The LinkedIn module lets your AI agent publish thought-leadership posts, share business updates, and grow your professional network — all on autopilot. LinkedIn's API requires you to create a developer app and generate a personal access token scoped to w_member_social (the permission to post on your behalf).

This guide walks you through every step: creating the app, requesting the right product, generating a token, and entering your credentials into AgentGrow.

What You Will Need

FieldWhat it is
LINKEDIN_PAGE_URLThe URL of your LinkedIn personal profile (e.g. https://www.linkedin.com/in/yourname/)
LINKEDIN_ACCESS_TOKENAn OAuth access token that authorizes your agent to post on your LinkedIn profile
LinkedIn posting works on your personal profile — the same profile where you network with peers, share articles, and build your professional brand. Your agent posts as you, not as a company page.

Prerequisites

Part 1 — Create a LinkedIn App

LinkedIn requires you to have a developer app registered in their portal before you can generate an access token. This is a one-time setup that takes about five minutes.

1

Go to the LinkedIn Developer Portal

Open linkedin.com/developers in your browser. Sign in with your LinkedIn account if prompted.

2

Create a new app

Click Create app (top-right or the prominent button on the page). Fill in the required fields:

Click Create app.

3

Request the "Share on LinkedIn" product

After your app is created, go to the Products tab inside your app settings. You will see a list of available LinkedIn API products. Find "Share on LinkedIn" and click Request access.

Products tab → Share on LinkedIn → Request access

LinkedIn will review your request. In most cases, the Share on LinkedIn product is approved automatically within a few seconds — the page will refresh and show it as Added. This product grants the w_member_social scope that lets your agent post on your behalf.

Note: Also look for "Sign In with LinkedIn using OpenID Connect" and request access if available. This adds the openid, profile, and email scopes, which are required alongside w_member_social when generating a token via the OAuth tool.
4

Verify your app

Go to the Settings tab of your app. Under App settings, click Verify next to the Company Page you associated. LinkedIn will send a verification request to the admins of that Company Page (which is you, if you own the page). Approve the verification from the notification in your LinkedIn account.

Verification links the app to your organization. It does not change what your agent can post or who it posts as — your agent always posts on your personal profile.

Part 2 — Get an Access Token

LinkedIn provides a built-in OAuth token generator inside the Developer Portal. This is the easiest way to get a personal access token without writing any code.

1

Add the OAuth redirect URI

In your app, go to the Auth tab. Under OAuth 2.0 settings, click the pencil icon next to Authorized redirect URLs for your app. Add this exact URL:

https://www.linkedin.com/developers/tools/oauth/redirect

Click Update to save.

2

Open the OAuth Token Generator

In the left navigation of the Developer Portal, click Tools → OAuth token tools. (Direct URL: linkedin.com/developers/tools/oauth/token-generator.) Select your app from the dropdown.

3

Select the required scopes

In the Member token tools section, check all four scopes:

OAuth Token Tools → Member token tools → select scopes → Request access token
4

Request and authorize the token

Click Request access token. LinkedIn will redirect you to an authorization page asking you to grant the app the selected permissions. Click Allow.

You will be redirected back to the OAuth token tools page and your access token will be shown:

AQX...

Access tokens are long strings starting with AQX or similar. Copy the entire token.

Important — Token expiry: LinkedIn access tokens expire in approximately 60 days. Your agent will stop being able to post after the token expires. You will need to repeat Part 2 to generate a new token and update it in your Integrations page. AgentGrow will notify you in the dashboard when your token is approaching expiry.

This token is your LINKEDIN_ACCESS_TOKEN. Keep it private — it grants the ability to post on your LinkedIn profile.

Part 3 — Enter Credentials in AgentGrow

1

Find your LinkedIn profile URL

Go to your LinkedIn profile. Copy the URL from your browser's address bar. It will look like one of these:

https://www.linkedin.com/in/yourname/

This is your LINKEDIN_PAGE_URL. Use your full profile URL including the trailing slash.

2

Open your Integrations page

Log in to your AgentGrow dashboard at agentgrow.io/user/integrations.

3

Configure the LinkedIn module

Find the LinkedIn module card and click Configure (or Reconfigure if you are updating an existing token). Enter:

Click Save & Restart Agent. Your agent pod will restart in about 30 seconds with the new credentials loaded.

4

Verify the connection

After the restart, your agent is ready to post on LinkedIn. Check the Dashboard activity feed for your first LinkedIn post, or send your agent a Telegram message asking it to publish a test post.

Your agent creates professional, on-brand posts tailored to your industry and audience. It uses your business profile and goals (set up during CBO onboarding) to decide what to write about.

Token Renewal — What to Do When Your Token Expires

LinkedIn access tokens last approximately 60 days. When your token expires, your agent will log an error and LinkedIn posts will stop. Here is how to renew it:

1

Generate a new token

Return to linkedin.com/developers/tools/oauth/token-generator, select your app, check the same four scopes (openid, profile, email, w_member_social), and click Request access token. Authorize again and copy the new token.

2

Update AgentGrow

Go to agentgrow.io/user/integrations, click Reconfigure on the LinkedIn module, paste your new access token, and click Save & Restart Agent.

3

Set a calendar reminder

Set a repeating reminder for every 50 days so you renew the token before it expires. LinkedIn does not currently offer a way to automatically refresh member tokens without additional OAuth infrastructure.

Pro tip: LinkedIn is working on longer-lived tokens for verified apps. Keep an eye on the Products tab of your app — if "Marketing Developer Platform" becomes available for your use case, it may unlock refresh tokens that last significantly longer.

Troubleshooting

I do not see "Share on LinkedIn" in the Products tab

Make sure your app is fully created and verified. Some products only appear after:

Try refreshing the Products tab. If the product still does not appear, log out of the Developer Portal and log back in.

The OAuth token tool says "insufficient permissions"

This means w_member_social was not granted to your app. Go to the Products tab and verify that Share on LinkedIn shows as Added. If it still shows Request access, click it and wait for approval. Approval is usually instant, but can occasionally take a few minutes.

My token was generated but the agent cannot post

Double-check that:

If everything looks correct, generate a fresh token and reconfigure.

My agent posted but I cannot see it on LinkedIn

Check the Recent Activity section of your LinkedIn profile (click your profile photo → View profile → scroll down to Activity). LinkedIn may occasionally take a minute or two to index and display new posts in the feed. If the post does not appear after five minutes:

How do I check how many days are left on my token?

LinkedIn does not display the expiry date on the token tool page after generation. The safest approach is to note the date you generated the token and set a 50-day reminder to renew. Alternatively, you can test your current token by making a request to the LinkedIn API:

https://api.linkedin.com/v2/userinfo

Use your browser's developer tools or a tool like Postman to send a GET request with the header Authorization: Bearer YOUR_TOKEN. A successful response means the token is still valid.
