Create a Slack Incoming Webhook: In Slack, go to “Apps” → “Incoming Webhooks” and create a new webhook for the desired channel. Copy the generated webhook URL.
Create a webhook in Oniva: Open the webhook settings in Oniva and add the Slack webhook URL as the endpoint. Select the events that should trigger notifications (registration or check-in).
Activate the webhook at event level: Once created, the webhook must be enabled for the relevant events.
Test: Perform a test registration and check whether the notification appears correctly in the Slack channel.

Live registration monitoring: Each new registration automatically posts the participant’s name, email and selected option in a dedicated Slack channel – ideal for real-time visibility for the event team.
On-site check-in notifications: When participants are checked in, a notification appears in the Slack channel used by the check-in team – helpful for coordination at large in-person events.
Instant alerts for VIP registrations: When a participant from a specific permission group (e.g. VIP or sponsor) registers, Slack notifies the responsible account manager immediately.
