Match Webhook Events to Automatic Registrants

API and Webhooks

Description
We want to create a meeting and some registrants via the API. Then we want to know when registrants join and leave.

Which Endpoint/s?

How To Reproduce

NOTE: Unimportant fields are removed for brevity and privacy. I can add any important ones I may have left out.

Create a meeting:

{
  "uuid": "6cZgo3elR1yheYO7+wix4Q==",
  "id": 95974452713,
  "host_id": "wW9d2YoQSPuEZwoPysLu0Q",
  "topic": "6543211",
  "type": 2,
  "status": "waiting",
  "start_time": "2020-10-22T20:51:52Z",
  "duration": 60,
  "timezone": "America/Chicago",
  "created_at": "2020-10-22T20:51:51Z",
  "settings": {
      "approval_type": 0,
      "enforce_login": false,
      "enforce_login_domains": "",
      "alternative_hosts": "",
      "close_registration": false,
      "show_share_button": true,
      "allow_multiple_devices": true,
      "registrants_confirmation_email": true,
      "registrants_email_notification": true,
      "meeting_authentication": false
  }
}

Then create some registrants:

GET /meetings/{meeting_id}/registrants
{
  "page_size": 30,
  "total_records": 3,
  "next_page_token": "",
  "registrants": [
      {
        "id": "dl_bhAjHTy2erZcMVTs_RQ",
        "first_name": "Client",
        "email": "333@calls.glgroup.com",
        "status": "approved",
        "create_time": "2020-10-22T20:52:41Z"
      },
      {
        "id": "NNshzJ5dT52GznTWA7at_w",
        "first_name": "Client",
        "email": "222@calls.glgroup.com",
        "status": "approved",
        "create_time": "2020-10-22T20:52:33Z"
      },
      {
        "id": "O6LGl9ULSha5eAiCl8Q_OA",
        "first_name": "Client",
        "email": "111@calls.glgroup.com",
        "status": "approved",
        "create_time": "2020-10-22T20:52:25Z"
      }
  ]
}

The look at incoming webhook payload for participant joined:

{
  "payload": {
    "account_id": "vruVXrjZRXG0rgzqRtYSRw",
    "object": {
      "uuid": "/JAZ67I/RmC3ugRXKr6Y8g==",
      "participant": {
        "user_id": "16782336",
        "user_name": "Client",
        "id": "_DFgu8W9TB6X-72za6Qwqg",
        "join_time": "2020-10-22T20:57:09Z"
      },
      "id": "95974452713",
      "type": 2,
      "topic": "6543211",
      "host_id": "wW9d2YoQSPuEZwoPysLu0Q",
      "duration": 60,
      "start_time": "2020-10-22T20:54:26Z",
      "timezone": "America/Chicago"
    }
  },
  "event": "meeting.participant_joined"
}

There seems to be no data in the webhook event that would allow me to tie it back to registrant. What am I missing?

Hi @timscott,

Thanks for reaching out about this and for laying out the steps you’re taking. At the moment, you’re correct in that there is not a straight forward way to map these two IDs together. However, our team plans to release a mappable ID very soon to address this. In the meantime, please see this thread which offers some more context and suggestion for the meantime:

Thanks,
Will
