SCEDULY REST API Documentation

Introduction

SCEDULY REST API provides a standardized interface for interacting with the SCEDULY system. Communication is performed via the HTTPS version of the HTTP protocol using standard GET and POST methods for data transfer. Requests and responses are formatted using the JSON format.

Authentication

SCEDULY REST API uses the HMAC-SHA256 method to calculate the request signature. Each request must contain a minimum of 3 parameters required for authentication: user, institutionID, signature.

Signature calculation:

data =	HTTP_REQUEST_METHOD + CRLF
	institutionID + CRLF
	RequestURI + CRLF
	Date

signature = HMAC-SHA256(data, password)
* HTTP_REQUEST_METHOD: GET or POST
* institutionID: institution ID in the SCEDULY system
* RequestURI: requested resource (ex: "/users/tuitions")
* Date: CEST (UTC+2), in format YYYY-MM-DD HH:ii (current: 2025-07-14 23:16)
* CRLF: Carriage return (char(13)) + Line feed (char(10))

Example in PHP:

$data =	'GET' . "\r\n" .
	'999' . "\r\n" .
	'/users/tuitions' . "\r\n" .
	'2022-12-31 23:59';
$signature = hash_hmac('sha256', $data, '1234');

Limitations

1. Only 10 connections at a time are allowed. Retrieving data with more than 10 simultaneous (parallel/concurrent) connections is not permitted!
2. Synchronization frequency is maximum of once per day. Retrieving data in second/minute/hour interval is not permitted!
3. Requests with network transmission time of up to 59 seconds will be accepted 100% of the time. Requests that arrive 2 or more minutes after they are signed will not be processed.
4. Changes to the API are announced at least 30 days in advance.
* Retrieval of data contrary to 1. and 2. may lead to account suspension!
