Parameters:
  • (string) $schema_profile Optional. Name of the schema profile to get keywords for. Accepts 'rest-api' or 'draft-04'. Any other value falls back to the 'rest-api' profile. Default 'rest-api'.
    Required: No
    Default: 'rest-api'
Returns:
  • (string[]) Allowed JSON Schema keywords.
Defined at:
Codex:

Gets the JSON Schema keywords allowed for a given schema profile.

Use this when preparing a schema that will be consumed outside of WordPress's server-side validation, such as by REST clients, frontend code, or AI providers. The 'rest-api' profile returns the subset of JSON Schema draft-04 keywords that the REST API has historically exposed. The 'draft-04' profile preserves the larger draft-04 vocabulary used by clients that can consume standalone schemas. Allowing a keyword to be exposed does not make WordPress validate or sanitize values against it.
