Stamped reviews API
Prisma Reviews is a reviews API that reads Stamped reviews through Stamped’s official API, with credentials the business creates in its own account, in the same JSON format as its other 83 platforms. It can’t reply to Stamped reviews by API: each review carries a url to answer it on Stamped. New reviews are checked every hour on Spark and Beam, every 15 minutes on Spectrum and Aurora. Included in the free Spark plan (2 locations, no card).
Read only Beta
The store’s product reviews with stars, title, text, the reviewer’s name, the product page and the store’s reply. One API key, the same JSON fields as every other platform (rating, text, author, date, reply, url) and a webhook for each new review.

Frequently asked questions
Can I reply to Stamped reviews through the API?
Read only: Stamped’s API has no endpoint to reply to reviews, so the store answers in Stamped. The answer comes back with the review.
How do my customers connect Stamped?
The store copies its public key, private key and store hash from Stamped → Settings → API Keys and gives them to Prisma. Stamped opens its API on its higher plans.
