Every 10 minutes it looks for free capacity inside its horizon; when it finds some, it pushes the next clients into a Salesflow pipeline, where a WhatsApp or SMS agent offers them the slot. A client who books leaves the list; one who doesn't answer in time gives the seat back. **Calendar → Waiting Lists**. Waiting Lists index (1 lists · 4 waiting · 0 broken) with stat cards Clients waiting 4, Holding a seat now 0, Booked from lists · 30 d 0 and Needs a human 0, and one row 'Dermatology waiting list' tagged Dermatology with 4 waiting (0 queued · 0 snoozed · 0 flagged), status Active, next run 'Waiting for the first check' and a footer 'checks run every 10 min'. The index shows **Clients waiting**, **Holding a seat now**, **Booked from lists · 30 d** and **Needs a human**, plus each list's status: *Active*, *Paused*, *Broken* or *Needs setup*. ## Create a list **New Waiting List** offers three presets: | Preset | Horizon | Seat timeout | Attempts | | ------------------------------ | ------- | ------------------ | -------- | | **One list per department** | 14 days | 24 h | 3 | | **Single high-demand service** | 7 days | 6 h (cooldown 4 h) | 3 | | **Blank** | 14 days | 48 h | 5 | 'Waiting list · Configuration' side panel for the Active Dermatology waiting list showing Name, '1 · What it drains' with 1 service selected (Dermatology), Horizon 14 days, Max per run No cap, '2 · How it contacts' with Pipeline 'Dermatology waiting list · out…', Entry 'Waiting list', the agent line 'Appointments assistant · Vitalis Clinic', and Seat timeout / Contact cooldown / Max attempts fields above a Save button. | Setting | What it does | | -------------------------- | ---------------------------------------------------------------------------------- | | **Services** | Which services' capacity the list drains | | **Horizon** | How many days ahead it looks (1–30) | | **Max per run** | Cap on clients pushed per sweep | | **Destination** | The Salesflow pipeline and entry node that contact them — or **New from template** | | **Contact hours** and days | When clients may be contacted | | **Seat timeout** | How long a client holds an offered seat before it's released | | **Contact cooldown** | Minimum gap between two contacts to the same client | | **Max attempts** | Seats offered before the client is flagged *Needs a human* | **Readiness** checks run live: a blocking finding stops **Activate**; an advisory one lets you **Activate anyway**. ## The queue Dermatology waiting list detail page (Active, 1 services · 4 waiting · 14-day horizon) with capacity '70 openings for 4 waiting · Room for everyone', the Appointments assistant agent chip, Pause and Add Client buttons, and a Queue table of Noah Davis, Sophia Moore, Lucas Thomas and Charlotte Harris with Dermatology service, Waiting status, position, priority and preferences.
