Establishing a Connection
Authenticate via OAuth Authentication
When to Create a Custom OAuth App
Web Applications
You need to create a custom OAuth app in the web flow.
Desktop Applications
Creating a custom OAuth app is optional as the provider is already registered with LinkedIn and you can connect with its embedded credentials. You might want to create a custom OAuth app to change the information displayed when users log into the LinkedIn OAuth endpoint to grant permissions to the provider.
Headless Machines
Creating a custom OAuth app is optional to authenticate a headless machine; the provider is already registered with LinkedIn and you can connect with its embedded credentials. In the headless OAuth flow, users need to authenticate via a browser on another machine. You might want to create a custom OAuth app to change the information displayed when users log into the LinkedIn OAuth endpoint to grant permissions to the provider.
Custom Credentials
When to Create a Custom OAuth App
You might want to create a custom OAuth app to change the information displayed when users log into the LinkedIn OAuth endpoint to grant permissions to the provider.
Desktop Authentication with a Custom OAuth App
Follow the steps below to authenticate with the credentials for a custom OAuth app.
Get 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 redirect URI defined when you registered your app.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- Extracts the access token from the callback URL and authenticates requests.
- Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
Web Authentication with a Custom OAuth App
When connecting via a Web application, you need to register a custom OAuth app with LinkedIn. You can then use the provider to get and manage the OAuth token values.
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.
You can then call stored procedures to complete the OAuth exchange:
- Call the GetOAuthAuthorizationURL stored procedure. Set the AuthMode input to WEB and set the CallbackURL input to the Redirect URI you specified in your app settings. The stored procedure returns the URL to the OAuth endpoint.
- Log in and authorize the application. You are redirected back to the callback URL.
- 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.
Connecting Through a Firewall or Proxy
HTTP Proxies
To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.
In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.
Other Proxies
Set the following properties:
- To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
- To tunnel the connection, set FirewallType to TUNNEL.
- To authenticate, specify FirewallUser and FirewallPassword.
- To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.
Troubleshooting the Connection
To show provider activity from query execution to network traffic, use Logfile and Verbosity. The examples of common connection errors below show how to use these properties to get more context. Contact the support team for help tracing the source of an error or circumventing a performance issue.
- Authentication errors: Typically, recording a Logfile at Verbosity 4 is necessary to get full details on an authentication error.
- Queries time out: A server that takes too long to respond will exceed the provider's client-side timeout. Often, setting the Timeout property to a higher value will avoid a connection error. Another option is to disable the timeout by setting the property to 0. Setting Verbosity to 2 will show where the time is being spent.
