“Nextdoor API” is one of those searches where the useful answer is a negative one, followed by what to do instead. This is that answer.
The short answer
There is no public Nextdoor API for reading business listings, neighbor recommendations or city data. Nextdoor has developer-facing surfaces, but they exist so that advertisers can buy advertising and so that businesses can manage their own profile — they authenticate as that business and they are not a read interface over the platform's content.
If you need Nextdoor data as structured rows, you are choosing between reading its public pages and not having the data.
What Nextdoor's interfaces actually cover
Broadly three things, none of which is a data feed: campaign management for advertisers, profile and post management for a business that owns a page, and partner integrations negotiated case by case. All three are scoped to an authenticated account acting on its own behalf.
That is the normal shape for a consumer social platform. The interfaces exist to let money and content flow in, not to let content flow out.
Why there is no public data API
The content is the product, and much of it is written by residents about their neighbourhood. A read API over that would be a bulk export of personal content with a rate limit attached, which is a liability rather than a feature. The absence is a policy choice, not an oversight, and it is not going to be reversed by asking.
Which is also why the boundary this project draws — business listings yes, neighbor posts off by default — tracks the same distinction Nextdoor itself is protecting.
The four options, ranked by how long they keep working
- Read the signed-out public surface. Business listings, recommendations, city data. Nothing expires, and the ceiling is whatever an anonymous visitor can see.
- Manual collection. Accurate, auditable, and it does not scale past a few dozen records.
- A cookie-based scraper. Larger coverage, borrowed credentials, and a failure date nobody chose.
- A partner arrangement. The only route to a documented contract, available to approximately nobody reading this.
For most work the first option is the whole answer, because the fields people actually want — name, phone, website, category, city, what neighbors said — are all on the public surface.
Why cookie-based scrapers break
A session cookie is a credential with an expiry. When it lapses, a scraper built on it does not degrade gracefully: it either starts returning empty results or starts returning the logged-out version of a page while your code still expects the logged-in one. The second failure is worse, because it looks like data.
There is a fuller comparison of the two approaches, including what the signed-out route genuinely gives up.
What a public-surface reader can and cannot return
| Data | Available signed out |
|---|---|
| Business name, categories, contact details, address | Yes |
| Opening hours, verification status, gallery | Yes |
| Neighbor recommendations (free text, anonymized author) | Yes |
| City demographics, scores, category coverage | Yes |
| Business-published posts | Yes |
| Star ratings | Do not exist on Nextdoor |
| Free-text business search | No — requires login |
| Private groups, member feeds, direct messages | No — requires login |
| Author identities beyond a first name and initial | No — never resolved |
How to choose
Ask what happens to your project when the data source stops responding for a week. If the answer is “a report is late”, a cookie-based tool may be an acceptable trade for broader coverage. If the answer is “a customer-facing feature breaks”, take the smaller, stable surface and design around its limits — starting with the fact that discovery runs by city and category rather than by keyword.
The Nextdoor Business & Reviews Scraper documents exactly which fields that surface yields and how often each one is populated.
