Use CData Connect Server to access Clio data in Google Apps Script.
Google Apps Script gives you the ability to create custom functionality within your Google documents, including Google Sheets, Google Docs, and more. With CData Connect Server, you get a SQL Server interface for any of the 200+ sources supported by CData, including Clio. The SQL Server protocol is natively supported through the JDBC service in Google Apps Script, so by utilizing Connect Server, you gain access to live Clio data within your Google documents.
This article shows how to create a virtual database for Clio in Connect Server and provides sample scripting for processing Clio data in a Google Spreadsheet.
CData Connect Server provides a pure SQL Server interface for Clio, allowing you to easily build reports from live Clio data in Apps Script — without replicating the data to a natively supported database. As you build visualizations, Apps Script generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to Clio, leveraging server-side processing to quickly return the requested Clio data.
Create a Virtual SQL Server Database for Clio Data
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Login to Connect Server and click Connections.
- Select "Clio" from Available Data Sources.
-
Enter the necessary authentication properties to connect to Clio.
Start by setting the Profile connection property to the location of the Clio Profile on disk (e.g. C:\profiles\Clio.apip). Next, set the ProfileSettings connection property to the connection string for Clio (see below).
Clio API Profile Settings
Clio uses OAuth-based authentication.
First, register an OAuth application with Clio. You can do so by logging to your Developer Account and clicking the Add button. Enter details and select the scope of your application here - these details will be shown to Clio users when they're asked to authorize your application. Your Oauth application will be assigned a client id (key) and a client secret (secret). Additionally you will need to set the Region in ProfileSettings connection property.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to OAuth.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
- OAuthClientId: Set this to the client_id that is specified in you app settings.
- OAuthClientSecret: Set this to the client_secret that is specified in you app settings.
- CallbackURL: Set this to the Redirect URI that is specified in your app settings.
- Region: Set this in ProfileSettings to your Clio geographic region. Defaults to app.clio.com.
- Click Save Changes
- Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.
With the virtual database created, you are ready to connect to Clio data from Apps Script.
Connect to Clio Data with Apps Script
At this point, you should have configured a virtual database for Clio in Connect Server. All that is left now is to use Google Apps Script to access Connect Server and work with your Clio 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 Clio data. We have created a sample script and explained the different parts. You can view the raw script at the end 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:
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 = 'CONNECT_SERVER_URL:port'; var user = 'CONNECT_USER'; var userPwd = 'CONNECT_PASSWORD'; var db = 'cliodb'; var serverSslCert = '-----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----'; var clientSslCert = '-----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----'; var clientSslKey = '-----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----'; var dbUrl = 'jdbc:sqlserver://' + address + '/' + db + '?useSSL=true';
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: 'connectToAPIData'} ]; spreadsheet.addMenu('Clio Data', menuItems); }
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 Clio Data to a Spreadsheet
The function below writes the Clio data, using the Google Apps Script JDBC functionality to connect to Connect Server, 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).
The second asks the user to input the name of a Clio table to read. If an invalid table is chosen, an error message appears and the function is exited.
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 Clio 'table' and writes it to the specified sheet. * (If the specified sheet does not exist, it is created.) */ function connectToAPIData() { 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 Clio 'table' var table = Browser.inputBox('Which table would you like to pull data from?',Browser.Buttons.OK_CANCEL); if (table == 'cancel') return; var conn = Jdbc.getConnection(dbUrl, { user: user, password: userPwd, _serverSslCertificate: serverSslCert, _clientSslCertificate: clientSslCert, _clientSslKey: clientSslKey ); //confirm that var table is a valid table/view var dbMetaData = conn.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 = conn.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 Clio 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 Clio data, and you can now leverage all of the calculating, graphing, and charting functionality of Google Sheets anywhere you have access to the Internet.
