Create linkedin is a POST on /api/v1/linkedin, part of the linkedin family of the MakeHybrid Unlimited 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.
This family passes a request through to LinkedIn's own surface, so what comes back is shaped by LinkedIn rather than by us.
The request
curl -X POST "https://makehybrid.com/api/v1/linkedin" \
-H "X-API-KEY: $MAKEHYBRID_KEY" \
-H "content-type: application/json" \
-d '{}'
What comes back when it does not work
- 401 — the key is missing, wrong or revoked.
- 402 — the plan is not paid for. Premium 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/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.
Which plan it is on
The Unlimited plan, on /v1. $3 a month, flat, for as many connected LinkedIn accounts as you like, with a 30-day trial.
