Friendbuy

Friendbuy is a referral and loyalty marketing platform for ecommerce and direct-to-consumer brands. Merchants launch referral, loyalty, and reward campaigns through on-site widgets and a no-code dashboard, and integrate server-to-server through the Friendbuy Merchant API (base https://mapi.fbot.me/v1). The Merchant API lets merchants sync customer records, generate personal referral links, track purchase / sign-up / custom conversion events, pull campaign and reward analytics, and manage loyalty ledger balances, adjustments, redemptions, and coupons. Authentication is a key/secret exchange at POST /authorization that returns a short-lived Bearer JWT. Access to the API and to production credentials is gated behind a paid, contact-sales plan.

Friendbuy publishes 7 APIs on the APIs.io network, including Analytics API, Authorization API, Customers API, and 4 more. Tagged areas include Referral Marketing, Loyalty, Rewards, E-Commerce, and Marketing.

The Friendbuy catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Friendbuy’s developer surface includes authentication, documentation, engineering blog, changelog, API reference, getting-started guide, support, and 24 more developer resources.

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.

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/friendbuy: open an issue to ask a question, or submit a pull request to add artifacts.
