Feefo Email marketing # Connect Feefo to Hypamoon Yes, with one catch. Feefo has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today. Open ## The check Three questions about the API of Feefo, answered from its own docs. **Public API docs**\ **Yes.** Public developer section with the Reviews API, Product Ratings API and download API. [Read the docs](https://help.feefo.com/knowledge-base/for-developers) **A key you create yourself**\ **Yes.** You create an App Key under Settings, Connectivity, App Keys in the Feefo Hub and read the client ID and secret there. [help.feefo.com](https://help.feefo.com/knowledge-base/how-to-connect-using-an-oauth-2.0-token) **Versions or a changelog**\ **Yes.** Numbered API versions (10 and 20) with release dates. [help.feefo.com](https://help.feefo.com/knowledge-base/api-versions) **How it signs in**\ OAuth 2.0 token from the client ID and secret of an App Key; public review reads need no authentication. **Webhooks**\ **Yes.** It can tell your app when something changes. [help.feefo.com](https://help.feefo.com/knowledge-base/webhooks-overview) **Hosting**\ Cloud ## What you can build Show your Feefo reviews on your own pages and follow up on new or negative reviews automatically. Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### Good to know - Feefo signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Feefo takes more work: ask your chat to check this first. - Public reviews and ratings can be read without a key; NPS and other private data need the OAuth token. ## Try it in your chat Fill in what to read and write, and send it.

Ask the chat to check its API. The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
