StubHub

StubHub is the world's largest secondary-market ticket marketplace, connecting buyers and sellers of tickets to sports, concerts, theater, and live events. Its official developer platform (developer.stubhub.com, migrated to a v2 API in 2022 on api.stubhub.net) exposes five partner-gated REST APIs — Account, Catalog, Inventory, Sales, and Webhooks — that let approved affiliate and seller-integration partners search events, create and manage seller listings, upload e-tickets, fulfill sales and shipments, view payments, and subscribe to event webhooks. All resources use the application/hal+json (HAL) media type and OAuth2 (client-credentials and authorization-code flows). StubHub is a viagogo company and its official GogoKit SDKs (.NET, Ruby) target the shared HAL API.

StubHub publishes 15 APIs on the APIs.io network, including Addressess API, Categories API, E-Tickets API, and 12 more. Tagged areas include Company, Marketplace, Ticketing, Event, and Live Events.

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

StubHub’s developer surface includes authentication, documentation, API reference, getting-started guide, engineering blog, support, sandbox, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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