Car dealer reviews API: Google, Yelp, Facebook, BBB and Trustpilot for dealerships and garages

Prisma is a car dealer reviews API: one REST API that reads the reviews of the car dealerships and garages you own or manage, from every platform that matters to them, in one JSON shape, with a signed webhook on every new review. Built for dealer groups, dealership CRMs and DMS vendors, and the agencies that run dealer reputation.

2 locations free. Test keys return sample reviews from every platform. No card, no sales call.

Why car dealerships and garages need an API, not six integrations

• A dealer group runs sales and service as separate Google profiles per site, so 15 dealerships can mean 30 profiles.
• Google approves API access per developer project after 60 days of verified profile; the group applies once, not per store.
• Facebook removed Page reviews from its API, BBB has none, and Yelp returns 3 excerpts, so those are read from the public pages.
• A service-department complaint needs the service manager, not the sales manager, and the review doesn’t say which.

Prisma measured all of this when it integrated the platforms; the per-platform rules are in the State of Review Platform APIs 2026.

The platforms, and what each one allows

Google Business Profile and Trustpilot will join as soon as each platform approves Prisma’s access. Until then, Prisma reads your public Google reviews from Google Maps, read only. Everywhere else the review comes with its URL and you answer on the platform.

What teams build with it

1. One review feed per dealership and department, inside the CRM or DMS, with sales and service separated by profile.
2. A webhook that routes each review under 4 stars to the right manager within the hour, with the link to answer.
3. Monthly CSI-style reports per store across Google, Yelp, Facebook and BBB from the same JSON.

One call, every platform

curl "https://api.prismareviews.com/v1/reviews?platform=google_maps&has_reply=false&since=2026-10-01" \
  -H "Authorization: Bearer $PRISMA_API_KEY"

Every review comes back with the same fields whatever the platform: id, platform, location_id, rating (always out of 5), title, text, author, language, created_at, reply and url. This call lists the Google reviews read from Google Maps since 1 October that nobody has answered yet; drop the platform filter and you get every platform in one list, newest first. Register a webhook with POST /v1/webhooks to receive review.created the moment a new one is synced; the webhooks reference has the payload and the signature check.

Honest limits

• Prisma reads reviews of businesses you own or manage. It is not a scraper for competitors’ reviews.
• On platforms without a reply API, Prisma can’t post for you; it returns the link and the existing reply.
• Public-page platforms are read on a schedule (every 6 to 24 hours depending on the plan), not in real time; see how often Prisma checks.
• Prisma never writes replies. Your team or your own AI writes them; Prisma publishes the exact text you approve.

FAQ

Can I reply to Google reviews of my dealerships by API?

Once Google approves Prisma’s Business Profile access: Google requires the profile to be verified for 60 days before the application. Until then, Google reviews are read from the Maps listing and you answer on Google; the review link is in every record.

Does Prisma cover DealerRater or Cars.com reviews?

Not today. If your group needs them, ask for them from the dashboard or the integrations page; Prisma adds platforms by request when a public page or an owner API exists.

Does Prisma write the replies?

No. Prisma never writes a reply. Your team or your own AI drafts it, a person approves it, and Prisma publishes exactly that text where the platform allows it.
