Public API + n8n

What it does

One endpoint publishes a text post on your behalf, to one of two places:

• Your personal feed — just leave club_id out.
• A club you run — pass its club_id. You have to be the club’s owner or admin, the same rule as posting as the club in the app.

Get an API key

1. Open the Amator app and go to Settings › API keys.
2. Tap Create and give the key a name you will recognise later, e.g. “n8n”.
3. Copy the key straight away — it is shown only once. If you lose it, revoke it and create a new one.

Treat the key like a password: anyone who has it can post as you. You can revoke any key at any time on the same screen, and requests made with it are refused from then on.

The endpoint

POST https://api.amator.app/api/v1/public/posts

Send a JSON body and put the key in the X-API-KEY header (not Authorization: Bearer).

• content string — the post text, 1–2000 characters. Required.
• club_id uuid | null — the club to post as. Optional — without it the post goes to your personal feed.

Post to your personal feed

curl -X POST https://api.amator.app/api/v1/public/posts \
  -H "X-API-KEY: YOUR_API_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{"content":"Training moved to 19:00 tonight"}'

Post as a club

curl -X POST https://api.amator.app/api/v1/public/posts \
  -H "X-API-KEY: YOUR_API_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{"content":"Match day! Kick-off at 18:00","club_id":"00000000-0000-0000-0000-000000000000"}'

A successful post returns 201 with a link to it:

HTTP/1.1 201 Created

{
  "success": true,
  "data": {
    "id": "…",
    "destination": "club",
    "club_id": "00000000-0000-0000-0000-000000000000",
    "created_at": "2026-10-05T18:00:00.000Z",
    "url": "https://web.amator.app/posts/…"
  },
  "requestId": "…"
}

One post per hour, per destination

Every destination has its own hourly slot: your profile is one, and each club is another. Slots are never pooled — posting to one does not use up another, and a free slot elsewhere does not help a busy one.

• OK Your profile and club A in the same hour
• OK Clubs A, B and C in the same hour
• 429 A second post to club A within the hour — 429, even if your profile and the other clubs are free

When a slot is taken you get 429 with a Retry-After header (in seconds) and the details in the body:

HTTP/1.1 429 Too Many Requests
Retry-After: 2400

{
  "success": false,
  "error": {
    "code": "PUBLIC_API_RATE_LIMITED",
    "message": "This club already had its post this hour",
    "details": {
      "destination": "club",
      "club_id": "00000000-0000-0000-0000-000000000000",
      "retry_after_seconds": 2400,
      "next_allowed_at": "2026-10-05T19:00:00.000Z"
    }
  },
  "requestId": "…"
}

Wait at least Retry-After seconds, or until next_allowed_at, before posting to that destination again. Do not retry in a loop.

Other responses

• 400 FEED_POST_EMPTY
  The post text is empty or too long.
• 401 PUBLIC_API_KEY_INVALID
  The key is missing, unknown or revoked.
• 403 FEED_NOT_A_CAPTAIN
  You are not the owner or an admin of that club.
• 404 FEED_TEAM_NOT_FOUND
  There is no club with that club_id.
• 429 PUBLIC_API_RATE_LIMITED
  That destination already had a post this hour.
• 429 FEED_DAILY_LIMIT_REACHED
  The feed’s own limit of 40 posts a day has been reached.

Ready-made n8n workflow

Five nodes: a manual start, an Edit Fields node holding content and club_id, an If node that checks whether club_id is empty, and two HTTP Request nodes — one posts to your profile, the other to the club.

It starts with a manual trigger so you can test it right after importing. Once it works, replace Start with whatever should really kick it off — Schedule, RSS, a form — and map its output to the two fields.
