Build Certinia-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 Certinia data for your web apps. This article shows how to connect to Certinia and build web apps in Axios with access to live Certinia data.
Connect to Certinia from Axios
To work with Certinia in Axios, we need to connect to Certinia from Connect AI, provide user access to the connection, and create a Workspace for the Certinia data.
Connect to Certinia from Connect AI
CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.
- Log into Connect AI, click Sources, and then click Add Connection
- Select "Certinia" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Certinia.
There are several authentication methods available for connecting to Certinia: login credentials, SSO, and OAuth.
Authenticating with a Login and Token
Set the User and Password to your login credentials. Additionally, set the SecurityToken. By default, the SecurityToken is required, but you can make it optional by allowing a range of trusted IP addresses.
To disable the security token:
- Log in to Certinia and enter "Network Access" in the Quick Find box in the setup section.
- Add your IP address to the list of trusted IP addresses.
To obtain the security token:
- Open the personal information page on certinia.com.
- Click the link to reset your security token. The token will be emailed to you.
- Specify the security token in the SecurityToken connection property or append it to the Password.
Authenticating with OAuth
If you do not have access to the user name and password or do not want to require them, use the OAuth user consent flow. See the OAuth section in the Help for an authentication guide.
Connecting to Certinia Sandbox Accounts
Set UseSandbox to true (false by default) to use a Certinia sandbox account. Ensure that you specify a sandbox user name in User.
- Click Save & Test
-
Navigate to the Permissions tab in the Add Certinia 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.
- Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
Configure Certinia Endpoints for Axios
After connecting to Certinia, create a workspace for your desired table(s).
-
Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace).
- Click Add to add new assets to the Workspace.
-
Select the Certinia connection (e.g. Certinia1) and click Next.
-
Select the table(s) you wish to work with and click Confirm.
- 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 Certinia data from Axios.
Connect to Certinia Data in Axios Workflows
To establish a connection from Axios to CData Connect AI using the OData protocol, follow these steps.
- Create a project directory for your web app. For example: ~/connect_cloud/
- Open a terminal, navigate the the project directory and initialize a node project using the command:
npm init -y
- Install the Axios dependency in the project using the following command:
npm install axios
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 Certinia1.SCHEMA.Account.
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.Account" }; 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); });- 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 } ...
