API Docs


The Calendsa API is a RESTful API that gives full control over the platform by exposing all resources as simple HTTP endpoints.

The Calendsa API is organized using REST principles, with resource-oriented URLs, JSON-encoded request and response bodies, and standard HTTP response codes, authentication, and verbs.

API Server Specifications

The API supports HTTP versions 1, 1.1, and 2, although HTTP/2 is preferred.

TLS versions 1.2 and 1.3 are supported, with resumption.

All requests must be encoded as JSON with the Content-Type: application/json header. If not otherwise specified, responses from the Calendsa API, including errors, are encoded exclusively as JSON as well.
