ADO.NET Provider for Salesforce

Build 23.0.8839

Establishing a Connection

Connecting to Salesforce

By default, the provider connects to production environments. Set UseSandbox to true to use a Salesforce sandbox account. If you are using user/password authentication, ensure that you specify a sandbox username in User.

Authenticating to Salesforce

User Credentials and a Security Token

Set the AuthScheme to Basic and set the User and Password to your login credentials. Additionally, set the SecurityToken. By default, the SecurityToken is required, but you can make it optional by configuring a range of trusted IP addresses in Salesforce.

To disable the security token:

  1. Log in to Salesforce and enter Network Access in the Quick Find box in the setup section.
  2. Add your IP address to the list of trusted IP addresses.

To obtain the security token:

  1. Open the personal information page on Salesforce.com.
  2. Click the link to reset your security token. The token will be emailed to you.
  3. Specify the security token in the SecurityToken connection property or append it to the Password.

OAuth

AuthScheme must be set to OAuth in all user account flows.

Desktop Applications

CData provides an embedded OAuth application that simplifies OAuth desktop Authentication. Alternatively, you can create a custom application. See Creating a Custom OAuth App for information on creating custom applications and reasons for doing so.

For authentication, the only difference between the two methods is that you must set two additional connection properties when using custom OAuth applications.

After setting the following connection properties, you are ready to connect:

  • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
  • OAuthClientId: (custom applications only) Set to the Client ID in your application settings.
  • OAuthClientSecret: (custom applications only) Set to the Client Secret in your application settings.

When you connect, the provider opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The provider then completes the OAuth process as follows:

  • Extracts the access token from the callback URL.
  • Obtains a new access token when the old one expires.
  • Saves OAuth values in OAuthSettingsLocation so that they persist across connections.

Web Applications

When connecting via a web application, you need to register a custom OAuth application with Salesforce. See Creating a Custom OAuth App for more information. You can then use the driver to get and manage the OAuth token values.

First, get an OAuthAccessToken by setting the following connection properties:

  • OAuthClientId: Set to the client Id in your application settings.
  • OAuthClientSecret: Set to the client secret in your application settings.

Then call stored procedures to complete the OAuth exchange:

  1. Call the GetOAuthAuthorizationUrl stored procedure. Set the CallbackURL input to the callback URL you specified in your application settings. If necessary, set the Scope parameter to request custom permissions. The stored procedure returns the URL of the OAuth endpoint.
  2. Open the URL, log in, and authorize the application. You are redirected back to the callback URL.
  3. Call the GetOAuthAccessToken stored procedure. Set the AuthMode input to WEB. Set the Verifier input to the "code" parameter in the query string of the callback URL. If necessary, set the Scope parameter to request custom permissions.

After you have obtained the access and refresh tokens, you can connect to data and refresh the OAuth access token either automatically or manually.

Automatic Refresh of the OAuth Access Token

To have the driver automatically refresh the OAuth access token, set the following on the first data connection:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthClientId: Set this to the client Id in your application settings.
  • OAuthClientSecret: Set this to the client secret in your application settings.
  • OAuthAccessToken: Set this to the access token returned by GetOAuthAccessToken.
  • OAuthRefreshToken: Set this to the refresh token returned by GetOAuthAccessToken.
  • OAuthSettingsLocation: Set this to the location where the provider saves the OAuth token values, which persist across connections.
On subsequent data connections, the values for OAuthAccessToken and OAuthRefreshToken are taken from OAuthSettingsLocation.

Manual Refresh of the OAuth Access Token

The only value needed to manually refresh the OAuth access token when connecting to data is the OAuth refresh token.

Use the RefreshOAuthAccessToken stored procedure to manually refresh the OAuthAccessToken after the ExpiresIn parameter value returned by GetOAuthAccessToken has elapsed, then set the following connection properties:

  • OAuthClientId: Set this to the client Id in your application settings.
  • OAuthClientSecret: Set this to the client secret in your application settings.

Then call RefreshOAuthAccessToken with OAuthRefreshToken set to the OAuth refresh token returned by GetOAuthAccessToken. After the new tokens have been retrieved, open a new connection by setting the OAuthAccessToken property to the value returned by RefreshOAuthAccessToken.

Finally, store the OAuth refresh token so that you can use it to manually refresh the OAuth access token after it has expired.

Headless Machines

To configure the driver to use OAuth with a user account on a headless machine, you need to authenticate on another device that has an internet browser.

  1. Choose one of two options:

    • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
    • Option 2: Install the provider on a machine with a browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow, as described in "Transfer OAuth Settings" below.

  2. Then configure the provider to automatically refresh the access token on the headless machine.

Option 1: Obtain and Exchange a Verifier Code

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

Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.

  1. Choose one of these options:

    • If you are using the Embedded OAuth Application click Salesforce OAuth endpoint to open the endpoint in your browser.
    • If you are using a Custom OAuthd Application, create the Authorization URL by setting the following properties:
      • InitiateOAuth: Set to OFF.
      • OAuthClientId: Set to the client Id assigned when you registered your application.
      • OAuthClientSecret: Set to the client secret assigned when you registered your application.
      Then call the GetOAuthAuthorizationURL stored procedure with the appropriate CallbackURL. Open the URL returned by the stored procedure in a browser.

  2. Log in and grant permissions to the provider. You are then redirected to the callback URL, which contains the verifier code.
  3. Save the value of the verifier code. Later you will set this in the OAuthVerifier connection property.
Next, you need to exchange the OAuth verifier code for OAuth refresh and access tokens. Set the following properties:

On the headless machine, set the following connection properties to obtain the OAuth authentication values.

  • InitiateOAuth: Set this to REFRESH.
  • OAuthVerifier: Set this to the verifier code.
  • OAuthClientId: (custom applications only) Set this to the client Id in your custom OAuth application settings.
  • OAuthClientSecret: (custom applications only) Set this to the client secret in the custom OAuth application settings.
  • OAuthSettingsLocation: Set this to persist the encrypted OAuth authentication values to the specified location.

After the OAuth settings file is generated, you need to re-set the following properties to connect:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthClientId: (custom applications only) Set this to the client Id assigned when you registered your application.
  • OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
  • OAuthSettingsLocation: Set this to the location containing the encrypted OAuth authentication values. Make sure this location gives read and write permissions to the provider to enable the automatic refreshing of the access token.

Option 2: Transfer OAuth Settings

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

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

After you have successfully tested the connection, copy the OAuth settings file to your headless machine.

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

  • InitiateOAuth: Set this to REFRESH.
  • OAuthClientId: (custom applications only) Set this to the client Id assigned when you registered your application.
  • OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
  • OAuthSettingsLocation: Set this to the location of your OAuth settings file. Make sure this location gives read and write permissions to the provider to enable the automatic refreshing of the access token.

OAuth Password Grant

Follow these steps to set up the Password Grant option:

  1. Set the AuthScheme to OAuthPassword to perform authentication with the password grant type.
  2. Set all the properties specified in either the web or desktop authentication sections above.
  3. Set the User and Password to your login credentials, as well as the SecurityToken if required.

Note: If you have enabled Session Settings > Lock sessions to the IP address from which they originated, make sure that your IP address does not change while using the provider. If the IP changes during the usage of the provider, an "INVALID_SESSION_ID" error is returned from Salesforce and the provider will no longer be able to retrieve data. If you receive this error, ask your Salesforce administrator to disable this configuration or make sure to configure a static IP for the instance where you are using the provider. Then, reset the connection to continue using the provider. 

OAuthJWT Certificates

Set the AuthScheme to OAuthJWT.

OAuthJWT

To obtain the OAuthJWT consumer key:

  1. Log in to Salesforce.com.
  2. From Setup, enter Apps in the Quick Find box and then click the link to create an app. In the Connected Apps section of the resulting page, click New.
  3. Enter a name to be displayed to users when they log in to grant permissions to your app, along with a contact Email address.
  4. Click Enable OAuth Settings and enter a value in the Callback URL box. Set this value only to create the Connected App as it is required. It will not actually be needed for this type of authentication. The Callback URL is in the format: 
    http://localhost:8019/src/oauthCallback.rst
  5. Enable Use digital signatures.
  6. Upload your certificate.
  7. Select the scope of permissions that your app should request from the user.
  8. Click your app name to open a page with information about your app. The OAuth consumer key is displayed.

After creating your OAuth Application, set the following connection properties:

  • AuthScheme: Set to OAuthJWT.
  • InitiateOAuth: Set to GETANDREFRESH.
  • OAuthJWTCert: Set this to the JWT Certificate store.
  • OAuthJWTCertType: Set this to the type of the certificate store specified by OAuthJWTCert.
  • OAuthJWTCertPassword: Set this to the Password of the JWT Certificate store.
  • OAuthJWTIssuer: Set this to the OAuth Client ID.
  • OAuthJWTSubject: Set this to the username (email address) to the permitteed User Profile configured in the OAuth Connected App.

Note: This flow never issues a refresh token.

AzureAD

Set the AuthScheme to AzureAD. Use the following connection properties to connect to AzureAD:

  • SSOExchangeUrl: The Salesforce OAuth 2.0 token endpoint for the identity provider. This can be found in the Salesforce account settings by navigating to Administration Setup > Security Controls > SAML Single Sign-On Settings and then choosing the desired organization.

Note that this configuration requires two AAD applications: the "Salesforce" application used for single sign-on, and a separate "connector" application with user_impersonation permission on the "Salesforce" application. You must also specify the OAuth connection properties:

  • OAuthClientId: The application Id of the connector application, listed in the Overview section of the app registration.
  • OAuthClientSecret: The client secret value of the connector application. Azure AD displays this when you create a new client secret.

Use the following SSOProperties to authenticate to AzureAD:

  • Resource: The application Id URI of the Salesforce application, listed in the Overview section of the app registration. In most cases this is the URL of your custom Salesforce domain.
  • AzureTenant: The Id of the Azure AD tenant where the applications are registered.

The following is an example connection string: 

AuthScheme=AzureAD;InitiateOAuth=GETANDREFRESH;OAuthClientId=3ea1c786-d527-4399-8c3b-2e3696ae4b48;OauthClientSecret=xxx;SSOProperties='Resource=https://example.my.salesforce.com;AzureTenant=6ee709df-9de0-4cdf-10e6b7a51d95';

Okta

Set the AuthScheme to Okta. Use the following connection properties to connect to Okta:

  • User: Set this to the Okta user.
  • Password: Set this to Okta password for the user.
  • SSOLoginURL: Set this to the login url used by the SSO provider.
  • SSOExchangeUrl: The Salesforce OAuth 2.0 token endpoint for the identity provider. This can be found in the Salesforce account settings by navigating to Administration Setup > Security Controls > SAML Single Sign-On Settings and then choosing the desired organization.
In SSOProperties, when required, set these input parameters:
  • APIToken (optional): Set this to the API Token that the customer created from the Okta org. You should use this when authenticating a user via a trusted application or proxy that overrides OKTA client request context.
  • MFAType (optional): Set this only in case you have configured MFA flow. Currently we support only the following types: OktaVerify, Email, and SMS.
  • MFAPassCode (optional): Set this only in case you have configured MFA flow. If this is set to empty/invalid the driver initially issues a MFA challenge that triggers the platform to send you a one-time password on your device or email, based on the configured MFA type. You need to re-issue another connection where the retrieved one-time password value is passed to MFAPassCode connection property.

The following is an example connection string: 

AuthScheme=PingFederate;User=PingFederateUserName;Password=PingFederatePassword;URL='http://sharepointserver/mysite';

OneLogin

  • Password: Set this to OneLogin password for the user.
  • SSOExchangeUrl: The Salesforce OAuth 2.0 token endpoint for the identity provider. This can be found in the Salesforce account settings by navigating to Administration Setup > Security Controls > SAML Single Sign-On Settings and then choosing the desired organization.
You need the following SSOProperties to authenticate to OneLogin:

  • OAuthClientId: Set to the OAuthClientId, which you can obtain by selecting Developers > API Credentials > Credential > ClientId.
  • OAuthClientSecret: Set to the OAuthClientSecret, which you can obtain by selecting Developers > API Credentials > Credential > ClientSecret.
  • Subdomain: Set to the subdomain of the OneLogin user accessing the SSO app. For example, if your OneLogin URL is splinkly.onelogin.com, enter splinkly as the subdomain value.
  • AppId: Set to the Id of the SSO app.
  • Region (optional): Set to the region your OneLogin account resides in. The OneLogin API operates in multiple regions and this property is used to find the correct domain. It can take one of the following values:
    • US (default)
    • EU

The following is an example connection string: 

AuthScheme=OneLogin;User=OneLoginUserName;Password=OneLoginPassword;SSOProperties='OAuthClientID=3fc8394584f153ce3b7924d9cd4f686443a52b;OAuthClientSecret=ca9257fd5cc3277abb5818cea28c06fe9b3b285d73d06;Subdomain=OneLoginSubDomain;AppId=1433920';
