LinkedIn login

Let people sign in and register with their LinkedIn account. Create a LinkedIn app with the OpenID Connect product and paste its Client ID and Client Secret into Auth Settings.

With LinkedIn login on, the login and registration pages show a LinkedIn button. You create an app in the LinkedIn Developer portal, add the Sign In with LinkedIn using OpenID Connect product, then paste the Client ID and Client Secret into Auth Settings. No .env changes are needed.

MagicPost uses LinkedIn’s OpenID Connect sign-in and asks for the openid, profile and email scopes. LinkedIn must return an email address, otherwise the sign-in is refused.

This is sign-in for your own users. To publish to a LinkedIn profile or Page you use the credentials under Admin → Publishing → Platforms, which need different LinkedIn products. See LinkedIn. Setting up this login does not connect a channel.

​

Before you start

• You can sign in to the MagicPost admin panel.
• You have a LinkedIn account that can use the LinkedIn Developer portal.
• You have a LinkedIn Page to associate with the app. LinkedIn asks for one when you create an app.
• Your site runs on its public https address.

​

Step 1. Copy the Callback URL

1. Open Auth Settings

   Go to Admin → Backend Settings → Auth Settings and scroll to the LinkedIn section.

2. Copy the Callback URL

   Copy the value of the read-only Callback URL field. It looks like https://your-domain.com/auth/linkedin/callback. You paste it into LinkedIn next.

​

Step 2. Create the LinkedIn app

1. Create the app

   Go to linkedin.com/developers/apps and click Create app. Enter an App name, select the LinkedIn Page to associate, add a logo, accept the terms and create the app.

2. Add the OpenID Connect product

   Open the Products tab and request Sign In with LinkedIn using OpenID Connect. This product is what grants the openid, profile and email scopes. They cannot be added by hand. Do not pick the older sign-in product.

3. Add the redirect URL

   Open the Auth tab. Under OAuth 2.0 settings, next to Authorized redirect URLs for your app, click the edit icon and choose Add redirect URL. Paste the Callback URL from Step 1 and save.

4. Copy the credentials

   Still on the Auth tab, copy the Client ID and the Primary Client Secret from the application credentials.

​

Step 3. Configure MagicPost

1. Turn on the master switch

   On Admin → Backend Settings → Auth Settings, switch on Login via Social (oAuth). It saves as soon as you toggle it.

2. Enable LinkedIn and fill in the credentials

   In the LinkedIn section, switch on Enable LinkedIn Login and fill in:

   • LinkedIn API Key: the Client ID.
   • LinkedIn API Secret Key: the Client Secret.
   • LinkedIn Redirect URL: the same address as Callback URL.
3. Save

   Click Save. The toast reads Settings were saved successfully.

MagicPost field	LinkedIn value
LinkedIn API Key	Client ID
LinkedIn API Secret Key	Client Secret
LinkedIn Redirect URL	Authorized redirect URL. Must match exactly
Callback URL	Read-only. The value to register as the authorized redirect URL

​

Test it

1. Open your site’s login page in a private browser window.
2. Click LinkedIn under or continue with.
3. Approve the LinkedIn consent screen.
4. You land on the dashboard. The registration page offers the same button under or sign up with.

Troubleshooting

Symptom	Likely cause	Fix
LinkedIn says the redirect URL does not match	The address in the app differs from the one MagicPost sends	Make Authorized redirect URLs for your app, LinkedIn Redirect URL and Callback URL identical, including https and any language segment
LinkedIn reports an unauthorized scope	The OpenID Connect product is not on the app	Add Sign In with LinkedIn using OpenID Connect on the Products tab
Your social account did not share an email address, so we cannot sign you in.	The email scope is missing	Check that the OpenID Connect product is approved for the app
No LinkedIn button on the login page	Master switch off, Enable LinkedIn Login off, or the Client ID or secret is empty	Check all three, then save
That social login option is not available.	Same as above, reached by a direct link	Same fix
We could not complete the social login. Please try again.	Wrong Client Secret, redirect address mismatch, or the sign-in started and ended on different site addresses	Re-copy the secret, check the redirect address, and use one site address
Registration is currently closed, so a new account could not be created.	User Registration is off and no account has that email	Turn on User Registration under Admin → Backend Settings → Registration Settings, or create the user first
Your account is not active. Please contact support.	The matching account is banned or suspended	Reactivate the account in the admin panel
