Notifications

SMS on Cancellation Text you when SlotFill detects a cancellation

Auto-notify Top Match Automatically send SMS to the best waitlist match when a slot opens

Push Notifications Get instant browser alerts when clients claim your slots

Weekly Digest Email Receive a weekly summary of recovered slots and revenue

Appointment Confirmations

Prevent no-shows before they happen

Confirm upcoming appointments Automatically text booked clients before their appointment — a reminder ~1–2 days out, plus a "reply C to confirm" the day of. If a client declines, SlotFill starts recovering that slot early. Catches ghosts before they cost you the slot.

Pause Mode

Temporarily stop all slot offer SMS

Pause SlotFill Cancellations will still be detected and queued — no SMS will be sent to clients until you un-pause. Useful for holidays, system maintenance, or when fully booked.

Quiet Hours TCPA

No SMS sent to clients during these hours

Enable quiet hours

TCPA guidelines recommend no marketing texts before 8 AM or after 9 PM in the recipient's timezone. Slots opened during quiet hours will be held and sent as soon as the window opens.

Recovery Rules

Control which cancellations trigger slot recovery

Minimum Appointment Value

$

Only attempt recovery for appointments worth at least this amount. Set to $0 to recover all cancellations.

Recovery Window

hours out

Only recover slots starting within this window. 72h = 3 days. Set to 0 for no limit.

Google Calendar Integration

Not Connected

When a cancelled slot is recovered and payment is confirmed, SlotFill automatically adds a calendar event so your schedule stays up to date.

Webhook Integration

Connect any booking platform via Zapier or direct API

Use this to connect platforms not natively supported (Booksy, Fresha, Square, GlossGenius, etc.) via Zapier or a direct HTTP POST. When an appointment is cancelled, your platform sends the event here and SlotFill handles the rest automatically.

Webhook URL

API Key

Keep this secret. Include it as api_key in your Zapier payload or as an Authorization: Bearer header.
