openapi: 3.1.0 info: title: 'Drupal JSON: Comments Users API' description: The Drupal JSON:API module is a core component that exposes all Drupal entity types and bundles as a standards-compliant JSON:API interface, requiring no configuration to enable. Each entity bundle receives a unique URL path following the pattern /jsonapi/{entity_type}/{bundle}, and the module supports GET, POST, PATCH, and DELETE operations for full CRUD access. It supports filtering, sorting, pagination, sparse fieldsets, includes for relationship resolution, translations, revisions, and file uploads out of the box. All resource identifiers use entity UUIDs rather than numeric IDs. The JSON:API module is the recommended approach for most decoupled and headless Drupal applications due to its adherence to the open JSON:API specification (jsonapi.org) and its compatibility with the broader JSON:API client ecosystem. version: '1.1' contact: name: Drupal Community url: https://www.drupal.org/community termsOfService: https://www.drupal.org/about/legal servers: - url: https://example.com/jsonapi description: Drupal JSON:API Base (replace with your Drupal installation base URL) security: - basicAuth: [] - oAuth2: - content tags: - name: Users description: JSON:API endpoints for Drupal user entities.
