Custom Credentials

When to Use a Custom OAuth App

Creating a custom OAuth app is required in all cases when using OAuth 2.0.

Desktop Authentication with a Custom OAuth App

Follow the steps below to authenticate with the credentials for a custom OAuth app. See Creating a Custom OAuth App for more information.

Get and Refresh the OAuth Access Token

After setting the following, you are ready to connect:

  • OAuthClientId: Set this to the client Id assigned when you registered your app.
  • OAuthClientSecret: Set this to the client secret assigned when you registered your app.
  • CallbackURL: Set this to the Callback defined when you registered your app.
  • Url: Set this to the URL of your service instance.
  • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
When you connect the driver opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The driver then completes the OAuth process:
  1. Extracts the access token from the callback URL and authenticates requests.
  2. Refreshes the access token when it expires.
  3. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.

Get an OAuth Access Token

Set the following connection properties to obtain the OAuthAccessToken:

  • OAuthClientId: Set this to the Client Id in your app settings.
  • OAuthClientSecret: Set this to the Client Secret in your app settings.
  • CallbackURL: Set this to the Callback defined when you registered your app.
  • Url: Set this to the URL of your service instance.

You can then call stored procedures to complete the OAuth exchange:

  1. Call the GetOAuthAuthorizationURL stored procedure. Set the CallbackURL input to the Callback you specified in your app settings.

    The stored procedure returns the URL to 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 Verifier input to the "code" parameter in the query string of the callback URL.

Refresh the OAuth Access Token

You can set InitiateOAuth to REFRESH to automatically refresh the OAuth access token when it expires, or you can call the RefreshOAuthAccessToken stored procedure to refresh the token manually.

Automatic Refresh

To refresh the token with InitiateOAuth, set the following on the first data connection:

  • OAuthAccessToken: Set this to the access token returned by GetOAuthAccessToken.
  • InitiateOAuth: Set this to REFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
  • OAuthSettingsLocation: Set this to the path where the driver will save the OAuth values, to be persisted across connections.
  • OAuthClientId: Set this to the Client Id in your app settings.
  • OAuthClientSecret: Set this to the Client Secret in your app settings.
  • OAuthRefreshToken: Set this to the refresh token returned by GetOAuthAccessToken.
  • Url: Set this to the URL of your service instance.

On subsequent data connections, set the following:

  • InitiateOAuth
  • OAuthSettingsLocation
  • Url: Set this to the URL of your service instance.

Manual Refresh

You can use the RefreshOAuthAccessToken stored procedure to manually refresh the OAuthAccessToken. Call the stored procedure after the ExpiresIn parameter value returned by GetOAuthAccessToken has elapsed. You need the following connection properties to be set:

  • OAuthClientId: Set this to the Client Id in your app settings.
  • OAuthClientSecret: Set this to the Client Secret in your app settings.

You can then call RefreshOAuthAccessToken with the following parameter set:
