Read the AI inbox is a GET on /linkedin/webhooks/inbox, part of the webhooks family of the MakeHybrid API. Every request carries your own key in an X-API-KEY header; the key decides which organisation you are and therefore which LinkedIn accounts you may name.
Webhooks are the difference between knowing and polling. Verify the signature on every delivery and treat a repeat of the same event as normal.
The request
curl -X GET "https://makehybrid.com/linkedin/webhooks/inbox" \ -H "X-API-KEY: $MAKEHYBRID_KEY"
What comes back when it does not work
- 401 — the key is missing, wrong or revoked.
- 402 — the plan is not paid for. The MakeHybrid API answers this once a trial has ended.
- 404 — either the thing is not there, or the account id is not yours. The two are deliberately the same answer, so ids cannot be probed.
- 429 — too many requests, or LinkedIn throttling the account. Waiting is the only fix; trying again sooner extends it.
- 503 — LinkedIn or the hop in front of it did not answer. The body carries the bare status it saw.
Every error is JSON in the same shape: {"type":"errors/<code>","status":<n>,"detail":"..."} — so one handler covers all of them, and the detail is written to be shown to a person.
Asking an assistant instead
This operation is also an MCP tool. Paste https://makehybrid.com/linkedin/mcp/<your API key> into Claude, ChatGPT or any assistant that speaks MCP and ask for what you want in plain English — the assistant picks the call, fills in the ids and reads the answer back to you. There is nothing to install.
In a project room
In a project room, tick MakeHybrid under Can use for an AI agent of your own, and it calls Read the AI inbox as a tool whenever the conversation needs it, on the LinkedIn accounts your organization connected. Everyone in the room sees what it asked and what came back. Ask in plain words; here the agent is called @scout:
- @scout which webhooks do we have, and did their last deliveries succeed?
Questions people ask
Can an AI agent call Read the AI inbox for me?
Yes. Any assistant that speaks MCP can, through the address above, and so can an AI agent of your own in a project room with MakeHybrid ticked. The built-in agents of a room cannot: they advise, and they do not hold your LinkedIn key.
Does it work outside a room, from my own code?
Yes. The request above is the same operation an AI agent's tool calls, with the same answer and the same errors. Your key decides which LinkedIn accounts it may name, whichever way you come in.
Does it work in a room under my own brand?
Yes. On a white-label address the tool is listed under your product's name, and it reaches the same accounts under the same rules.
Which plan it is on
The MakeHybrid API, on /linkedin. $9 per connected LinkedIn account per month, $7 from ten accounts and $5 from a thousand, with a 30-day trial covering one account.
