Event Registration Creation with API - Custom Registration Fields

(0) ShareShare
ReportReport
Posted on by 10

Are we still unable to set Custom Registration Fields though the Event Management API? I have a custom web app retrieving and registering attendees. I want to include one of our Custom Event Registration fields when I register the attendee for the event. Is there any way to do that through the API?

IE:EvtMgmt/api/v2.0/events/readableEventId/registrations?
{
 "attendees": [
 {
 "firstName": "Test",
 "lastName": "Tester",
 "email": "test2@email.com",
 "customfields":[{"fieldname":"12345"}]
 }],
"hipObject": null
}

    Hi Tim,

    We can open console > Network > XHR to check the request payload for event registration.

    If we copy the json and format it with online formatter, then we will find it uses responses property to save custom registration fields value, and the id is guid of the corresponding custom registration field record.

    {
      "attendees": [
        {
          "firstName": "0101",
          "lastName": "1101",
          "jobTitle": "No",
          "email": "hello123@outlookc.om",
          "passId": "",
          "waitlisted": false,
          "autoRegister": false,
          "responses": [
            {
              "id": "a8dbfc7f-7c08-eb11-a813-000d3aa08990",
              "value": "Yes"
            },
            {
              "id": "655c848f-7c08-eb11-a813-000d3aa08990",
              "value": "15611112223"
            }
          ],
          "attendeeSessions": [
            {
              "sessionId": "9a83b99e-2af3-ea11-a815-000d3aa08990",
              "waitlisted": false
            }
          ]
        }
      ],
      "hipObject": null
    }
