Sync my LinkedIn Inbox

Why manage your LinkedIn inbox outside the app

The Unibox gathers the LinkedIn conversations of every seat on your account, and Gojiberry flags which replies are interested. Reaching it through the API or the MCP server puts those replies where you already work:

Never miss a hot reply. Pull interested, unread threads into your CRM, Slack, or a daily digest, so a “let’s talk” doesn’t wait in a tab nobody opened.
Keep your CRM complete. Copy every LinkedIn conversation onto the matching contact or deal, next to emails and calls, so the whole team sees the history.
Triage in seconds from your AI assistant. Ask ChatGPT, Claude, or Grok “Who replied this week and what do they want?” and get a summary instead of reading thread by thread.
Reply faster. Let your assistant draft answers from the conversation, review them, and send them from the right LinkedIn seat without switching tools.
Cover several seats at once. Managers and agencies follow every seat’s replies in one place, and act for a team member with impersonation.

With the MCP server you don’t write code: the assistant calls the tools named in each step below for you. With the API, you make the calls yourself.

Sync the inbox

A sync is two calls. List the conversations, then read the messages in each one. Both responses are a page: data is the rows, and total, page, limit, and totalPages describe that page. Send Authorization: Bearer YOUR_API_KEY. The base URL is https://ext.gojiberry.ai.

List threads

GET /v1/unibox/threads returns LinkedIn conversations, newest activity first. Omit seatId to include every LinkedIn seat on the account, or pass one seat id to sync that seat only. Pass dateFrom as an ISO date to keep threads whose last message is on or after that time. interested, seen, and attendeeFullName narrow the list further.MCP tool: list_unibox_threads, with the same filters. Try asking: “Show my unread LinkedIn threads from interested leads this week.”

curl -H "Authorization: Bearer YOUR_API_KEY" \
  "https://ext.gojiberry.ai/v1/unibox/threads?limit=20&order=DESC"

{
  "data": [
    {
      "id": 4812,
      "lastMessage": "Thanks, let's talk next week.",
      "lastMessageDate": "2026-10-13T18:04:11.000Z",
      "lastMessageFullName": "Jane Doe",
      "attendeeFullName": "Jane Doe",
      "attendeeUrn": "urn:li:fsd_profile:ACoAAA...",
      "seen": false,
      "interested": true,
      "contactId": 90210,
      "seatId": 14,
      "userId": 17
    }
  ],
  "total": 128,
  "page": 1,
  "limit": 20,
  "totalPages": 7
}

Store id. That is the thread id the next calls expect. It is not the LinkedIn conversationUrn.contactId is set when the attendee matches a Gojiberry contact, and is null otherwise. seen is whether the thread has been opened. interested is the sentiment of the latest reply, and stays null until a reply has been classified. Walk page from 1 through totalPages.

Read the messages in a thread

GET /v1/unibox/threads/{threadId}/messages returns that thread’s messages, oldest first. threadId is the id from the previous call.MCP tool: get_unibox_thread_messages. Try asking: “Summarize my conversation with Jane Doe.”

curl -H "Authorization: Bearer YOUR_API_KEY" \
  "https://ext.gojiberry.ai/v1/unibox/threads/4812/messages?limit=50"

{
  "data": [
    {
      "id": 99001,
      "threadId": 4812,
      "senderFullName": "Jane Doe",
      "senderIsSelf": false,
      "content": "Thanks, let's talk next week.",
      "deliveredAt": "2026-10-13T18:04:11.000Z",
      "createdAt": "2026-10-13T18:04:20.000Z",
      "attachments": [
        {
          "id": "att-1",
          "name": "notes.pdf",
          "type": "file",
          "size": 20480,
          "url": "https://www.linkedin.com/..."
        }
      ]
    }
  ],
  "total": 6,
  "page": 1,
  "limit": 50,
  "totalPages": 1
}

senderIsSelf is true when the message was sent from your LinkedIn seat, and false when the other person sent it. deliveredAt is when LinkedIn delivered the message. createdAt is when Gojiberry stored the row, which can be later for older history.To fetch an attachment’s file, pass the message id and the attachment id to Download an attachment. This call has no MCP tool yet.On the next sync, pass the newest lastMessageDate you stored as dateFrom so you only pull threads that changed.

Reply (optional)

POST /v1/unibox/messages/send-message sends a LinkedIn message in the thread, from the thread’s seat. chatId is the thread id. You can attach a file or a voiceMessage as multipart fields.MCP tool: send_unibox_message. Files and voice messages are passed as base64. Try asking: “Draft a reply to Jane proposing Tuesday at 10am, and send it once I approve.”

curl -X POST -H "Authorization: Bearer YOUR_API_KEY" \
  -F chatId=4812 \
  -F message="Great, does Tuesday at 10am work for you?" \
  "https://ext.gojiberry.ai/v1/unibox/messages/send-message"

The response is the stored message, in the same format as in the previous step.

This sends a real message to a real person and cannot be undone. When an assistant drafts replies for you, review them before you let it send.

Every field is listed on Get threads, Get messages, and Send a message.
