Rakuten
Rakuten Group is a Japan-headquartered internet conglomerate spanning e-commerce (Rakuten Ichiba), fintech (Rakuten Bank, Rakuten Card, Rakuten Securities), digital content (Rakuten Books, Kobo, Viki), travel (Rakuten Travel), telecom (Rakuten Mobile, Rakuten Symphony), and advertising (Rakuten Advertising). Rakuten exposes a long-standing public developer platform — Rakuten Web Services (webservice.rakuten.co.jp) — that offers REST/JSON APIs for searching Ichiba items and genres, books, CDs, DVDs, games, software, magazines, Kobo eBooks, Rakuten Travel hotels (simple, detail, vacant, keyword), Rakuten Recipe, and Rakuten GORA golf courses. All RWS APIs use a Rakuten application ID for authentication and are read-only. Rakuten separately operates merchant-facing RMS (Rakuten Merchant Server) APIs and Rakuten Pay merchant APIs, which are partner-gated.
