PowerReviews

PowerReviews provides ratings and reviews software and APIs for collecting, syndicating, and displaying user-generated reviews, questions, and answers so shoppers can make better purchase decisions and retailers and brands can drive e-commerce conversion. The platform publishes two public HTTP API surfaces: a Read API (readservices-b2c.powerreviews.com) that returns reviews, questions, answers, product snippets, and merchant display configuration for a merchant and locale, and a Write API (writeservices.powerreviews.com) that retrieves the write-a-review template and submits reviews, questions, answers, and merchant responses server-to-server. Both are authenticated with a merchant-scoped apikey query parameter issued by PowerReviews support, and are documented in a MadCap Flare developer portal with Swagger 2.0 references. PowerReviews was acquired by Syndigo and now sits inside the Syndigo Product Experience Cloud.

PowerReviews publishes 8 APIs on the APIs.io network, including B2B Answer API, B2B MerchantResponse API, B2B Question API, and 5 more. Tagged areas include E-Commerce, Ratings and Reviews, User Generated Content, Retail, and Marketing.

PowerReviews’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 29 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/powerreviews: open an issue to ask a question, or submit a pull request to add artifacts.
