• Prerequisites
• Connecting to CData Connect Cloud

This page outlines the steps to connect Apps Script to CData Connect Cloud via the Query API.

Prerequisites

Before you connect, you must first do the following:

• Connect a data source to your CData Connect Cloud account. See Connections for more information.
• Generate a Personal Access Token (PAT) on the Settings page. Copy this down, as it acts as your password during authentication.

Connecting to CData Connect Cloud

In order to connect from Apps Script to CData Connect Cloud via the Query API, you need the following information:

• URL—https://cloud.cdata.com/api/query

• 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 generated on the Settings page.

1. Log in to Apps Script (https://script.google.com).

2. Create a new Apps Script project.

3. Copy and paste the script below into the Apps Script project. This script connects your data source to the Query API and outputs the results to the Apps Script console.

   Change the following in the script:

   • Update username with your CData Connect Cloud username.

   • Update password with the PAT you generated in the prerequisites.

   • Update query with your database query.

   function postQueryToAPI() {
    // Define the API endpoint and authentication
    const apiUrl = 'https://cloud.cdata.com/api/query';
    const username = 'CONNECT_CLOUD_USERNAME'; // Replace with your API username
    const password = 'CONNECT_CLOUD_PAT' // Replace with your API password or PAT
    
    // Define the query payload
    const queryPayload = {
        query: "SELECT * FROM [Snowflake1].[PUBLIC].[Account]"
    };
    
    // Options for the POST request
    const options = {
        method: 'POST',
        headers: {
            'Authorization': 'Basic ' + Utilities.base64Encode(username + ':' + password),
            'Content-Type': 'application/json'
        },
        payload: JSON.stringify(queryPayload) // Convert payload to JSON
    };
    
    try {
        // Send the POST request to the API
        const response = UrlFetchApp.fetch(apiUrl, options);
    
        // Parse the JSON response
        const jsonResponse = JSON.parse(response.getContentText());
    
        const schema = jsonResponse.results[0].schema;
        const rows = jsonResponse.results[0].rows;
    
       // Create a mapped result
        const parsedResults = rows.map(row => {
        let rowData = {};
        schema.forEach((column, index) => {
            rowData[column.columnLabel] = row[index];
        });
        return rowData;
        });
    
        // Log the response to check the result
        Logger.log('Parsed Results: ' + JSON.stringify(parsedResults, null, 2));
    } catch (e) {
        // Handle errors and log the message
        Logger.log('Error: ' + e.message);
    }
   }
   

4. Name and save your Apps Script project.

   

5. Run the script.

   Note: The first time you run the script, you need to authorize it to make external connections. Click Review Permissions and follow the prompts to grant the necessary permissions.

6. The Execution log displays the query output as a JSON object:
