  title: Planning Center Calendar API
  description: 'A representative OpenAPI description of the Planning Center suite of church management APIs. Planning Center exposes a documented public REST API for each of its products - People, Services, Giving, Groups, Check-Ins, Calendar, Registrations, Publishing - plus a cross-product Webhooks API, all under the shared base host https://api.planningcenteronline.com. Every product is versioned under its own path prefix (for example /people/v2, /services/v2, /giving/v2). All responses conform to the JSON:API 1.0 specification: resource objects are wrapped in a top-level `data` member (an object or an array), each with `id`, `type`, `attributes`, and `relationships`, and collections support `include`, `where[]` filtering, `order`, and offset-based pagination via `per_page` and `offset`. Authenticate with HTTP Basic using a Personal Access Token (application id / secret) or with an OAuth 2.0 bearer token. A `User-Agent` header is required on every request.

    Endpoint coverage: the resource collections and base paths modeled here are grounded in Planning Center''s published documentation. Individual method/path combinations are a representative CRUD-shaped subset; consult the live API reference at developer.planning.center for the authoritative, exhaustive list and per-resource attributes.'
