Cronofy

Cronofy - one API for all the calendars (Google, iCloud, Exchange, Office 365, Outlook.com)

Sample Application

To see this API wrapper in action see our sample app here

Usage

Note: if upgrading from a v0.x.x version to v1.0.0, please read the migration guide

In order to use the Cronofy API you will need to create a developer account.

From there you can use your Calendar Sandbox to access your own calendars, or you can create an OAuth application to obtain an OAuth client_id and client_secret to be able to use the full API.

Authorization

API documentation

Generate a link for a user to grant access to their calendars:

$redirect_uri = "http://yoursite.dev/oauth2/callback";

$cronofy = new Cronofy\Cronofy(["client_id" => "CRONOFY_CLIENT_ID"]);
$params = [
  'redirect_uri' => $redirect_uri,
  'scope' => ['read_account','list_calendars','read_events','create_event','delete_event']
];
$auth = $cronofy->getAuthorizationURL($params);

The redirect URI is a page on your website that will handle the OAuth 2.0 callback and receive a code parameter. You can then use that code to retrieve an OAuth token granting access to the user's Cronofy account:

$cronofy = new Cronofy\Cronofy([
  "client_id" => "CRONOFY_CLIENT_ID",
  "client_secret" => "CRONOFY_CLIENT_SECRET"
]);

$params = [
  'redirect_uri' => $redirect_uri,
  'code' => $code
];

$result = $cronofy->requestToken($params);

// Retrieve credentials value
$accessToken = $cronofy->accessToken;
$refreshToken = $cronofy->refreshToken;
$expiresIn = $cronofy->expiresIn;

You should save the response's AccessToken and RefreshToken for later use.

Note that the exact same redirect URI must be passed to both methods for access to be granted.

$result will be true for a successful request; otherwise, it will be an error code. Please reference our documentation for possible error code.

Refresh Access Token

Refresh an access token for an account:

$cronofy = new Cronofy\Cronofy([
  "client_id" => "CRONOFY_CLIENT_ID",
  "client_secret" => "CRONOFY_CLIENT_SECRET",
  "grant_type" => "refresh_token",
  "refresh_token" => "YOUR_REFRESH_TOKEN"
]);

$new_access_token = $cronofy->refreshToken();

List calendars

$cronofy = new Cronofy\Cronofy([
  "client_id" => "CRONOFY_CLIENT_ID",
  "client_secret" => "CRONOFY_CLIENT_SECRET",

  "refresh_token" => "RefreshToken"
]);

$calendar = $cronofy->listCalendars();

Read events

API documentation

Get a list of all the user's events:

$cronofy = new Cronofy\Cronofy([
  "client_id" => "CRONOFY_CLIENT_ID",
  "client_secret" => "CRONOFY_CLIENT_SECRET",

foreach($events->each() as $event){
  // process event
}

Create or update events

Migration guides

• v0.X.X -> v1.0.0: version 1.0.0 adds namespacing and standardizes the names of public methods to camelCase (whereas previously some methods were named with camel_case). Where in v0.29.0 you would have written $cronofy = new Cronofy(); and $calendar = $cronofy->list_calendars();, for v1.0.0 you should write $cronofy = new Cronofy\Cronofy(); and $calendar = $cronofy->listCalendars();.
