ODBC Driver for Workday

Build 24.0.9060

Windows DSN Configuration

Using the Microsoft ODBC Data Source Administrator

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.

Complete the following steps to edit the DSN configuration:

  1. Select Start > Search, and enter ODBC Data Sources in the Search box.
  2. Choose the version of the ODBC Administrator that corresponds to the bitness of your application (32-bit or 64-bit).
  3. Click the System DSN tab.
  4. Select the system data source and click Configure.
  5. Edit the information on the Connection tab and click OK.

Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.

Ensuring Registry Access

The driver stores connection information in the Windows registry. To ensure that the driver can write to the registry, perform either of the following actions:

  1. Run the calling application as an administrator.
  2. Connect via a User DSN instead of a System DSN.

Connecting to Workday

This section describes how to set the connection parameters for the four Workday APIs, and how to obtain the Tenant and BaseURL. Each service (WQL, Reports, REST, and SOAP) has its own ConnectionType, and only one connection type can be used per connection.

After you set the parameters for the desired API and have created a custom OAuth and/or Azure AD API client, you are ready to connect.

Connection Prerequisites

API Prerequisites Connection Parameters
WQL Enable WQL service
(See below) 		ConnectionType: WQL
Reports as a Service Set up catalog report
(see Fine-Tuning Data Access) 		ConnectionType: Reports
REST Automatically enabled ConnectionType: REST
SOAP Automatically enabled See Workday SOAP API, below

Obtaining the BaseURL and Tenant

To obtain the BaseURL and Tenant properties, log into Workday and search for View API Clients. On this screen, Workday displays the Workday REST API Endpoint, a URL that includes both the BaseURL and Tenant.

The format of the REST API Endpoint is: https://domain.com/subdirectories/mycompany, where:

  • https://domain.com/subdirectories/ is the BaseURL.
  • mycompany (the portion of the url after the very last slash) is the Tenant.

For example, in the REST API endpoint https://wd3-impl-services1.workday.com/ccx/api/v1/mycompany, the BaseURL is https://wd3-impl-services1.workday.com and the Tenant is mycompany.

Enabling WQL Service

To connect through the Workday WQL API, you must first enable the WQL Service:

  1. Open Workday.
  2. In the search bar, search for View Domain.
  3. At the prompt, enter Workday Query Language.
  4. Check the Allowed Security Group Types to see if one of them includes the user you are connecting with.

Authenticating to Workday

Most Workday connections require the creation of an OAuth-based custom API Client application to authenticate. This includes enterprise installations where users connect via their Azure AD credentials. If you want to connect via SOAP, you can use Basic authentication, which doesn't require a custom OAuth application.

This section describes both methods of authentication.

OAuth

This section describes how to authenticate in an environment without SSO, using the OAuth standard. Before you can authenticate in this environment, you must first create a custom OAuth application, as described in Creating a Custom API Client Application.

Note: Because they facilitate authentication to Workday APIs, this document frequently refers to custom OAuth applications as custom API Clients.

Desktop Applications

To authenticate with the credentials for a custom OAuth application, you must get and refresh the OAuth access token. After you do that, you are ready to connect.

Get and refresh the OAuth access token:

  • InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
  • OAuthClientId: The client Id assigned when you registered your application.
  • OAuthClientSecret: The client secret that was assigned when you registered your application.
  • CallbackURL: The redirect URI that was defined when you registered your application.

When you connect, the driver opens Workday's OAuth endpoint in your default browser. Log in and grant permissions to the application.

When the access token expires, the driver refreshes it automatically.

Headless Machines

If you need to log in to a resource that resides on a headless machine, you must authenticate on another device that has an internet browser. You can do this in either of the following ways:

  • Option 1: Obtain the OAuthVerifier value.
  • Option 2: Install the driver on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow.

After you execute either Option 1 or Option 2, configure the driver to automatically refresh the access token on the headless machine.

Option 1: Obtaining and Exchanging a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL. Do the following:

  1. Authenticate from the machine with an internet browser, and obtain the OAuthVerifier connection property.

    Set the following properties:

    • InitiateOAuth: OFF.
    • OAuthClientId: The client Id assigned when you registered your application.
    • OAuthClientSecret: The client secret assigned when you registered your application.

  2. Call the GetOAuthAuthorizationURL stored procedure. The stored procedure returns the CallbackURL established when the custom OAuth application was registered. (See Creating a Custom API Client Application.)

    Copy this URL and paste it into a new browser tab.

  3. Log in and grant permissions to the driver. The OAuth application redirects you the redirect URI, with a parameter called code appended. Note the value of this parameter; you will need it later, to configure the OAuthVerifier connection property.

  4. Exchange the OAuth verifier code for OAuth refresh and access tokens. On the headless machine, set the following connection properties to obtain the OAuth authentication values:

    • InitiateOAuth: REFRESH.
    • OAuthVerifier: The noted verifier code (the value of the code parameter in the redirect URI).
    • OAuthSettingsLocation: Persist the encrypted OAuth authentication values to the specified file.
    • OAuthClientId: The client Id in your custom OAuth application settings.
    • OAuthClientSecret: The client secret in the custom OAuth application settings.

  5. Test the connection to generate the OAuth settings file.

  6. After you re-set the following properties, you are ready to connect:

    • InitiateOAuth: REFRESH.
    • OAuthSettingsLocation: The file containing the encrypted OAuth authentication values. To enable the automatic refreshing of the access token, be sure that this file gives read and write permissions to the driver.
    • OAuthClientId: The client Id assigned when you registered your application.
    • OAuthClientSecret: The client secret assigned when you registered your application.

Option 2: Transferring OAuth Settings

Prior to connecting on a headless machine, you must install and create a connection with the driver on a device that supports an internet browser. Set the connection properties as described above in "Desktop Applications".

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the path specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.

Test the connection to generate the OAuth settings file, then copy the OAuth settings file to your headless machine.

To connect to data via the headless machine, set the following connection properties:

  • InitiateOAuth: REFRESH
  • OAuthSettingsLocation: The path to the OAuth settings file you copied from the machine with the browser. To enable automatic refreshing of the access token, ensure that this file gives read and write permissions to the driver.
  • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
  • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

Authenticating as a Normal User

To authenticate as a normal user in Workday, you must first create an API Client, as described in Creating a Custom API Client Application.

After you have an API client configured, set the following properties to connect using Workday credentials:

Standard OAuth User

  • ConnectionType and related properties.
  • AuthScheme: OAuth.
  • OAuthClientId: The Client ID obtained from the View API Client page.
  • OAuthClientSecret: The Client Secret obtained from the View API Client page. If you are using a public client, leave this blank.
  • Tenant: The tenant for the account.
  • BaseURL: The base URL for the REST API Endpoint in the View API Clients page.

AzureAD User

  • ConnectionType and related properties.
  • AuthScheme: AzureAD.
  • OAuthClientId: The Client ID obtained from the View API Client page.
  • Tenant: The tenant for the account.
  • BaseURL: The base URL for the REST API Endpoint in the View API Clients page.
  • SSOProperties: The Azure-specific properties used for SSO, including the AzureTenant, AzureClientId, AzureClientSecret and Resource.

Authenticating as an ISU

To authenticate as an ISU, you must first create either an API Client or an API Client for Integrations, as described in Creating a Custom API Client Application. You can create either of these clients using the JWT bearer grant type.

After you set the appropriate properties, you are ready to connect.

API Client for Integrations

  • ConnectionType and related properties.
  • AuthScheme: OAuthISU.
  • OAuthClientId: The Client ID obtained from the View API Client page.
  • OAuthClientSecret: The Client Secret obtained from the View API Client page.
  • OAuthRefreshToken: The refresh token obtained from the Manage Refresh Tokens for Integrations page.
  • Tenant: The tenant for the account.
  • BaseURL: The base URL for the REST API Endpoint in the View API Clients page.

API Client (JWT)

  • ConnectionType and related properties.
  • AuthScheme: OAuthJWT.
  • OAuthJWTCertType: The certificate type. If you created the certificate with keytool or openssl pkcs12, this should be PFXFILE.
  • OAuthJWTCert: The path of the certificate file you created.
  • OAuthJWTCertPassword: The password of the certificate file you created.
  • OAuthJWTIssuer: The Client ID obtained from the View API Client page.
  • OAuthJWTSubject: The username of the ISU you are using.
  • Tenant: The tenant for the account.
  • BaseURL: The base URL for the REST API Endpoint in the View API Clients page.

SOAP API

Connections using the SOAP API support all the same authentication schemes that the WQL and reporting services do. They also support Basic authentication, which does not require configuring a custom API client.

To use Basic authentication, set these connection parameters:

  • ConnectionType: SOAP.
  • AuthScheme: Basic.
  • User: The Workday user account name.
  • Password: The Workday user's password.
  • Tenant: The tenant for the account.
  • BaseURL: The base URL for the REST API Endpoint in the View API Clients page.

Other authentication methods are configured the same way as for the WQL and reporting services.
