State of Review Platform APIs 2026

What 32 review platforms let developers do by API, measured by integrating every one of them.

Prisma Reviews connects to 32 review platforms through one API. To build it we had to read every platform’s developer documentation, apply for every access programme and find out, one by one, what each one allows a third party to do with a business’s own reviews. This report is that inventory, as of October 2026. It uses only what each platform documents or answers publicly; nothing here comes from private agreements.

The headline numbers

Read the first two rows together: if you build a product that “replies to reviews”, only a quarter of the platforms your customers care about will let you, and on every one of them you need the owner’s own authorisation.

1. Replies are the exception

The 8 platforms with a reply API: Google Business Profile, App Store, Google Play, Judge.me, Trustpilot, eBay, Trusted Shops and eKomi. Even there the rules differ:

• Google caps a reply at 4,096 bytes and 10 edits per minute per profile, and replies need the business.manage OAuth scope.
• Judge.me can create a reply but never edit or delete it by API.
• Apple and Google Play allow create, update and delete, with an App Store Connect key (Customer Support role) or a Play Console service account.
• Trustpilot’s reply API comes with its API module, sold to the business, not to the integrator.

The other 24 platforms, including Yelp, Tripadvisor, Booking.com, G2, Capterra and every marketplace, expect the owner to answer in their own dashboard. The practical design for a multi-platform product is the one we ended up with: a reply endpoint that returns 422 reply_not_supported plus a link to the review on the platform, instead of pretending.

2. Half the platforms have no API for reviews at all

16 of the 32 give a third party nothing better than the public listing page. They fall into three groups:

• Never had one: OpenTable, DoorDash, Checkatrade, Avvo, Angi, Apartments.com, Capterra, Salesforce AppExchange.
• Had one and closed it: Facebook removed the Page ratings API in Graph API v22.0; Booking.com paused new connectivity partners; Tripadvisor’s Content API returns a handful of reviews for display, not an owner feed.
• Public read endpoints that need no merchant credentials: Steam, WordPress.org and Etsy (Etsy behind an app key per integrator).

Yelp is the edge case: its Fusion API exists, but returns 3 review excerpts per business. For an owner who wants every review it is the same as having none.

For these platforms the only honest options are reading the public page of the business you own (what Prisma does, through data providers, with no login shared and a cost per read) or doing without.

3. Access is gated more by process than by code

Of the 16 platforms with a usable official API:

Google’s is the gate everyone hits. The requirements as published: a Google Cloud project, a Business Profile verified and active for 60+ days, a website, and the “Application for Basic API Access” form. Until approval the quota is 0 queries per minute; after it, 300. We are in that queue ourselves, and we document where it stands in our access guide.

The Shopify review apps are the other trend worth naming: the API is increasingly a feature of the merchant’s plan. Okendo told us in writing, when we applied as a technology partner, that its merchant API is for Growth plans and above and its webhooks for Enterprise. Loox, REVIEWS.io and ProvenExpert publish the same model. For a developer this means your integration’s availability depends on what your customer pays the platform, not on you.

4. Nobody pushes; everybody polls

Only Google offers new-review notifications to third parties, and only through its Notifications API on Cloud Pub/Sub, after the access approval. No other platform in the list pushes reviews to an integrator. The app stores have no webhooks, Google Play’s API returns only the last 7 days (older reviews come from monthly reports), and the Shopify apps that have webhooks reserve them for top plans.

So every multi-platform product is a scheduler. What we learned about running one honestly, including why polling paid sources must have a budget cap, is in Review platform APIs: lessons from integrating 25 of them.

5. Data models: five ways to say “four stars”

Across the 32 platforms we met at least five representations of a rating: integers, strings, enums (FOUR), scores out of 10 (Checkatrade) and binary recommendations (Steam, Facebook) that we map to 5 or 1. Dates come as ISO 8601, Unix seconds or platform-specific strings. Several platforms auto-translate review text and bury the original. The unified shape we settled on (rating as an integer 1 to 5 or null, original text plus language, ISO dates, reply as an object with a status) is documented in the API reference.

6. What the numbers mean for builders

• If you only need Google, apply for Business Profile API access on day one and build against fixtures while you wait. Budget for one more migration: reviews still live on the v4 API.
• If you sell to local businesses, assume read only on everything except Google, and design the “answer on the platform” link as a first-class feature.
• If you sell to e-commerce, check which plan your customers are on with each review app before promising an integration.
• If you need more than two platforms, the work is access, normalisation and polling cost, not HTTP. That is what a unified reviews API packages.

Method and scope

The 32 platforms are those Prisma supports as of 27 October 2026, chosen by demand from local businesses, apps, e-commerce, hospitality, B2B software and marketplaces. “Reply by API” means the platform’s official API lets the account owner publish a reply through a third party. “Official reviews API” means an API that returns the owner’s reviews after the owner authorises the integrator with a sign-in or a credential. Plan and approval gates are as published by each platform or stated to us in writing. We update this page when a platform changes its rules; the per-platform detail is on Which review platforms have an API?, and each platform’s page shows the exact connection request.

If a platform’s rules changed and this page is out of date, tell us at hello@prismareviews.com and we’ll correct it with credit.

FAQ

How many review platforms let you reply by API?

8 of the 32 platforms in this report let the account owner publish replies through an official API: Google Business Profile, App Store, Google Play, Judge.me, Trustpilot, eBay, Trusted Shops and eKomi. The other 24 offer no reply API to third parties.

Which review platforms have no API for reviews?

Of the 32 in this report, 16 have no reviews API open to third parties, or only a token one (Yelp’s public API returns 3 excerpts). Among them: Tripadvisor, Booking.com, OpenTable, DoorDash, Facebook (ratings API removed in Graph API v22.0), Capterra, Avvo, Checkatrade, Angi, Apartments.com and Salesforce AppExchange.

Is the Google reviews API free?

The Google Business Profile API is free but gated: a profile verified and active for 60+ days, an application reviewed by hand, and 0 queries per minute until approved (300 after). The Places API is immediate but paid per request and returns at most 5 reviews per place.
