Setting LinkedIn API Keys
After installing the Ultimate LinkedIn Plugin, you will need to set your LinkedIn API Keys.
Go to Settings > Ultimate LinkedIn Integration > General tab
You will need to fill in these 2 fields: Your LinkedIn API Key and Your LinkedIn API Secret Key
These API Keys can be copied from your LinkedIn Developer tools under My Apps.
Note: If you have no LinkedIn API Key yet, please follow the instructions below on how to create an application in LinkedIn. Otherwise, proceed to the final step – Setting OAuth 2.0 Redirect URL.
Click Save Changes button once done. You can leave the other fields to its default settings.
How to create an application in LinkedIn
API keys are required to use the plugin. Here’s how you can create an application in LinkedIn Developer’s site:
Go to LinkedIn Developer’s site here: https://www.linkedin.com/developer/apps
Click the yellow button Create Application.
Once done, you will be redirected to the application you just created where you see the API Keys (see screenshot under Setting LinkedIn API Keys).
Setting OAuth 2.0 Redirect URL
After setting the API Keys, the final step you have to do is to set the OAuth 2.0 Redirect URL. This field is just below the API Keys.
Set the URL to point to the wp-login.php page, e.g. yoursitename.com/wp-login.php (see screenshot below). Just click Add button after entering the redirect URL and click Update button once done, then you should be good to go!
Note: If you don’t set this field, you will get an “Invalid Redirect URL” error message.
