Build Oracle Eloqua-Connected Web Apps with Axios and CData Connect AI

Axios is a JavaScript library that allows developers to make HTTP requests to servers from a web browser or Node.js. When paired with CData Connect AI, you get access to live Oracle Eloqua data for your web apps. This article shows how to connect to Oracle Eloqua and build web apps in Axios with access to live Oracle Eloqua data.

Connect to Oracle Eloqua from Axios

To work with Oracle Eloqua in Axios, we need to connect to Oracle Eloqua from Connect AI, provide user access to the connection, and create a Workspace for the Oracle Eloqua data.

Connect to Oracle Eloqua from Connect AI

CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.

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

2. Select "Oracle Eloqua" from the Add Connection panel
👁 Selecting a data source

3. Enter the necessary authentication properties to connect to Oracle Eloqua.

   There are two authentication methods available for connecting to Oracle Eloqua: Login and OAuth. The Login method requires you to have the Company, User, and Password of the user.

   If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication. OAuth is better suited for allowing other users to access their own data. Using login credentials is better suited for accessing your own data.

4. Click Save & Test
5. Navigate to the Permissions tab in the Add Oracle Eloqua Connection page and update the User-based permissions. 👁 Updating 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. 👁 Creating a new PAT
   
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Configure Oracle Eloqua Endpoints for Axios

After connecting to Oracle Eloqua, create a workspace for your desired table(s).

1. Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace). 👁 The Workspaces page.
   👁 Adding a new Workspace.
   
2. Click Add to add new assets to the Workspace.
3. Select the Oracle Eloqua connection (e.g. OracleEloqua1) and click Next. 👁 Selecting an Asset (Salesforce is shown).
   
4. Select the table(s) you wish to work with and click Confirm. 👁 Selecting Tables (Salesforce is shown).
   
5. Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}

With the connection, PAT, and Workspace configured, you are ready to connect to Oracle Eloqua data from Axios.

Connect to Oracle Eloqua Data in Axios Workflows

To establish a connection from Axios to CData Connect AI using the OData protocol, follow these steps.

1. Create a project directory for your web app. For example: ~/connect_cloud/
2. Open a terminal, navigate the the project directory and initialize a node project using the command:

   npm init -y

3. Install the Axios dependency in the project using the following command:

   npm install axios

4. In your project directory, create a file called server.js that contains the following code. Provide your CData Connect AI username (e.g. [email protected]) and PAT (the PAT you created in the prerequisites). You must also provide a query for your data, such as SELECT * FROM OracleEloqua1.SCHEMA.Campaign.

   server.js code

    const axios = require('axios')
   
    const user = '[email protected]'
    const pat = '***********************************';
   
    //Your API endpoint
    const url = 'https://cloud.cdata.com/api/odata/{workspace_name}';
   
    //Your data to be sent in the POST request
    const data = {
    "query":"SELECT * FROM {workspace_name}.SCHEMA.Campaign"
    };
   
    axios.post(url, data, {
    auth: {
    username: user,
    password: pat
    }
    })
    .then(response => {
    const rows = response.data.results[0].rows;
    const schema = response.data.results[0].schema;
   
    //Create an array of column names
    const columnNames = schema.map(col => col.columnName);
   
    //Loop through each row and log the column name with its value
    rows.forEach(row => {
    const rowObject = {};
    row.forEach((value, index) => {
    const columnName = columnNames[index];
    rowObject[columnName] = value;
    });
    console.log(rowObject);
    })
    })
    .catch(error => {
    console.error('Error:', error);
    });
    

5. In the terminal, execute the following command to run the server:

   node server.js

   The query results will appear:

    { ID: 1, VALUE: -2 }
    { ID: 2, VALUE: 1 }
    { ID: 11, VALUE: null }
    { ID: 3, VALUE: 2 }
    { ID: 4, VALUE: 5 }
    ...
