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, Ecommerce, and Marketing.

Friendbuy’s developer surface includes authentication, documentation, engineering blog, and 7 more developer resources.

Where this information came from

This is an independent, third-party profile of Friendbuy, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
