Ur Next Door API Docs

The Ur Next Door API lets you publish to urnextdoor.com from code instead of the website or the app. You create a personal API key in Settings > API keys, give it to a script, an automation tool or an AI agent, and that tool can then create content for you: right now, or at a time you choose.

Every request acts as you. A key can never do more than you can do by hand on the website, and you can revoke it at any time.

What you can do with the API

• Create content: posts, questions, polls, MCQs, communities, Marketplace services and jobs.
• Schedule it: add scheduled_at to any create and it goes live later, from 5 minutes to 180 days ahead. Then list, reschedule, publish now or cancel.
• Upload images: send an image, including one an AI tool generated, as base64 JSON or a file upload, then use it as a featured image or in a gallery.
• Look things up: the communities you can post in, service categories, job options and places, so your tool never has to guess an id.
• See what happened: every key's activity shows up in Settings > Analytics.

Quickstart in three steps

1. Create a key. Sign in at urnextdoor.com, open Settings > API keys, create a key and copy it. It is shown only once. Step by step.

2. Store it in an environment variable named UND_API_KEY, so it never ends up in your code:

   Shell

   # macOS or Linux: paste the key when asked. It is not shown or saved in your history.
   read -rs UND_API_KEY && export UND_API_KEY

3. Make a request. Check who the key belongs to:

curl "https://urnextdoor.com/api/v1/me" \
  -H "Authorization: Bearer $UND_API_KEY"

const res = await fetch("https://urnextdoor.com/api/v1/me", {
  headers: {
    Authorization: `Bearer ${process.env.UND_API_KEY}`,
  },
});
console.log(res.status, await res.json());

import os

import requests

api_key = os.environ["UND_API_KEY"]

response = requests.get(
    "https://urnextdoor.com/api/v1/me",
    headers={
        "Authorization": f"Bearer {api_key}",
    },
    timeout=30,
)
print(response.status_code, response.json())

<?php
$apiKey = getenv('UND_API_KEY');

$ch = curl_init('https://urnextdoor.com/api/v1/me');
curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => [
        'Authorization: Bearer ' . $apiKey,
    ],
]);
$body = curl_exec($ch);
$status = curl_getinfo($ch, CURLINFO_RESPONSE_CODE);

echo $status, PHP_EOL, $body, PHP_EOL;

Sample response: 200 OK

{
  "ok": true,
  "user": {
    "id": 7,
    "username": "aarav",
    "display_name": "Aarav",
    "plan": "free",
    "profile_url": "https://urnextdoor.com/users/aarav"
  },
  "key": {
    "id": 3,
    "name": "Claude Code",
    "prefix": "und_sk_7Hq2x",
    "scopes": [
      "content",
      "media",
      "schedule",
      "read"
    ],
    "created_at": "2026-10-15T09:00:00Z",
    "expires_at": "2027-01-13T09:00:00Z"
  },
  "request_id": "9f8e7d6c5b4a3921"
}
