An ICU skeleton strips the literal text from a pluralized or select message while preserving its structural rules — argument names, plural categories, select cases, and ordinal forms — adjusted to the pluralization rules of each requested locale. Use this endpoint to normalize translation templates before importing them into locale files, or to validate that a source string carries the plural forms required by a target language. Either `content` or `id` must be provided — supplying both or neither returns 400. When `id` is used and the referenced translation does not exist, the endpoint returns 404. When the source string is not valid ICU message format syntax, the endpoint returns 422 with an `error` field describing the parse failure. ## OpenAPI ````yaml /openapi/phrase-strings.json post /icu/skeleton openapi: 3.0.3 info: title: Phrase Strings API Reference version: 2.0.0 description: >- Phrase Strings is a translation management platform for software projects. You can collaborate on language file translation with your team or order translations through our platform. The API allows you to import locale files, download locale files, tag keys or interact in other ways with the localization data stored in Phrase Strings for your account. contact: name: Phrase Support url: https://developers.phrase.com/api/ email: support@phrase.com x-logo: url: https://developers.phrase.com/images/phrase-logo.svg backgroundColor: '#03eab3' altText: Phrase Strings termsOfService: https://phrase.com/terms/ license: name: MIT url: https://choosealicense.com/licenses/mit/ servers: - url: https://api.phrase.com/v2 description: EU production server - url: https://api.us.app.phrase.com/v2 description: US production server security: - Token: [] - Basic: [] tags: - name: Accounts - name: Authorizations description: > The endpoints provided by the Authorizations API are **only accessible via Basic authentication with email and password**. When creating a new authorization, the new access token for this authorization will be returned in the immediate response but not later, due to security reasons. When accessing authorizations later, you will only see the last eight chars of the token in plain text (`token_last_eight`) and the SHA256 digest of the token for reference (`hashed_token`). For instructions on how authorization in general works, see our [Auth Guide](#overview--authentication). ### Scopes When creating or updating an OAuth authorization, you can define a list of scopes to limit the access that can be performed by that authorization. #### Available Scopes
Scope Description
read Read projects, locales, keys, translations, orders
write Write projects, locales, keys, translations but not orders
orders.create Create and confirm orders
team.manage Manage invitations and members
