    Outreach ships exactly one current first-party client library, and it is not a REST API SDK — it is the
    browser-side Client Extensibility SDK that a web-widget extension uses to talk to the Outreach host
    application. There is no first-party server SDK for the REST API in any language: npm, PyPI, RubyGems,
    Packagist, crates.io, NuGet and Maven Central were all checked and carry no Outreach-published client.
    Integrators are expected to call the JSON:API surface directly, or use the MCP server.
registries_checked:
- registry: npm
  result: no first-party package. `@getoutreach/extensibility-sdk` is NOT published to npm (404 on
    registry.npmjs.org); the package named `outreach` is an unrelated 2019 message-queue library.
- registry: rubygems
  result: one community gem (omniauth-outreach)

  published_note: >-
    No registry metadata endpoint exists for this package — it is installed straight from GitHub, is not
    published to npm, and the repository carries ZERO git tags and ZERO GitHub releases. The version above
    was read from package.json on the default branch; its last commit touching package.json was
    2026-07-02, and the repository was last pushed 2026-08-10, so the code is actively maintained even
    though nothing is released. A consumer running `npm install github:getoutreach/extensibility-sdk` gets
    whatever is on the default branch at that moment — the distribution is unpinned and unversioned in
    practice.
  scope: Client extensibility only — initialises a web-widget/tab/tile/shell extension inside the Outreach
    app and returns the OutreachContext. It is not a REST API client.

    repository of the same name exists in the getoutreach GitHub org but the gem is not published by
    Outreach and declares no first-party ownership.

gaps:
- No first-party REST API client library in any language, for an API that has been at v2 for the life of the
  developer portal.
- The one current first-party package is distributed only as a GitHub dependency with no tags, no releases
  and no registry presence, so consumers cannot pin a version or receive a security advisory through any
  package ecosystem.
