Open VSX reviews API

Read and reply to Open VSX reviews with the same API you use for every other platform. Every review of the extension, with stars, text, reviewer and date.

Read only Beta

Open VSX reviews can be read through Prisma’s REST API: one API key, the same JSON fields as every other platform (rating, text, author, date, reply, url) and a webhook for each new review. Open VSX doesn’t let third parties reply by API, so each review carries a link to answer it on the platform.
