A Time slot is a session type where the attendee reserves a specific time from a list. The session has a defined duration (for example, one hour), which the system splits into individual slots (for example, 15-minute slots with a 5-minute break between them). The attendee picks the slot that fits their schedule. Typical use cases: test drives, one-on-one consultations, one-to-one meetings, social program (detail in Setting up reservations in the Agenda — buses, workshops, social program).
Decide the length of one slot (5, 15, 30, 60 minutes) based on how much time you need for the interaction.
Decide the break length between slots (a pause for handover or reset). The default is 5 minutes.
The maximum number of attendees per slot is usually 1 (one-on-one consultation), but you can allow more (group slots).
A Time slot is a session, so it has a stage, speakers (instructors / experts), and the other attributes of a regular session.
A session of type Time slot has, in addition to the usual tabs, an extra Slots tab in the edit panel. To create one:
Create a session of type Time slot (or a custom type built on this base).
Enter date, start, end — this defines the total session length (for example, 9:00–12:00 = 180 minutes).
In the Registration settings section, enter:
Time slot length — for example, 15 minutes. The default in the dropdown is 15 min.
Break length — pause between slots (default 5 min).
Limit total registrations — number of attendees per slot (default 1).
Save. The system generates the slots.
For a 180-minute session with 15-minute slots and a 5-minute break, the system generates 9 slots (9:00, 9:20, 9:40, 10:00, 10:20, 10:40, 11:00, 11:20, 11:40).
The Slots tab is available only for sessions of type Time slot. It shows every generated slot — each with its time range, capacity, and number of registered attendees. Breaks between slots are shown as separate rows.
For each slot you can:
Toggle Active / Inactive — an inactive slot is not available for registration (typically when an instructor drops out and the slot is canceled).
Click the Attendees button to open the Edit attendees dialog — you see the list of registered attendees, the limit, and the capacity. The organizer can:
Remove an attendee from the slot.
Add an attendee manually (search in the field and add). Manually assigned attendees are marked as Assigned by organizer.
The attendee opens the session in the attendee app.
They see the list of available slots with occupancy (if showing remaining spots is turned on).
They tap a specific slot, which registers them.
The slot shows up in My Agenda.
If deregistration is allowed, they can release the slot until the configured deadline.
A Time slot has the same set of registration settings as a Workshop:
Assign attendee to a group after registration
Registration only for selected groups
Limit registrations (per single slot, not per session as a whole)
Show the number of available spots
Session deregistration
Notify the organizer / attendee
Send ICS to attendee
For details, see Setting up workshops and session registration.
The default value of Limit total registrations for a Time slot is 1 (one-on-one meeting). You can raise it — for example, to 3 per slot for a group consultation. Everyone registered for one slot arrives at the same time.
When an attendee cancels their registration:
The slot is freed.
The spot becomes available for another attendee.
Happenee does not have an automatic waitlist — the spot is not reassigned automatically.
You can have several sessions of type Time slot in the Agenda at the same time (for example, Consultation with the CFO and Consultation with the CTO). Each session has its own slots. An attendee can register for slots across sessions, unless concurrent-registration restrictions are turned on (see Building the event Agenda — architecture).
After the first attendee registers for a Time slot session, you cannot change:
The session type
Start and end time
Time slot length
Break length
Plan these parameters in advance. You can add more time (for example, 12:00–14:00 as a second session), but you cannot edit existing sessions after a registration.
A speaker is assigned to the session as a whole, not to a specific slot. Attendees in every slot see the same speaker / instructor. If you need to split slots between several speakers, create several sessions (one per speaker).
The real slot length has to match the real interaction. A one-on-one consultation usually needs 15–30 minutes plus a short pause.
The slot start and end time are locked after the first registration. Plan the final schedule before opening registration. If you have to change it, deregister everyone manually first, then edit, then open again.
Check that Time slot length and Break length are set. Without them, slots are not generated. The Slots tab shows what the system has generated.
Raise Limit total registrations to 3. Note: everyone who registers arrives at the same time at the same slot. If you need more groups, create more sessions or split the time differently.
Happenee does not have a waitlist today. The freed spot is available to everyone — the first person to click Register gets it.
After a slot is reactivated, the attendee is not added back automatically. You have to look them up and add them manually through the Edit attendees dialog.
