  title: Caspio REST Applications Authentication API
  description: 'The Caspio Bridge REST API (v3) provides programmatic access to tables, views,

    records, files, users, applications, and tasks in a Caspio account. The base URL

    is account-specific (per-tenant integration URL) and authentication uses an OAuth

    2.0 client credentials flow to obtain a bearer access token. This best-effort

    OpenAPI is derived from the public help documentation at

    https://howto.caspio.com/web-services-api/rest-api/ and the demo Swagger at

    https://demo.caspio.com/integrations/rest/swagger.
