This is the OpenID Connect product

LinkedIn has two sign-in products. The older OAuth 2.0 one is closed to new applications; Memberside speaks Sign In with LinkedIn using OpenID Connect, which is the one you can still add. If you are following a guide that mentions r_liteprofile or r_emailaddress, it is describing the old product.

Create the app

1. Create a LinkedIn company page if you do not have one, and make sure you are an administrator. LinkedIn will not let you create an app without one, and this stops more people than any other step.

2. Open LinkedIn Developers and create an app, associating it with that page.

3. Verify the app from the link LinkedIn emails to the page administrator.

4. Open the Products tab and request Sign In with LinkedIn using OpenID Connect. It is granted immediately.

5. Open the Auth tab and add the redirect address under Authorized redirect URLs for your app: the string from Memberside → API Keys → Social Login → LinkedIn, which looks like https://yoursite.com/wp-json/memberside/v1/social/callback/linkedin.

6. Copy the Client ID and Client Secret from the same tab.

What to paste into Memberside

Under Memberside → API Keys → Social Login → LinkedIn:

Field	Value
Client ID	The Client ID
Client secret	The Client Secret
