# Connect the LinkedIn inbox

LinkedIn grants inbox access separately from posting. Connect it once for each LinkedIn Page to read and answer comments on the Page's posts in the Social Inbox.

## Why it's a separate step

LinkedIn gives apps permission to post and permission to read comments separately. Connecting a LinkedIn Page for posting doesn't let Heropost see its comments. **Connect inbox** asks LinkedIn for that second permission, once for each Page. After that, comments on the Page's posts appear in the [Social Inbox](/docs/analytics/social-inbox/), and you can answer them there.

The inbox covers LinkedIn **Pages**. **Connect inbox** also appears on personal profiles, but the access it asks LinkedIn for is for Pages you manage.

## Before you start

- The LinkedIn Page is connected in Heropost. See [Connect LinkedIn](/docs/networks/linkedin/).
- You're an admin of the Page on LinkedIn.
- You can open the workspace's **Accounts** page.

## Connect the inbox

1. Click your **workspace name** at the top of Heropost, then **Accounts**.
2. On the LinkedIn Page, click **⋮**, then **Connect inbox**.
3. The tab goes to LinkedIn. Sign in if LinkedIn asks, and allow access.
4. LinkedIn sends you back to Heropost, which shows "Connecting LinkedIn inbox…", then **LinkedIn inbox connected**: "Comments on your LinkedIn page posts will appear in the Social Inbox after the next sync."
5. Press **Go to Social Inbox**. Comments arrive within the hour.

Repeat for each LinkedIn Page.

**On a phone:** on the **Accounts** list, tap the account's **⋮** button, then **Connect inbox**.

## What you get

- **Comments** on the Page's 10 most recently updated posts, up to 50 per post, in the **Comments** tab.
- **Replies:** your answer is posted as a new comment on the post.
- **How often:** Heropost checks LinkedIn at most once an hour per Page.
- **Not included:** LinkedIn mentions and messages, and likes.

## Things to know

- **There's no "connected" badge.** **Connect inbox** stays in the menu after you connect. Running it again replaces the connection.
- **If LinkedIn comments stop arriving,** LinkedIn's access may have ended. Heropost doesn't show a warning: run **Connect inbox** again.
- **Posting and the inbox are separate.** **Reconnect** in the same menu renews posting only. **Connect inbox** renews the inbox only.

## If it doesn't work

| What you see | What it means | What to do |
|---|---|---|
| "LinkedIn inbox app is not configured" | The LinkedIn inbox isn't available right now. | [Contact support](/docs/troubleshooting/get-help/). |
| **Could not connect LinkedIn inbox** with LinkedIn's own message | You canceled or refused on LinkedIn's page, or LinkedIn stopped the sign-in. | Press **Back to Social Accounts** and try **Connect inbox** again. Allow access on LinkedIn. |
| **Could not connect LinkedIn inbox**: "Missing authorization code" or "Invalid account reference in callback" | The return from LinkedIn was incomplete, for example after reloading or reopening that page. | Press **Back to Social Accounts** and start again from **Connect inbox**. |
| **Could not connect LinkedIn inbox**: "The server could not complete the connection" or "An unexpected error occurred while processing your request." | Heropost couldn't finish the connection with LinkedIn. | Try again. Make sure you're an admin of the Page on LinkedIn. If it repeats, [contact support](/docs/troubleshooting/get-help/). |
| Connected, but no LinkedIn comments | No new comments on the 10 most recently updated posts yet, the next check hasn't run, or it was connected on a personal profile. | Wait up to an hour and press refresh in the Social Inbox. Connect the inbox on the Page. |

## Questions

**Do I need to do this for every LinkedIn Page?**

Yes. Each Page is connected separately, from its own **⋮** menu.


**Does it work for my personal LinkedIn profile?**

The LinkedIn inbox is for Pages. Personal profiles can still post through Heropost.


**Can I answer LinkedIn messages?**

No. The Social Inbox shows comments on your Page's posts only.
