Natively Connect to Talkdesk Data in PHP

Drop the CData ODBC Driver for Talkdesk into your LAMP or WAMP stack to build Talkdesk-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Talkdesk data, execute queries, and output the results.

Configure a DSN

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Talkdesk uses the OAuth 2.0 Client Credentials grant. There is no browser-based authorization step and no callback URL.

Set the following connection properties:

• AccountName: The name of your Talkdesk account.
• Region: The region where your Talkdesk instance is deployed. Supported values are US (default), EU, CA, AU, UK, and FedRamp.
• OAuthClientId: The Client Id assigned when you registered your custom OAuth application.
• OAuthClientSecret: The Client Secret assigned to your custom OAuth application.

Creating a Custom OAuth Application

1. Log in to your Talkdesk account and select OAuth Clients from the navigation menu.
2. Click Create OAuth Client and give the client a descriptive name.
3. Set Grant Type to Client Credentials.
4. Click Add scopes and select the scopes for the data you want to access.
5. Click Create and copy the Client Id and Client Secret.

When you connect, the driver automatically requests an access token from Talkdesk, caches it, and refreshes it when it expires. Make sure the scopes selected for the application match the views you plan to query, or the token request can fail.

Establish a Connection

Open the connection to Talkdesk by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

$conn = odbc_connect("CData ODBC Talkdesk Source","user","password");

Connections opened with odbc_connect are closed when the script ends. Connections opened with the odbc_pconnect method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources, and queries execute faster.

$conn = odbc_pconnect("CData ODBC Talkdesk Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the odbc_prepare function.

$query = odbc_prepare($conn, "SELECT * FROM Users WHERE Active = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC Talkdesk Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Users WHERE Active = ?");
$success = odbc_execute($query, array('true'));
  

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC Talkdesk Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Users WHERE Active = 'true'");
  

Process Results

Access a row in the result set as an array with the odbc_fetch_array function.

$conn = odbc_connect("CData ODBC Talkdesk data Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Users WHERE Active = 'true'");
while($row = odbc_fetch_array($query)){
 echo $row["Id"] . "\n";
}

Display the result set in an HTML table with the odbc_result_all function.

$conn = odbc_connect("CData ODBC Talkdesk data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Users WHERE Active = ?");
$success = odbc_execute($query, array('true'));
if($success)
  odbc_result_all($query);
