Test Connection"
7. Click "Create"

Map Apollo Tables or Views to Entities in an Extension Module

Once you create the database connection for Apollo, you can create an extension that maps the tables or views to OutSystems entities. If you have not already done so, create an Application in Service Studio.

1. Open the Service Studio and open the existing Application
2. Click "Add Module," set the "Module Name" (e.g. api_db_extension), set "Module Type" to "Extension," and click "Create Module"
3. In Integration Studio, connect to your environment
4. Right-click "Entities" in the extension tree and select "Connect to External Table or View..."
5. Follow the steps in the wizard, selecting the tables and views you wish to work with
6. In the Integration Studio, click "1-Click Publish"
7. In the "1-Click Publish" wizard, click "Configure" when the process completes
   • In the Service Center, associate the logical database name of the extension to the database connection that the extension will use and click "Apply"
8. In your application, click "Manage Dependencies..."
9. Add a dependency to the Extension and select the Entities that you will use in your application

At this point, you can access and work with Apollo data just like you would with the standard OutSystems entities.
