Multiple Recipients ALPHA

Required plan: Starter

Allows the creation of Smart Invites with multiple recipients.

As the behavior is very similar to the single recipient functionality it is recommended that you familiarize yourself with the exisiting Smart Invites documentation first.

The key difference is that rather than having a single recipient element or recipient_email parameter, there is instead a recipients collection.

Example callback #

Once a Smart Invite has been created for multiple recipients you will be able to receive notifications relating to it. These notifications will be sent as HTTP POST requests to the callback_url specified when the Smart Invite was created.

POST {CALLBACK_URL_PATH} HTTP/1.1
Host: {CALLBACK_URL_HOST}
Content-Type: application/json; charset=utf-8
Cronofy-HMAC-SHA256: {Base64(HmacSHA256(body_bytes, CLIENT_SECRET))}

{
  "notification": {
    "type": "smart_invite",
  },
  "smart_invite": {
    "smart_invite_id": "example_id",
    "callback_url": "http://www.example.com",
    "recipients": [
      {
        "email": "example@example.com",
        "status": "tentative",
        "comment": "example comment",
        "proposal": {
          "start": {
            "time": "2014-09-13T23:00:00+02:00",
            "tzid": "Europe/Paris"
          },
          "end": {
            "time": "2014-09-13T23:00:00+02:00",
            "tzid": "Europe/Paris"
          }
        }
      },
      {
        "email": "cronofy@example.org",
        "status": "pending"
      }
    ],
    "reply": {
      "email": "example@example.com",
      "status": "tentative",
      "comment": "example comment",
      "proposal": {
        "start": {
          "time": "2014-09-13T23:00:00+02:00",
          "tzid": "Europe/Paris"
        },
        "end": {
          "time": "2014-09-13T23:00:00+02:00",
          "tzid": "Europe/Paris"
        }
      }
    }
  }
}

The key difference is that rather than having a single recipient element in the response, there is instead a recipients collection. The reply still relates to the specific response that triggered the notification.

Please note that for other recipients to receive the updated status of the replying participant, they must be sent a new ICS file for the event. This can be retrieved from the Invite Status endpoint.

The difference to the request is that no recipient_email should be provided.

For the response, the difference is that rather than having a single recipient element and a replies collection in the response, there is instead a recipients collection.
