Connect to WooCommerce Data in Google Apps Script via Connect AI

Google Apps Script empowers users to build custom functionality within their Google documents, including Google Sheets and Google Docs. Apps Script natively supports SQL Server connectivity via JDBC, providing a powerful extensibility tool for connecting Google cloud applications to external data. Paired with the SQL connectivity offered by CData Connect AI, users can easily access live WooCommerce data directly from within their Google documents.

This article shows how to connect to WooCommerce in Connect AI and provides sample scripting for processing WooCommerce data in a Google Spreadsheet.

Our script only reads data from a specified table, but you can easily extend the script to incorporate update functionality.

Configure WooCommerce Connectivity for Google Apps Scripts

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

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
👁 Adding a Connection

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

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

   WooCommerce supports the following authentication methods: one-legged OAuth1.0 Authentication and standard OAuth2.0 Authentication.

   Connecting using one-legged OAuth 1.0 Authentication

   Specify the following properties (NOTE: the below credentials are generated from WooCommerce settings page and should not be confused with the credentials generated by using WordPress OAuth2.0 plugin):

   • ConsumerKey
   • ConsumerSecret

   Connecting using WordPress OAuth 2.0 Authentication

   After having configured the

   • OAuthClientId
   • OAuthClientSecret
   • CallbackURL
   • InitiateOAuth - Set this to either GETANDREFRESH or REFRESH

   In either case, set the Url property to the URL of the WooCommerce instance.

   👁 Configuring a connection (Salesforce is shown)
   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add WooCommerce 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.

With the connection configured and a PAT generated, you are ready to connect to WooCommerce data from Google Apps Script.

Connect to WooCommerce Data from Apps Script

At this point, you should have configured a connection WooCommerce in Connect AI. All that is left new is to use Google Apps Script to access Connect AI and work with your WooCommerce data in Google Sheets.

In this section, you will create a script (with a menu option to call the script) to populate a spreadsheet with WooCommerce data. We have created a sample script and explained the different parts. You can view the raw script at the and of the article.

1. Create an Empty Script

To create a script for your Google Sheet, click Tools Script editor from the Google Sheets menu:

👁 Open script editor

2. Declare Class Variables

Create a handful of class variables to be available for any functions created in the script.

//replace the variables in this block with real values as needed
var address = 'tds.cdata.com:14333';
var user = 'CONNECT_USER'; // [email protected]
var userPwd = 'CONNECT_USER_PAT';
var db = 'WooCommerce1';

var dbUrl = 'jdbc:sqlserver://' + address + ';databaseName=' + db;

3. Add a Menu Option

This function adds a menu option to your Google Sheet, allowing you to use the UI to call your function.

function onOpen() {
 var spreadsheet = SpreadsheetApp.getActive();
 var menuItems = [
 {name: 'Write data to a sheet', functionName: 'connectToWooCommerceData'}
 ];
 spreadsheet.addMenu('WooCommerce Data', menuItems);
} 

👁 The newly added Menu option.

4. Write a Helper Function

This function is used to find the first empty row in a spreadsheet.

/*
 * Finds the first empty row in a spreadsheet by scanning an array of columns
 * @return The row number of the first empty row.
 */
function getFirstEmptyRowByColumnArray(spreadSheet, column) {
 var column = spreadSheet.getRange(column + ":" + column);
 var values = column.getValues(); // get all data in one call
 var ct = 0;
 while ( values[ct] && values[ct][0] != "" ) {
 ct++;
 }
 return (ct+1);
}

5. Write a Function to Write WooCommerce Data to a Spreadsheet

The function below writes the WooCommerce data, using the Google Apps Script JDBC functionality to connect to Connect AI, SELECT data, and populate a spreadsheet. When the script is run, two input boxes will appear:

The first one asks the user to input the name of a sheet to hold the data (if the spreadsheet does not exist, the function creates it).

👁 Input box for sheet selection.

The second asks the user to input the name of a WooCommerce table to read. If an invalid table is chosen, an error message appears and the function is exited.

👁 Input box for table selection.

Note, while the function is designed for use as a menu option, you can extend it for use as a spreadsheet formula.

/*
 * Reads data from a specified WooCommerce 'table' and writes it to the specified sheet.
 * (If the specified sheet does not exist, it is created.)
 */
function connectToWooCommerceData() {
 var thisWorkbook = SpreadsheetApp.getActive();

 //select a sheet and create it if it does not exist
 var selectedSheet = Browser.inputBox('Which sheet would you like the data to post to?',Browser.Buttons.OK_CANCEL);
 if (selectedSheet == 'cancel')
 return;

 if (thisWorkbook.getSheetByName(selectedSheet) == null)
 thisWorkbook.insertSheet(selectedSheet);
 var resultSheet = thisWorkbook.getSheetByName(selectedSheet);
 var rowNum = 2;

 //select a WooCommerce 'table'
 var table = Browser.inputBox('Which table would you like to pull data from?',Browser.Buttons.OK_CANCEL);
 if (table == 'cancel')
 return;

 var name = Jdbc.getConnection(dbUrl, {
 user: user, 
 password: userPwd
	}	
 );

 //confirm that var table is a valid table/view
 var dbMetaData = name.getMetaData();
 var tableSet = dbMetaData.getTables(null, null, table, null);
 var validTable = false;
 while (tableSet.next()) {
 var tempTable = tableSet.getString(3);
 if (table.toUpperCase() == tempTable.toUpperCase()){
 table = tempTable;
 validTable = true;
 break;
 }
 } 
 tableSet.close();
 if (!validTable) {
 Browser.msgBox("Invalid table name: " + table, Browser.Buttons.OK);
 return;
 }

 var stmt = name.createStatement();

 var results = stmt.executeQuery('SELECT * FROM ' + table);
 var rsmd = results.getMetaData();
 var numCols = rsmd.getColumnCount();

 //if the sheet is empty, populate the first row with the headers
 var firstEmptyRow = getFirstEmptyRowByColumnArray(resultSheet, "A");
 if (firstEmptyRow == 1) {
 //collect column names
 var headers = new Array(new Array(numCols));
 for (var col = 0; col < numCols; col++){
 headers[0][col] = rsmd.getColumnName(col+1);
 }
 resultSheet.getRange(1, 1, headers.length, headers[0].length).setValues(headers);
 } else {
 rowNum = firstEmptyRow;
 }

 //write rows of WooCommerce data to the sheet
 var values = new Array(new Array(numCols));
 while (results.next()) {
 for (var col = 0; col < numCols; col++) {
 values[0][col] = results.getString(col + 1);
 }
 resultSheet.getRange(rowNum, 1, 1, numCols).setValues(values);
 rowNum++;
 }

 results.close();
 stmt.close();
}
 

When the function is completed, you have a spreadsheet populated with your WooCommerce data, and you can now leverage all of the calculating, graphing, and charting functionality of Google Sheets anywhere you have access to the Internet.
