Microsoft LinkedIn

LinkedIn, owned by Microsoft, operates a versioned Rest.li API platform covering advertising and marketing, company page and community management, talent and recruiting, sales navigation, learning, and consumer sign-in. The versioned Marketing surface lives under https://api.linkedin.com/rest/ and requires a Linkedin-Version YYYYMM header on every call, with each monthly version supported for a minimum of twelve months before it is sunset. Authentication is OAuth 2.0, and Sign In with LinkedIn is a conformant OpenID Connect provider with a live discovery document. Access to the Marketing, Talent, Sales and Learning APIs is gated behind product approval and, in most cases, a commercial partner relationship; LinkedIn publishes no API pricing and no OpenAPI definitions of its own.

Microsoft LinkedIn publishes 5 APIs on the APIs.io network, including AdAccounts API, AdAccountUsers API, AdCampaignGroups API, and 2 more. Tagged areas include Marketing, Microsoft, Professional Networking, Recruiting, and Social Network.

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

Microsoft LinkedIn’s developer surface includes authentication, developer portal, documentation, support, API reference, getting-started guide, signup flow, and 38 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/microsoft-linkedin: open an issue to ask a question, or submit a pull request to add artifacts.
