2 endpoints
Endpoints
Each endpoint links to its request parameters, response schema, and code examples.
- List category productsReturns one page of a software category — product name, slug, aggregate rating, review count, price band, and the traits reviewers praise and complain about. Requires slug. Each row's slug feeds /v1/g2/reviews. Fifteen products a page, with no stated total.
/v1/g2/category1 crGET - List product reviewsReturns one page of a product's reviews — title, rating, dates, the reviewer's role and company size, and the three answers G2 collects, both merged and split apart. Requires slug. Ten a page; walk with has_more and deduplicate on review id.
/v1/g2/reviews1 crGET
