API keys for developers

A personal API key lets an AI tool, an automation or a script act for you on Ur Next Door: create and schedule posts and other content, read the site, edit your own items, and, if you allow it, comment, follow, connect and message.

Every action follows the same rules as on the website and is credited to you.

Any signed-in member can create one, on any plan including the free one. The free plan has lower daily limits than paid plans.

Go to API keys in Settings and press "Create API key". Give it a name, tick what it may do, choose when it expires, and press "Create key".

Copy the key straight away and paste it into your tool. You also get an email whenever a key is created on your account.

No. A key is shown only once, when you create it, and Ur Next Door keeps only a one-way fingerprint of it. Revoke the lost key in API keys and create a new one.

Up to 5 active keys at a time. Revoked and expired keys do not count; revoke one you no longer use to create another.

You choose when you create it: 30 days, 90 days (the default), 365 days, or never.

It stops working at once, and calls with it are refused as an invalid key. It stays in your list in API keys, marked Expired. Create a new key to carry on.

Keys also stop working while an account is suspended.

There are twelve: Create content, Upload images, Manage scheduled, Edit your content, Read lookups, Read the site, Comment and react, Follow and connect, Notifications, Profile and settings, Messages, and Marketplace and jobs.

You tick them when you create the key, and the key can do only what you ticked.

Comment and react, Follow and connect, Notifications, Profile and settings, Messages, and Marketplace and jobs start unticked because they act toward other members or your account. Tick them only if your tool needs them.

No. A key keeps the permissions it was made with. Create a new key with the permissions you need, then revoke the old one.

Keys made before 16 October 2026 have only the four original permissions, so make a new key for the newer ones.

Open API keys, find the key and press Revoke. It stops working on the next call.

Resetting your password also revokes all your keys at once.

Create and schedule posts, questions, polls, MCQs, communities, services and jobs; read feeds, search, profiles, communities, services and jobs; edit, archive and unarchive your own items; comment, answer, react, save and vote; follow and connect; read notifications; update your profile and CV; and book services and apply to jobs. While chat is switched on, it can also message your connections.

Each needs the matching permission on the key.

A key can never delete anything (it can only cancel a scheduled item), sign in or out, change your password or email, delete your account, or manage API keys. It also cannot take payments or mark a booking paid, change community roles, remove members or connections, or use the admin panel.

No. The API never deletes anything. It can cancel a scheduled item, or archive your own item so it leaves public listings; deleting stays on the website.

Content sent through the API carries no links, for anyone. Each link is taken out, its words are kept, and the post still goes through with a warning telling the tool what was removed.

No. Through a key you can edit only your own items, even if you are a moderator; the call is refused as not your content. Moderators keep their powers on the website. A community admin can still edit the community's settings through a key.

No. Messages need the Messages permission and work only while chat is switched on. A new direct chat, or a new group member, must be one of your accepted connections.

Each action, such as posts, comments or follows, has its own daily limit for all your keys together, and it resets at midnight UTC (5:30 am in India). A call that fails does not count. Reading and most status changes have no daily limit.

API keys shows today's usage against each limit.

Yes. You can make up to 60 calls a minute across all your keys, and actions that reach other members, such as comments, follows and messages, have tighter per-minute limits.

"missing_api_key" means the call was sent without a key: send it as "Authorization: Bearer und_sk_..." or in an "X-API-Key" header. "invalid_api_key" means the key is mistyped, revoked or expired, or the account is not active.

Your key does not have the permission that action needs, for example Comment and react for posting a comment. Create a new key with that permission ticked.

You called the API on a community's own address. Always call it on https://urnextdoor.com, not on a community subdomain.

"quota_exceeded" means you used today's limit for that action; it resets at midnight UTC. "rate_limited" means too many calls in a minute, or too many wrong keys sent from one address. Both answers say how long to wait.

API keys shows today's usage for each action and when it resets, plus your latest API calls with their result.

Yes. Analytics in Settings shows everything you did, split by website, app and API, with a breakdown by API key, the full event log and a CSV download.

The log of calls made with your keys is kept for 30 days, and your activity record for about 13 months (400 days). A revoked key stays listed for 90 days. All of these are deleted with your account.

No. It keeps only a one-way fingerprint of the key, plus its first and last characters so you can recognise it in the list.

Claude Code, Codex, a ChatGPT custom GPT, Postman, n8n, Zapier or any script. A ChatGPT GPT can hold only 30 actions, so ChatGPT gets two ready-made sets, Create and Social, one GPT each.

Not yet. They need a connector that is not available yet. Claude Code, Codex, ChatGPT custom GPTs, Postman and scripts work today.

Step-by-step guides, a prompt for AI agents and the full API description are at docs.urnextdoor.com. API keys links to the guides for Claude Code, ChatGPT, Codex and Postman.

Send it in a header on every call: "Authorization: Bearer und_sk_..." or "X-API-Key: und_sk_...". Never put it in the address, and keep it in an environment variable, not in a web page or a shared chat.

Yes. Posts, questions, polls, MCQs, services and jobs can be created for a later time, and a community can be scheduled too. You can list, reschedule, publish early or cancel scheduled items, and they also show on your Scheduled page.

Yes, for likes, follows and saves: repeating one answers "nothing changed" and sends no second notification. For creates, send an Idempotency-Key header, and a repeat within 24 hours returns the first result instead of creating it twice.

The Ur Next Door team can give a chosen member unlimited API use from the admin panel; members cannot ask for it in the product. It removes the daily limits but keeps a ceiling of 600 calls a minute, and does not change your plan or permissions.

No. Bodies must be HTML; Markdown is not accepted.

No. The limit of 20 posts, questions, polls and MCQs a day, together, on the website and the app does not apply to keys; keys have their own daily limits instead. The duplicate-title rule does apply: a key cannot post a title you already used on the same kind of item (post, question, poll or MCQ) in the last 30 days.

No. The AI writing assistant is not part of the API. Your own AI tool writes the text and sends it through your key.
