Back Market

Back Market is a French-founded global online marketplace dedicated exclusively to refurbished consumer electronics — smartphones, laptops, tablets, consoles, watches, audio and home appliances — operating across 17 countries on three regional platforms (EU via backmarket.fr, North America via backmarket.com, Asia-Pacific via backmarket.co.jp). For the ~1,800 professional refurbishers selling on the platform, Back Market publishes a seller-facing REST API (the "Back Market API Guidelines") covering the marketplace taxonomy, product and listing management, order and orderline workflows, BuyBack (trade-in) orders and listings, Backship deliveries and returns, the Care after-sales platform (claims, messages, refunds, item transfers), and Backbox competitive pricing data. The API is documented as an OpenAPI 3.0.3 contract rendered with Stoplight Elements at api.backmarket.dev, authenticated with a Basic token issued from the seller Back Office, and mirrored by preprod environments on every regional platform.

Back Market publishes 9 APIs on the APIs.io network, including Backbox API, Backship API, Buy Back API, and 6 more. Tagged areas include Company, E-Commerce, Marketplace, Retail, and Refurbished Electronics.

The Back Market catalog on APIs.io includes 1 Spectral governance ruleset.

Back Market’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 28 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/back-market: open an issue to ask a question, or submit a pull request to add artifacts.
