Webinar Registrants Download URL

Generate a download URL for a webinar's registrants as a CSV file

Generate a URL to download every registrant of a webinar event, with their live attendance, as a CSV file. Use it to import registrants into a CRM such as HubSpot or Marketo. The request takes no body.

curl -X POST \
     -H "Authorization: Bearer [access token]" \
     https://api.restream.io/v2/user/events/{eventId}/webinar/registrants/download-url

Path Parameters:

Response

The returned downloadUrl is a tokenized link that works until expiresAt, one hour after it is issued. Fetch it directly to download the CSV — no Authorization header is required on that URL, so share it only with people who may see the registrants.

CSV file

The file is UTF-8 with a byte order mark, so spreadsheet apps read non-ASCII names correctly. It has one row per registrant, including those whose access was removed:
