Tolgee Translations API

openapi: 3.0.1
info:
  title: Tolgee API
  description: >-
    Subset of the Tolgee localization platform REST API covering projects, keys,
    translations, languages, import/export, and screenshots. Tolgee is open
    source and can be self-hosted; this specification targets Tolgee Cloud at
    https://app.tolgee.io. Project-scoped resources are authenticated with a
    Project API key (prefixed `tgpak_`) sent in the `X-API-Key` header. A
    Project API key is bound to a single project, so endpoints that implicitly
    operate on "the current project" (such as export) are accessible when
    authenticated with that key.
